Product Details


  • 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.

Haven’t used it yet, but I’m sure it’s great!

Cover All

My first time using it and I love it. Completed two tumblers so far and I had no problems with either of them. It goes a long way as well.

Cover all

Love it!!! Works great! I even put it over a tumbler I have made before and didn’t strip anything off of it. I just then redid the tumbler with uw, glitter,,Waterslides and liquid mica with BT then GF.

Not sure what to think...

I wanted to love this product but when i use blue tape to make lines it peels up with it. I could be doing something wrong... how can I get some help?
