Everbuild 501 PVA BOND extended informationEVERBUILD® 501 Universal PVA Bond is a medium viscosity, polyvinyl alcohol stabilized, externally plasticised, vinyl acetate homopolymer. Contains no harmful phthalates. It has been designed specifically for use in the building industry as a general purpose bonding agent, and additive for concrete and plasters and as a multi-use adhesive.USESAs a general purpose adhesive for wood, cork, paper, textiles etc.As an admixture for mortar/screeds/renders.As a bonding agent for screeds/renders to difficult substrates.As a primer/sealer in tiling applications.As an internal filler when mixed with wood shavings plaster etc.EVERBUILD® 501 Universal PVA Bond can be used to stick paper, cardboard and other similar porous substrates.Everbuild 501 PVA BOND CHARACTERISTICS / ADVANTAGESGreatly improved adhesion to a wide range of substrates including dense concrete, glass, steel, tiles etc.Mixes may be applied in much thinner sections with improved resistance to salt permeation.Reduced surface dusting of concrete.Improves flexibility of sand cement products.Reduced water: cement ratio for equivalent workability.Improved frost resistance.Reduces surface porosity of mortar/plasterEverbuild 501 PVA BOND CHARACTERISTICS / ADVANTAGESTotal Solids32 - 37%Viscosity @ 23°C Brookfield RTV 5/207000 - 15000 cps @ 23°C -25°CMinimum Film Forming Temperature (°C)-2°C to 5°CHigh Temperature Stability (1 Week @ 50oC)StableEverbuild 501 PVA BOND PRODUCT INFORMATIONPackaging 1ltr, 2.5ltr, 5ltr and 25ltr - Jerry Can 500ml - Plastic Bottle. 1000ltr - IBCShelf Life12 Months from date of manufacture in original unopened containers.Storage ConditionsTo ensure safe storage of EVERBUILD® 501 Universal PVA Bond, containers should be well sealed to prevent evaporation of water and the formation of skin on the surface. The emulsion must be stored at a temperature above freezing. Storage temperature of 5°C - 25°C is recommended. Higher peratures will affect quality and cause the formation of crusts and skins, pecially if the containers are not tightly closed or subjected to direct light for long periods. EVERBUILD® 501 Universal PVA Bond exhibits excellent stability at high storage temperatures. After 1 weeks storage at 50°C no significant changes in viscosity were observed.Densityca. 1.07 g/cm3pH-Value4 - 6Everbuild 501 PVA BOND APPLICATION INSTRUCTIONSSurface PreparationAll surfaces must be clean, dry and free from grease.PRIMING AND SEALINGWhere the emulsion is to be used on porous substrates (old concrete, plaster, plasterboard etc.), it should be diluted 4 parts water : 1 part emulsion to seal the surface in preparation for further coating.BONDINGEVERBUILD® 501 Universal PVA Bond can be used to bond plaster and cement renders/repair compounds. To bond plaster, the emulsion should be used undiluted and brushed onto the surface to be plastered.Fresh plaster should be applied before the emulsion dries.The bond strength of the plaster to the substrate meets the requirements outlined in BS5270 (Plaster bonded to glass).To bond cementitious renders or repair compounds, two methods of use can be considered.i) Small areas:- mix EVERBUILD® 501 Universal PVA Bond with an equal amount of water and add this to the mortar/concrete mix (the emulsion exhibits excellent compatibility with cement). When added to a concrete/mortar mix, EVERBUILD® 501 Universal PVA Bond will improve adhesion and also flexural strength of the cured concrete in a similar way to conventional PVA bonding agents. ii) Larger areas:- dilute the emulsion, 3 parts emulsion : 1 part water and brush onto the surface to be coated/repaired. Apply a normal concrete mix before the emulsion dries.WOODWORKINGEVERBUILD® 501 Universal PVA Bond will bond wood in similar fashion to conventional bonding agents.The emulsion should be used neat in woodworking applications. In laboratory test, wood failure was observed in joints constructed with EVERBUILD® 501 Universal PVA Bond.In common with conventional PVA bonding agents, EVERBUILD® 501 PVA Bond should not be used for load bearing applications.LIMITATIONSNot suitable for external applications. Use EVER-BUILD 503 SBR BONDAs a wood adhesive, do not use as an externally / where water is likely. Use 502 All Purpose Weather-Proof Adhesive.
