Question: I have painted internal new plaster with SikaTop 121 polymer adhesive water component A On painting the plaster with an emulsion wash coat, the Sika treated areas will not take the paint. Which product can i use to cover the Sika to enable me to paint the walls? Regards Ruthie
Answer from Rawlins’ Technical Team:
Sikatop 121 was discontinued a few years ago, it was a waterproof levelling mortar so if the coating you are using is water based it will not take as the product is waterproof. If you use a solvent based paint instead of water based then it should bond to the substrate.
