Description

Everbuild 501 PVA Bond is a general purpose bonding agent, primer, sealer and admixture. It is a medium viscosity, polyvinyl alcohol stabilized, externally plasticised, vinyl acetate homopolymer that contains no harmful phthalates.

Everbuild 501 PVA Bond 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.

Everbuild 501 PVA Bond meets the bond strength requirements of BS5270, “Polyvinyl acetate (PVAC) emulsion bonding agents for internal use with gypsum building plasters”.

Benefits of using Everbuild 501 PVA Bond:

Greatly improved adhesion to a wide range of substrates including dense concrete, glass, steel, tiles etc.
Mixes may be applied in much thinner sections 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/plaster.

Universal polyvinyl acetate (PVA) adhesives or bonding agents find wide use in the building industry. The areas of use are generally non-specialised, however, there is a requirement to meet BS5270 “Polyvinyl acetate bonding agents for internal use with gypsum modified plasters”.

Everbuild 501 PVA Bond meets the requirements of the Universal PVA market and can be used in a similar fashion to other phthalate plasticised PVA emulsions and visually appears no different.

Everbuild 501 PVA Bond contains an environmentally acceptable non-phthalate ester plasticiser to enable low temperature film formation and confer film flexibility.

Bonding Agent Requirements:

(a) Fulfilment of the requirements detailed in BS5270
(b) Does not contain a phthalate ester plasticiser
(c) Good selling properties
(d) Effectiveness as a general purpose wood adhesive
(e) Compatibility with cement and gypsum
(f) Goods adhesion to concrete
(g) Excellent high and low temperature stability

Everbuild 501 PVA Bond meets all of the above requirements.

Everbuild 501 PVA Bond can be used:

As 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.

Limitations:
Everbuild 501 PVA Bond is not suitable for external applications. We recommend using Everbuild 503 SBR Bond.
This product is also not suitable for use as a wood adhesive, externally or for load bearing applications.

Surface Preparation:
All surfaces must be clean, dry and free from grease.

Storage:
To ensure safe storage of Everbuild 501 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. A temperature of 5-25°C is recommended Higher temperatures will affect quality and cause the formation of crusts and skins, especially if the containers are not tightly closed or subjected to direct sunlight for long periods. If these conditions cannot be met, please refer to our Technical Service Department who will advise on storage stability.
