## Questions & Answers

**Q: can you mix this with the resin and use a spray gun?**
A: When I received the undercoat 90% of the can was hard. The product was no good. I tried to contact the seller and they never responded so I returned it. So what I started to use was Kitz primer from Home Depot. It works fine so far and I have done 2 projects so far. I do property flips and I am working on a 4000 sq. ft. house with all the counter tops done with Resin. I have studied the Stone Coat Countertops video as they are very good to watch and learn. Its to bad there customer service really sucks.

**Q: Is it normal for it to be solid when you get it?**
A: Mine was solid too, ordered Feb 12th. I'm confident it's not supposed to be that way.

**Q: Si utilizo esta base y quiero dejarlo blanco puedo colocar directo el clear sobre ella sin que se ponga amarilla?**
A: A mi se me puso amarillo no se si fue la base o el clear

**Q: How do i prep ceramic tiles before base coat application?**
A: Step 1: Clean the surface with trisodium phosphate (TSP), which is purchased at any paint store made for paint prep and deep cleaning.

Step 2. Sand with a rough 60-grit sanding disc attached to a random, orbital sander.

Step 3: Apply a thin coat of bonding primer and let it dry completely.

Step 4: Apply the thin-set and liquid polymer mixture to float the tile and fill in grout joints. Here are links to the VersaBond Thin-set and the Quikrete Liquid Polymer.

Step 5: After you’re done with the thin-set and it’s dry, you can use a concrete rubbing stone to remove ridges. Here is a link for it: 20 Grit Concrete Rub Brick.

Step 6: Now you apply a self-leveling underlayment and liquid polymer mixture. Here is a link to the LevelQuik.
