📝 My Hands-on Test of Dap Silicone

DAP 08641 100% Silicone Sealants
I found Dap Silicone to be very good for leaks in vehicles, as it holds to the metal well and the white color blended with the top of my van.

I had a cracked RV fan cover that got damaged during a tornado warning in Kansas, and it got hit with hail repeatedly for almost an hour. Weather tape and this caulk fixed it and it has held up for several months now with no leaking.

I also had a water leak just above the seam where the left side of the side sliding door connects. It leaked water into the van every time it rained. I got on top of the van, applied this to the cracked seam, and it’s held up for several months now with no leaking. I’m pretty sure this could be used on other vehicles as well that are in different colors.

When I needed a great watertight seal for a fountain that I made and needed to seal a glass lampshade to a glass block, Dap Silicone worked great! Even when temps have gone below freezing it still holds water. However, it does have an intense vinegar smell that burns your nose hairs and remains on it after it’s cured, so I recommend wiping the finished products with a bit of alcohol and spraying with no-oil alcohol-based fragrance spray to cover the stink.

seal the water leakage of the toilet tank with Dap Silicone
It does a perfect job of sealing water leaks in a toilet tank. The screws that hold my toilet tank in place had rusted away and fallen out completely. To use this sealant, I put on a vinyl glove and applied it in layers over the top of the screw holes. I needed to apply several layers since the sealant was not easy to apply in one coat.

In my opinion, Dap Silicone is 10x as hard to work with as water-based caulks. Just saying, if you need structural quality and are not so worried about a finished edge, this is probably your stuff. If you are a clumsy caulker, or want a forgiving product, then this is probably not for you. It adheres really durably even to smooth surfaces, and I used this for decoden phone cases as “icing” and even though it says 24-hour cure, this stuff cured in 15 minutes or so. Adding more than a drop of acrylic paint to color makes it harden faster and sometimes clump up.

Except for that, it does a perfect job to seal the water leakage of the toilet tank. The screw(s) of the tank has been rusted away and completely dropped out. I applied it as a layer/surface to cover the top of the hole of the screw. It adheres and sticks fine on the surface of the tank. Then wait about 2 days to let it dry, fill the water, and no leakage anymore.

I also needed to seal in a couple of pieces of glass on my door that has frosted glass held in with lead. It did the trick until I can get it professionally fixed after COVID-DAYS.

Other products that claim they are 100% silicone are not as durable. Some contain mineral spirits, petroleum products, or glycol products to be thinned or vaporize to cure with.

FAQ of Dap Silicone

Q: Will Dap Silicone work effectively with Vinyl, such as in a pool? I need to seal around underwater return line outlets.

A: Absolutely! This silicone sealant is 100% waterproof, so it will work well for sealing around underwater return line outlets in a pool. Just make sure it dries completely before adding water.

Q: Can Dap Silicone be used for making DIY silicone molds?

A: While you can try using this silicone sealant for DIY silicone molds, it is quite flexible after drying. If you’re looking to create firm and hard DIY items, this may not be the most suitable option.

Q: Can Dap Silicone be used to seal a plastic outdoor shed?

A: Yes, you can use this silicone sealant to seal a plastic outdoor shed. It has strong adhesion, which makes it suitable for such applications. However, keep in mind that it is only water-resistant, so if you want to rely solely on silicone for sealing, you may need additional protection.

Q: Have you tried using Dap Silicone for making decoden phone cases?

A: Yes, you can use this silicone sealant on concrete. The General Purpose version is even stronger than the Kitchen & Bath version for weatherproofing. It can also be used on marble, quartz, glass, metal, and wood.

Dap 18539 Kwik Seal Plus Kitchen and Bath All-Purpose Adhesive Caulk
The versatility of this caulk product is impressive. I used it to seal my 3 dots marker lights, and it worked like a charm. The end result was perfect, providing a reliable and long-lasting seal. I can confidently say that this product exceeded my expectations

In terms of functionality, this caulk product is top-notch. It is easy to use and dries quickly, which is a definite plus. As for its effectiveness against mold and mildew, I will need to wait and see. Nonetheless, I am optimistic about its ability to withstand such issues.

using DAP Kwik Seal Plus Sealant on bathtub
I can confidently say that it is my go-to solution for filling cracks and small holes that are exposed to water. Its clean and flawless appearance adds a touch of perfection to any surface it is applied.

It surpassed all my expectations, prompting me to go beyond my initial intentions. After successfully caulking the area I initially bought it for, I found myself getting carried away and caulking every other spot in the bathroom that could benefit from it. The bright color of the caulk gives a fresh look, and the application process was fairly easy. Cleanup was a breeze with just soap and water. Even after three weeks, the caulk looks as good as new.

But here’s an unexpected bonus: since I sealed all those small cracks, not a single bug has made its way into my bathroom. It seems that the tight seal created by the caulk keeps them out. I’m delighted that I went a little “caulk cRaZy” and chose this brand in particular.
