  • Eliminate Prep Sanding - yes, you read that right. Cover All is a prep coat that removes the need to sand or strip your tumblers before decorating!
  • Breathe Easy - Our waterborne formula is non-toxic, eco friendly and does not require special PPE.
  • You're a Pro - The work is done in the bottle so that you can focus on doing your thing. Just brush it on! Cover All will self-level as it dries.
  • Skip to the Fun - Now that you don't need to sand or strip, you can get to the fun stuff quicker and increase efficiency.
  • Clean with Water - Cleanup is quick and easy without requiring harsh chemicals.


  1. Environment: A temperature between 68ºF and 75ºF is ideal.
  2. Application: A dry, soft bristled brush works best. Use plenty of Cover All to get good coverage. If you see any repelling while it's wet, brush over it a few times until it fills in.
  3. Dry Time: Use 2 coats to ensure complete coverage. Ensure 2 hours of dry time between coats. A warm lamp hanging above it helps it to cure faster. You can also heat set Cover All by using a heat gun set on LOW, moving quickly and not too close. Be careful though, if you get it too hot, it can blister.
  4. Tinting: You can tint the Cover All by adding a few drops of our concentrated pigments and micas into it. Do this on the second coat. The first coat needs to be undiluted and pure for best adhesion.
  5. Curing: Cover All takes approximately 8 days before it becomes permanently adhered. No worries, you can still continue with your design 2 hours after the last coat. Cover All will continue to cure along with your other products as they dry. DO NOT pick or scratch off the Cover All while it is curing!

Remember, Cover All is a prep coat ONLY and does not work as a top coat.

Absolutely love this product! I used Cover All to cover a powder coated tumbler. I was surprised at how easy it was to apply with the fan brush. After two coats my tumbler was so smooth and ready for the next steps. This product is a game changer for sure!!! Don’t sleep on this amazing product!

Magic in a Bottle

I love that there is now a nontoxic and easy alternative to prepping surfaces! So easy to apply and much better than trying to sand ceramic tiles for coasters. It's seriously pure magic!!

I received my Cover All this afternoon and I was able to put it on my cup with no hassles of dragging everything out and not knowing if I prepped my tumbler the correct way. I also love the way the paint went on so smoothly.

I was so excited to hear this was coming out! I couldn't wait to get my hands on Cover All so I could start working on powder coated tumblers and also to give my hands a break with sanding. Boy was it worth the wait!! I'm loving it so far and can't wait to do more.

OMG! I love this stuff. So easy to use, no stripping the powder coating off, no sanding, and like all other Crystalac products it’s safe.
