Details

A premium grade SBR designed to give concrete floors and cement renders abrasion, chemical and water resistance. Bond It SBR also shows improved performance as a key coat adhesive compared to non SBR bonding agents.

 

Uses

For improving a mortar's, render's or floor screed's abrasion and chemical resistance. Providing protection during continued or intermittent water contact suitable for either external or internal use application. Key coat applications to substrates with a low porosity. For repair patching of concrete and cement screeds, to improve adhesion and flexibility of screeds.

 

Application

All surfaces should be free from laitance, oil, grease and standing water. Unsound surfaces should be

scabbled down to a solid base material.

 

Key Coat: Mix 1 part Bond It SBR to 2 parts cement by volume and adjust to brushable consistency with water. Mix only enough to use within the hour.

Brush thoroughly into a clean dust free substrate, whilst still wet overcoat with the floor or render mix.

 

Damp-proofing: Mix the same formulation as in the key coat and apply the first coat with vigorous brush strokes. Allow to touch dry then apply a second coat at 90° to the first and allow 48 hours to dry. Apply the third coat at 90° to the second coat and while still wet apply the render.

 

Renderings/Mortars: Prepare the substrate with the key coat first for best results. Mix sand/cement mortar/render and add 5-7.5 litres Bond It SBR per 25Kgs cement, reducing the amount of gauging water accordingly. Apply at least 6mm thick. Two coats are recommended.

 

Granolithic Floorings: Prepare the substance with the key coat first for best results.
