Review: Great primer and excellent shipping - Normally I buy paints and primers locally and hadn't considered getting them online (from desertcart or anyone) as I didn't think the cans would survive shipping. I ordered this primer online because all of the local stores were sold out and I needed a quality stain blocking primer. First, let me share feedback on shipping and packaging. Inside the desertcart shipping box was a packing material and then a second box which contained the can. Around the can was cut out cardboard and held the can suspended inside the box. The can was in an airtight plastic bag that was sealed. The can itself came with a plastic lid sealer around the rim. All of that packaging must have worked because the can arrived in perfect condition with no dents or leaks. I am thinking about trying to order a gallon of primer and/or paint to see how it travels. For the primer itself, it is great stuff. Insul-X makes great primers that bond well, sand easily, and don't smell as bad as some other cheaper primers. I'll pay more for a primer that doesn't have terrible odors. I have used their Aqualock and Prime All primers which are both good for their intended purpose.
Review: Aqua Lock products have no comparison - Years ago I did my kitchen cabinets in Giani Coconut White. Sadly one drawer suffered every time I pull it out and reached for a utensil. My ring rubbed off the paint under the handle. Now, the cabinets had been pressboard brown 42 yrs ago. They had been pickled, painted, multiple times, and finally Gianied, with numerous coats of sealants . I realized that removing the handle and doing a deep sanding was labor intensive. I wondered if a touch up, using Aqua Lock White would do the trick after sanding. To my great surprise it went on very easily. It leveled out with the remaining paint. I am very pleased with all the Aqua Lock products I have used. They are far superior and preferred by refinishers. Now I know why.

## Questions & Answers

**Q: Which of these primers is best for kitchen cabinets?**
A: Aqua Lock will work over most kitchen cabinets. Adhesion works best with the proper cleaning and prep work before applying the primer to insure adhesion.

**Q: It says it's "sealer", but never said what it seals.  Does this guard the drywall against water damage, i.e. is it water proof?**
A: If you scroll down and read through the product description you will see that it includes drywall as a substrate it has excellent sealant properties for.  The description also says that it can be top coated with latex or oil-based coatings.  It's a primer not a finish.  How waterproof your project ends up being will depend on the combination of primer and finish.  This is a good product if properly applied and top coated, but no finish is waterproof in a flood.

**Q: Can it be used for pool?**
A: Hello, AquaLock is not designed for usage in environments that are under continuous moisture exposure. The INSL-X Pool Paints would be our recommendation. Please reach out to inslx . reviews @ gmail . com should you have any other questions.

**Q: what acrylic paint would you suggest to seal an asphalt shingle roof.  Is mineral spirits clean up a necessity?**
A: Hello, we do not recommend to use any of our coatings on an asphalt shingle roof.

### ⭐⭐⭐⭐⭐ Great surface primer
*by E***L on June 13, 2025*

Used it as a primer on a newly drywalled ceiling and it covered well and sealed the surface really good. We applied paint over this primer and it spread really nice and we saved quite a bit of paint using this primer first. I does need time to cure before applying paint and it is very low odor almost unnoticeable. Great product as a primer for drywall and msg also.
