Joint surfaces shall be dry, clean and free from contamination. Any voids or gaps at the base of the sealing slot should be filled, and a suitable bond breaker should be pushed into construction and contraction joint slots. Where a particularly neat finish is required mask edges of joint before priming (if needed) and application.
Where surface shall be subject to submersion or permanently damp, joints should be primed using Fosroc Primer MS2. Decant the entire contents of primer curing agent into the primer base tin and replace the lid. Mix thoroughly by shaking tin for about 2 minutes. Apply the primer using a clean, dry paintbrush. Nitoseal PU800 should be applied between 30 minutes and 4 hours after priming.
