UNIVERSAL

ADHESIVE, SEALER & CONCRETE ADDITIVE

Polybond   is   a   universal   product   for   use   with   practically   every   type   of building   material.   It   is   a   safe,   effective   and   easy   to   use   adhesive,   an efficient   sealer   and   a   cement   additive   producing   concretes   of   quite exceptional   quality   and   adhesion.   It   is   non-toxic,   non-inflammable and almost odourless. Main Uses And Advantages Of Polybond • Polybond   will provide an immediate key on any existing sound surface to enable   cement   or   plaster   renders   to   be   applied,   with   the   knowledge   that these renders will hold positively even under the most severe conditions. • Polybond    does   away   with   the   time   and   labour   costs   involved   in   hacking surfaces to provide a key. • Added   to   a   standard   cement   mix,   Polybond    will   ensure   tough   dust   free concrete,   having   a   greatly   enhanced   strength   and   wearing   quality   plus   a better resistance to mild acids, alkalis, lactic acid, animal urine, oils etc. • Polybond    makes   repairs   to   concrete,   stone   and   granite   supremely   easy and sure. • Diluted,    Polybond    will    prime,    seal    and    stabilise    all    porous    surfaces ready for painting. • High   quality,   low   price   fillers,   tile   adhesives   and   emulsion   paints   can   be made up using Polybond . • Full   Strength   Polybond ,   as   supplied,   is   very   cost   effective.   For   nearly   all applications, the product is diluted with water before use. Application Polybond    may    be    applied    by    brush,    roller,    spray    gun,    squeegee,    soft broom   etc.   All   equipment   should   be   washed   thoroughly   with   clean   water immediately   afterwards.   When   using   Polybond   as   an   adhesive,   the   bond should always be made whilst still wet and tacky. Preparation It   is   important   that   surfaces   are   clean,   sound,   and   grease   free.   Loose materials,   powders,   oils   and   greases   should   be   completely   removed   using Polybond   Concrete   Cleaner    whilst   Polybond   Fungicidal   Wash    is   the ideal   product   for   killing   fungi   and   stopping   mould   growth.   All   porous surfaces   should   be   primed   with   a   solution   of   one   part   Polybond   to   five parts   water   by   volume   brushed   well   into   the   surface   and   allowed   to   dry. Iron   and   steel   must   be   treated   with   a   rust   inhibiting   primer   paint   or treated with Polybond Rust Converter . Dilution and Coverage These   will   vary   depending   on   the   porosity   and   smoothness   of   the   surface to   which   Polybond   and   its   various   dilutions   are   applied.   However   the following figures based on site reports will act as a general guide:

Polybond + Water Full Strength 1 part + 1 part 1 part + 2 parts 1 part + 3 parts 1 part + 5 parts 1 part + 10 parts

Polybond As a General Adhesive Every   type   of   building   material,   except   polythene   and   thin   rubber   can   be successfully   stuck   with   Polybond .   Many   workers   simply   apply   undiluted Polybond   to   both   surfaces,   wait   till   tacky,   then   bring   together   under   hand pressure   only.   It   is   generally   recommended   however,   that   surfaces   should be   given   a   priming   coat   diluted   with   water,   prior   to   applying   the   product neat.    Porous    surfaces    should    be    primed    with    Polybond     diluted    with about   five   parts   water.   On   very   porous   surfaces   liable   to   suction   such   as asbestos board, Dilute with five to ten parts water. Non-porous   surfaces   such   as   formica,   glass,   metal   etc.   should   be   primed   with Polybond   and   water   at   1+2.   Bare   steel   should   first   be   primed   with   a   suitable metal primer. The product can be applied direct to galvanised steel. For joinery work dilute 1+1 with water and prime as above. Do not over-clamp as with old fashioned   glues.   Tight   clamping   may   drive   the   adhesive   out,   particularly   at   the edges and weaken the bond. See Wood and Joinery Applications. Concrete, Cement and Plaster 1) Bonding New Concrete to Old. Polybond    provides   an   immediate   key   between   new   and   old   concrete. Note that no hacking or joint racking is required. Method:   Thoroughly   clean   the   surface   of   oil,   grease   and   excess   laitence   etc. Thin   some   Polybond   with   five   parts   or   water,   apply   and   allow   to   dry.   Bruch on   another   coat   of   Polybond   thinned   with   three   parts   of   water.   Allow   this second coat to become tacky, then float on the new concrete mix. 2)   Bonding   Concrete   or   Plaster   to   Asbestos,   Brickwork,   Blockwork, Metals, Wood, Terrazzo etc. Method: As in 1) above. 3) Repairing Concrete Floors and Stairs. Repairs   can   be   made   from   a   feather   edge   to   an   inch   or   more   thick.   They will be tremendously strong and stand the hardest wear. Method:    Thoroughly   clean   surfaces   to   remove   oil,   grease   and   dirt.   Seal the   surfaces   witha   mixture   of   Polybond   and   Water   1   +   5.   Allow   to   dry. Take   required   amount   of   dry   sand   and   cement   and   use   Polybond   and water   at   a   1   +   3   to   make   this   into   a   workable   mass.   Apply   the   cememnt mix, and lay-off with a steel trowel. 4) Filler for Gaps, Cracks, Holes etc. Polybond   makes   an   ideal   filler   for   joints,   gaps,   cracks,   holes   etc.   on   all types   of   building   surfaces.   It's   use   substantially   reduces   the   shrinkage experienced with some fillers. Method:    Make   up   an   adhesive   mix   of   either   cement,   plaster,   wood   flour or branded filler using Polybond and water diluted 1 + 3. 5) Mortar Joints and Pointing. To   Improve   mortar   joints   and   pointing   in   new   and   old   brickwork,   use method 1) above. 6) Plastering and Rendering without Keying. Polybond   bonds   all   plasters   to   surfaces   rough   and   smooth.   These   include shuttered concrete, glazed bricks, tiles and painted brickwork.

Method:    All   types   of   plaster   or   render   may   be   bonded   to   normal   porous surfaces by using the method in 1) above. When   plastering   or   rendering   over   non-porous   (eg.   glazed   or   painted surfaces)   or   for   renders   greater   than   12   mm   thick,   work   as   follows.   Make sure   the   surfaces   are   clean,   dry   and   grease   free.   In   the   case   of   tiles   or ridged   laminates   etc.   clean   carefully.   Mix   two   parts   of   washed   sharp   sand and   one   part   cementm   wet   down   with   Polybond   and   water   1+2.   Apply   as a   slurry   with   a   fairly   stiff   brush   or   6mm   notched   trowel.   Rub   up   and   score. Allow   to   dry   thoroughly   for   at   least   twenty   four   hours.   Apply   new   plaster or   render.   Note:   Polybond   complies   with   BS   5270:1976   Polyvinyl   Acetate (PVAc) Bonding Agents for internal use with gypsum building plaster. Admixtures with Polybond When    added    to    ordinary    plaster    or    sand-cement    renders,    Polybond ensures    that    the    finished    plaster/render    will    have    a    fineness    and toughness   which   improves   its   resistance   to   penetration   by   damp   and other   liquids.   It   will   also   enable   subsequent   decorative   treatment   to   be carried out without the necessity for any special priming costs. Method:   Simply   substitute   the   normal   gauging   water   by   Polybond   and   water 1 + 5. Added to standard concrete mixes, it gives vastly improved properties to the   concrete.   The   concrete   is   dust   free,   has   greater   resilience   and   tensile strength.   There   is   no   change   in   the   rate   of   curing.   Polybond   should   be   added at   the   rate   of   from   1.5   litres   to   10   litres   per   standard   (50kg)   bag   of   cement depending   on   the   quality   required,   together   with   water   and   aggregate   in accordance   with   normal   building   practice.   Alternatively,   substitute   the   usual plain gauging water for a mixture on one part Polybond and from three to five parts   of   water.   Note:   Add   the   Polybond   first   to   the   dry   mix   and   then   add   the required gauging water. This avoids making the mix too wet. Concrete Floors Bonding a New Concrete Floor and Screed to and Old Sub-Floor When    laying    new    concrete    on    old,    all    hacking    to    obtain    a    key    is unnecessary.   Application   method   is   per   1)   above.   Lay   section   by   section whilst   the   bonding   coat   is   still   tacky.   If   the   bonding   coat   is   allowed   to   dry out   first,   then   the   plain   gauging   water   of   the   mix   must   be   substituted   by Polybond diluted 1+3 with water. Plain   cement   floors   generally   have   a   number   of   disadvantages.   Polybond overcomes   these.   Incorporated   in   a   standard   mix,   it   produces   a   floor having   increased   resilience   and   resistance   to   attack   by   many   common substances   to   which   concrete   is   prone   ie.   beer,   yeast,   milk,   acids,   urine, water   etc.   The   presence   of   Polybond   ensures   that   the   new   floor   will adhere soundly to the old floor. The floor will also be dust free. Almost   any   type   of   sub-floor   is   suitable   for   supporting   a   new   Polybond floor.   It   must   however,   be   sound   and   clean   and   have   an   effective   DPM.   It is   essential   that   no   oil   or   grease   be   present   and   laitance   be   removed   as far   as   possible.   A   commercial   cleaner   such   as   Polybond   Concrete   Cleaner will assist in thorough preparation. Feather Edging One of the important advantages of a Polybond floor is that the thickness can be   taken   down   to   a   feather   edge.   This   is   particularly   useful   when   bonding   a new   floor   to   an   existing   worn   surface   and   when   the   problem   of   differing floor   heights   may   arise.   Therefore,   under   doors   etc   a   Polybond   floor   can   be made as thin as necessary without risk of weakness or loss of adhesion.

Stronger Floors New   floors   can   be   laid   having   a   range   of   qualities   depending   upon   the amount   of   Polybond   used   in   the   mix.   Substituting   the   usual   plain   gauging water    in    a    mix    by    Polybond    and    water    1    +    3    will    produce    a    floor    of exceptional   strength   and   flexibility.   This   is   the   equivalent   of   about   6   litres of   Polybond   per   50kg   of   cement   and   assumes   that   up   to   25   litres   of   water are      usually      used      with      each      50kg      of      cement      in      an      average cement:sand:aggregate   mix   of   1:2:4.   As   little   as   1   litre   of   Polybond   to   each 50kg   of   cement   will   product   markedly   improved   concrete.   Note   that   not more than 10 litres of Polybond to each 50kg of cement should be used. Plastic Floor Screeds A   plastic   screed   has   only   one   third   the   thickness   of   a   conventional   screed and   this   brings   real   savings   in   time,   labour,   weight   and   cost,   with   positive adhesion   to   the   sub-surface.   Therefore,   the   laying   of   a   Polybond   Plastic Screed    instead    of    a    conventional    one    is    an    obvious    advantage    to    the builder.   A   37   mm   conventional   screed   would   be   replaced   by   a   12   mm Polybond Plastic Screed. Method:   A   1+5   Polybond   to   water   dilution   is   simply   brushed   on   to   the clean   sub-surface   and   allowed   to   dry.   This   will   obviate   all   hacking.   The following screed is then mixed. Sharp sand (washed)   3 parts by volume. Cement 1 part by volume. Wash   down   to   trowelling   consistency   with   a   1+10   Polybond   and   water mix   and   apply   the   screed   in   conveniently   sized   bays.   Drying   out   should   be controlled and the floor covered for 18 to 24 hours with polythene. Dust-proofing Floors To   dust   proof   all   types   of   cement/concrete   flooring,   apply   one   or   two coats of Polybond and water 1+5. Priming, Sealing and Painting Porous Surfaces 1) Polybond Stabilising Solution Polybond   and   water   1+3   is   the   perfect   sealing   and   stabilising   medium   for porous   surfaces   such   as   bricks,   cement   and   concrete,   plaster,   asbestos, hardboard,   chipboard   etc.   Any   type   of   paint   or   emulsion   paint   may   then be   applied   over   Polybond .   Crumbling,   porous   surfaces   can   be   improved by   using   the   following   method.   Brush   off   loose   dirt   etc,   apply   a   coat   of Polybond   and   water   1+5   and   allow   to   dry.   Then   apply   a   second   coat   of Polybond and water 1+3. Allow to dry. 2) Emulsion Paint Equal   parts   of   Polybond   and   water   added   to   emulsion   paint   will   make   an undercoat   that   will   ensure   thorough   binding   of   under   surfaces   and   save   a second finishing coat of emulsion. 3) Distemper Polybond   will   change   ordinary   distempers   into   inexpensive,   high   class emulsion    paint.    Simply    add    500ml    of    Polybond    to    every    5    litres    of distemper. Tiles Fixing Tiles Polybond   offers   by   far   the   easiest   and   cleanest   method   for   attaching   tiles to   any   sort   of   surface.   They   can   be   laid   on   floors   or   walls,   on   flat   or uneven   surfaces.   The   following   method   can   be   used   for   many   types   of   tile including    acid    and    alkali    resisting,    acoustic,    cement,    cement/asbestos, cork, glazed and quarry tiles. Method:    Brush    over    the    entire    wall    or    floor    area    with    a    mixture    of Polybond   and   water   1+5.   Allow   to   dry.   This   can   be   done   at   any   time   and left   until   ready.   Use   the   same   mix   to   prime   the   back   and   edges   of   the   tile. Any   number   can   be   prepared   and   held   in   stock   indefinitely.   Make   up   a   mix of   Polybond   and   water   1+3   and   stir   in   cement   for   form   a   smooth   workable mass.   Apply   this   adhesive   mix   at   no   more   than   6mm   thick   to   the   backs   of the tiles. These can then be stuck straight on to the primed surface. There is a firm instantaneous bond but the tile can be slid into any position. This   method   can   also   be   used   for   replacing   loose   or   broken   tiles   etc.   If surfaces are smooth, undiluted Polybond may be used as an adhesive. Wood and Joinery Applications Polybond   is   outstanding   for   bonding   wood,   hardboard,   chipboard   and composites    to    each    other    or    to    other    materials    including    glass    and metals.   No   heating   or   mixing   is   required   and   the   dry   bond   never   goes brittle.    Tack    is    developed    very    rapidly,    yet    it    is    possible    to    adjust    the assembly   after   the   joint   is   made   without   difficulty.   No   excessive   cramping is   required   and   in   many   cases,   hand   pressure   is   sufficient   to   give   a   bond of   enormous   strength.   When   quite   dry,   the   joint   is   stronger   that   the   wood itself!   It   can   be   used   on   flat   surfaces,   edges   and   end   grain.   Bond   strength on tenons, halving and flats exceeds 125.8kg/cm².

Method:    Clean   the   surface   to   be   coated.   Apply   Polybond   and   water   1+1   to both    surfaces,    allow    to    become    tacky,    then    bring    the    coated    surfaces together under moderate pressure. If surfaces are non-porous, use undiluted. Plastic Wood A   first   class   plastic   wood   can   be   made   by   adding   wood-flour   or   sawdust   to Polybond and water 1+1. Method:   Make   up   a   paste   with   sawdust   or   wood-flour   to   the   required consistency.   Add   stainers   to   tint   if   desired.   Apply   in   the   usual   way   and allow to dry off completely before working the surface. Paper Sealer and Adhesive Polybond   is   a   first   class   clear   glue   for   sticking   paper,   prints,   drawings, maps etc. to boards and walls. Method:   Apply   Polybond   diluted   with   an   equal   volume   of   water   to   the surfaces   it   is   desirable   to   stick.   Allow   them   to   become   tacky   and   bring together.   Expel   any   air   bubbles   outwards   by   means   of   a   squeegee   or roller,    or    by    smoothing    with    the    hand.    As    an    alternative,    wait    for    the adhesive   to   dry   thoroughly   then   iron   on   to   the   substrate   using   a   medium heat and protective over-sheet. Sealer A   simple   coat   of   Polybond   and   water   1+3   applied   to   the   surface   gives permanent   protection   from   dirt   and   grease.   Polybond   diluted   with   water 1+3   used   as   a   sealer   will   protect   wallpaper   from   dirt   and   grease   which   can then be easily wiped off with a damp cloth. Lapping Winyl Wallpaper Simply   coat   undiluted   Polybond   onto   both   surfaces   and   bring   together wiping   away   any   excess   before   it   dries.   The   product   is   recommended   by leading wallpaper manufacturers for the lapping of vinyl papers. Sealing and Binding Carpets Polybond will bond carpets, sacks, mats, all trimmings and fittings. Method:    Apply   a   coat   of   Polybond   and   water   1+1   to   both   surfaces   to   be bonded.    Allow    to    become    tacky    and    then    bring    them    together    under moderate pressure. Wilton Carpets Cut   the   carpet   from   the   back   to   the   size   required.   Apply   undiluted   to   the edge and back for about 25 mm from the edge. Allow the Polybond to dry and the binding is complete. Axminster Carpets Fray   out   the   carpet   ends   by   pulling   out   the   cross   weft   for   about   25mm, apply   Polybond   in   a   25   mm   strip   to   the   back   of   the   carpet   and   fold   the ends   down   on   to   this   strip.   To   complete,   paint   over   the   ends   and   allow   to dry. Bind the edges as with Wilton. Coco Matting Liberally   apply   Polybond   to   the   edge   taking   it   back   about   50mm   to   bind, allow to dry before use. Rope Ends These will never unravel if they are dipped in Polybond. Method: Twist together and dip into Polybond . Allow to dry. Important Note One    of    the    uses    of    Polybond    is    to    provide    a    bond.    If    surfaces    are    badly prepared,    or    inferior    materials    are    present,    it    cannot    do    this.    Certain substances,   particularly   distempers,   lime   washes   and   emulsion   paints   may   in time   be   unable   to   bear   the   weight   of   renders,   coats   of   cement   etc.   Unless   firm and permanent surfaces are present Polybond should not be used.
