Can Sikalastic 1k be painted over with a good quality masonry paint . Would it require a primer or is it just not suitable .
This can be over painted, if a solvent based paint is to be applied on Sikalastic®-1K, carry out preliminary testing in order to ensure the solvents do not attack and damage the waterproofing layer.

Can you plaster on top of this product?
You can, although we wouldn't advise it. Sikalastic 1k is polymer modified and flexible, plaster is fairly rigid, this may cause cracking in the plaster if movement occurs.
