Premium Co-Polymer Bonding Compound for adhesion and improving flexibility, durability and waterproofing.

Premium Co-Polymer Bonding Compound for adhesion and improving flexibility, durability and waterproofing.

KA-Bond SBR is designed to be added to mortar, screeds or renders to provide flexibility and durability along with a waterproof finish.

KA-Bond SBR can also be used prior to the application of renders, screeds or slurries to provide a strong adhesive bond that will not re-emulsify.

Before using a KA-Bond SBR based primer it is important to ensure that the surface to which it is to be applied is clean and free from dust and loose material, and has sufficient mechanical strength.
Preparation eg. wire brushing: It is recommended that concrete or masonry surfaces are well dampened an hour or so before priming (unless already damp, eg. basement walls) and should be damp but surface dry when the primer coat is applied.
When used as a bonding agent below mortars, renders, screeds and toppings the priming mix must be vigorously brushed into the prepared background and the mortar, etc. applied while the priming coat is still wet or tacky, usually this should be within 20 minutes depending on conditions.
Cleaning of equipment All tools should be cleaned immediately after use with water because hardened primers have excellent adhesion and are therefore difficult to remove. Solvents such as white spirit, used with coarse wire wool, help to remove partially hardened mixes.

This will depend upon the SBR/cement ratio and the background. Typical coverage rate on rough concrete is 0.3 to 0.4 litres of SBR per m² per coat. When used as a coating, as opposed to a bonding agent, the thickness of each coat should not exceed 0.5mm to minimise the risk of cracking.
