Question: 

Can you plaster on top of this product?

Answer: 

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.
We would instead suggest using Sika Damp-proofing Slurry as a rigid alternative and then plastering over this. Please note, any plaster needs to be non gypsum based.
