Can Spreadstone be used on Integral Sinks?

We had a recent online question that we’d like to share here too.

Hi, we purchased the SpreadStone for our bathroom countertop and the sinks are integrated into the counter. Can the Spreadstone be applied to the sink? And if so, do we need to apply some sort of waterproofing? Thanks!

Answer:
Yes, you can apply it to the sink on an integrated countertop.

Use extra coating and sealer for the water prone areas. Optionally, you can apply our bonding primer (Elastolock) which comes in a quart. Use this primer before the first step, to bond to the tile and allow the coating to bond into the rubber well.

Integral sinks are made from the same material as the countertop they are set into. The effect is the seamless appearance of a smooth transition from sink to surface. … The lack of a seam between the sink and countertop does make cleaning significantly easier. You can retain the same effect by coating the whole sink with SpreadStone
