Notes:

Sika Damp-proofing Slurry does not provide a trafficable finish on floors it will need to be protected with a levelling screed.

Special attention is required to avoid puncturing the waterproof coating with fixings, these should be accommodated either by surface bonding

with Sikaflex EBT adhesive or similar high bond adhesive.

Sika Damp Proofing Slurry will not bond to surfaces that have been treated previously with a water repellent, finishing plasters may take longer to set when applied over the Damp-proofing Slurry.
