## Questions & Answers

**Q: this water-based?**
A: Yes. Cleans up with soap and water. Seems waxy.

**Q: Hello, Do you have to re-apply every year?**
A: Probably. To tell, splash some water on the finish. If the water forms bubbles, the surface is OK for another season. However, after a year the surface may look dirty, and so you may want to clean it and re-seal it. Again, after you clean the surface, splash some water on it and see whether the previous seal still holds.

**Q: How  many  years should I reapply this product over again?thank you for your response ?**
A: We use it every 3-5 years on our fence

**Q: Will this work over stained wood**
A: I used it on the stained wood deck of my flatbed truck. Works fine,

## Customer Reviews

### ⭐⭐⭐⭐⭐ Indoor use approved
*by K***T on August 31, 2022*

After destroying many desk surfaces over the years with minor coffee, water and tea sloshes (or just moisture rings) I decided to invest a little extra in my corner desk purchase by getting this waterproofing wood seal. As per the directions, I applied it to the cleaned and dried surface of the desk, fairly easy to get a nice even layer, and let it sit to cure before lightly buffing the surface. I worried it might be too waxy/thin; it looked like I’d removed it once it was dry but I tested a bit if water spillage and it beaded, not penetrating the surface at all. I’ve run my nails and the usual mugs over the surface and it has made good on protecting the surface. It doesn’t feel weird to touch or stick to clothes or fabrics either. I imagine it probably has more longevity for indoor use, not being exposed to elements or used as an indoor coffee slip and slide game so I probably won’t need more than the single application for the life of the desk. However, I keep it handy for any and every furniture sealing project around the house because I’m very happy with the result. It works on laminate/cheaper furniture as well, not just wood. I’ll suggest always doing a patch test before risking anything you’re not personally familiar with. Some people’s DIY dreams are another’s DIY nightmare.
