Description

Bond It PVA Adhesive & Sealer is a plasticised, premium PVA resin emulsion with good adhesion to porous materials. Phthalate free formulation. Conforms to BS5270.

PVA BOND ADHESIVE & SEALER can be used with plaster, cement, timber, gypsum wall boards and paper. Properties as an adhesive include fast drying. It is also a readily dilutable primer for sealing applications or addition to cement and plaster to improve adhesion and cure. Applications Plaster primer, porous surface primer and sealer. Rendering key coat. Admixture. Dust sealer. General purpose adhesive for bonding all common construction materials provided one surface is porous.

Preparation: All surfaces must be clean, dry, sound and free from dust, grease or contaminants that may hinder adhesion. Remove all loose material and ensure underlying material is strong enough to take the weight or load to be applied. If required, a sealing/priming coat should be applied and allowed to dry thoroughly prior to the application of Bond It PVA BOND ADHESIVE & SEALER.

Features and benefits

Application As a primer: Suitable as a primer for sand/cement screeds and renderings, for bonding new plaster onto old plaster, on porous brick, stone, floor tiles and new plaster board. Dilute 1 part PVA with 4 parts water and mix well. Apply using a brush, working material well into crevices and gaps. Allow the coat to dry before continuing. For cement: Dilute 1 part PVA to 1 part gauging water. For Plaster: Dilute 1 part PVA to 5 parts gauging water.

For dustproofing: As for priming. Key coat & bonding aid: For use as a key coat for new plaster, concrete repairs, cement screeds and renders. After priming absorbent surfaces as described above, apply a coat of undiluted PVA BOND and apply topping whilst the coating is almost dry but still tacky. As a key coat for ceramic tiles (note: not suitable for use in bathrooms) and painted surfaces, first ensure that the surfaces will withstand loading of new plaster. Apply BOND IT PVA BOND undiluted and trowel on plaster whilst still tacky. As a key coat for lightweight plasters over painted ceramic tile surfaces and heavy duty cement rendering (over 9mm). Mix 1 part PVA with 1 part water and use to slurry a blend of 1 part Portland cement to 2 parts clean sharp sand and apply with a notched trowel. Allow to dry for a minimum of 24 hours and then apply a top coat of plaster or cement. Key Coat for porous and rough surfaces, bonding paving, terrazzo, quarry, slate and floor tiles. Prime the floor and back of the tiles as specified under priming. Mix 3 parts PVA with 1 part water and coat floor and tile backs. While still tacky apply sand and cement slurry to the floor and bed in the tiles.
