Contractors PVA London Builders Merchants

Contractors PVA is a multi-purpose primer, sealer, cement and plaster admixture that adheres to most common building and DIY materials. Ideal for priming and dust sealing on flaking surfaces and as an adhesive on wood, cork etc.

Available in 5ltr & 25ltr

Mortar Ad Mix Surrey Builders Merchant

Mortar Admix is an air entraining plasticiser that replaces lime in the mix to provide an easy to work “butter like” consistency to the mortar and to prevent shrinkage, cracking and crazing during the setting process. For use in brick laying and plastering mortars. Provides a degree of frost resistance and long term resistance to freeze-thaw cycles when set.

Available in 5ltr & 25ltr

Sika®-1 Waterproofer is an aqueous solution containing complex colloidal silicates. In the presence of water these swell and block the capillaries and pores in the applied sand/cement renders, screeds and mortar to provide an effective barrier against the transmission of liquid water.

Brick & Patio Cleaner is a fast acting acid based formula (9.5% strength) that dissolves mortar and cement stains and ingrained dirt and paint on most mineral surfaces such as brick, stone, concrete, paving flags and earthenware. Please note this product is only suitable for external uses.

Concrete Hardener & Dustproofer is formulated from high quality silicate resins to both harden and dustproof new and old concrete floors for both internal and external use. It reacts chemically with the lime content of concrete to form a hard-wearing surface.

Integral Liquid Waterproofer is a liquid additive that provides long term water protection to mortar, concrete and rendering. Reduces water permeability and is suitable for all applications where resistance to water absorption is necessary such as pool and tank linings, roof areas, external rendering and pointing and structures below ground level.

Accelerator & Frostproofer is a liquid additive formulated to accelerate setting and hardening times of mortar, concretes, screeds and rendering to provide frost protection during the setting period. Effective even in sub-zero temperatures and can also be used in normal temperatures where a rapid set is required and as a plugging admixture.

SBR Bond is a latex based, water resistant bonding agent and admixture for use in areas subject to humidity, dampness and continuous water contact. Improves water resistance of cement mixtures by forming a reinforcing polymer that increases long term durability and flexibility of the mix on renderings and floor screeds.

Path & Patio Seal is a solvent free acrylic coating used to seal and protect patios, paths, natural stone, concrete and block paving from the effects of sunlight, water, oil, petrol and fungal/moss growth. The milky solution dries to a clear hard-wearing, water repellent film giving a low sheen slip resistant finish.

Evermix 3 in 1 triple action admixture waterproofs, plasticises and retards to assist workability, reduce water penetration and allow larger areas to be covered in one application. Evermix 3 in 1 is particularly formulated for use in renders, dry dash and pebble-dashing, however it can also be used in any cement mixture where waterproofing and increased workability are required in conjunction with retarded setting.

DPM. is an odourless rubber enriched bitumen emulsion which provides a highly effective sandwich damp proof membrane for floors. Also acts as a waterproofer for walls, above ground structures and foundations. DPM is also suitable as an adhesive for wood block and mosaic panels, insulation boards, expanded polystyrene, cork and as a plaster bonding agent, even on difficult surfaces.
