CRL 33S Clear Silicone Sealant

Stays clear and does not yellow. Like everything else, when used in a shower surround maintenance cleaning helps keep it looking great. I did not have this product when I did my other shower, and the top of the line big box 10 year no yellow/mold bathroom caulk claim is bogus, didn't last 2. The good part was that the big box caulk came off easily and took no time to replace. I have had this caulk in another bathroom for 4 years and it is as clear as ever, with zero mold. Tooling was a bit harder with this tube than I remembered, but this caulk has really great adhesion, but it looks really good for much longer than any other caulk I have used. I used to have to go to the local glass installers to purchase, and for a premium price, but found it on Amazon. This is really good caulk, but with any caulk you may need to use a primer on certain surfaces. For fiberglass surround and polished nickle aluminum it worked just fine without the primer. Just be careful not to feather out too thin on the edges (just like all caulks) and you will be very happy.

This CRL is what the local RV place uses.. Works awesome

The best caulk I have worked with during our bathroom renovations. Super clear and very easy to work with.

Very good adhesion.

Best silicone ive ever used

Best clear sealant for bath shower glass. Long lasting and durable. Professional grade. Nothing at a hardware store will beat this product. Very clear in comparison to regular silicon. A bit expensive, but worth it.

Worked great ….so far it’s been a few months.

This is fine - it worked - it is translucent (not transparent) when it solidifies which was fine for me.

Great holding power and quick to cure. Used to seal an under counter sink that dropped. No issues after two months so far!
