Caulk – Choosing “the right stuff”

Not long ago I made a dramatic change. I decided to stop buying cheap white caulk.

My previous thought process was that if you can’t see the difference, the difference isn’t there. Well…I found out that’s not true.

Enter “Sashco” https://www.sashco.com/products/lexel/

Sashco makes LEXEL clear. This is an amazing clear “caulk.” When applied correctly, it becomes almost invisible and is ultra durable. It’s sticky before curing and you need mineral spirits to clean up if you make a mess.

Sashco also makes the “big stretch” this is caulk that can stretch seemingly forever. It eliminates the follow up on gaps that reappear after every major seasonal change.

And… keracaulk from Mapei. http://www.mapeihome.com/keracaulk-u

Recently grout began breaking away in my master bathroom. There are all sorts of fancy (expensive) solutions these days to isolate the tile from the sub-floor such as the Schluter Ditra system. https://www.schluter.com/schluter-us/en_US/Membranes/Uncoupling-(DITRA)/Schluter%C2%AE-DITRA-&-DITRA-XL/p/DITRA. If I were installing a brand new bathroom, I’d use a Schluter system regardless of price.

But what if your tile is already down and grouted? Mapei sanded keracaluk comes in a variety of colors that look identical to grout but flexes with the movement of the sub-floor. I removed the offending grout and re-caulked with Mapei and zero issues and perfect match. I love this stuff. It looks great, goes on smooth, and is super durable. I’m now using it between tile & tubs too where i used to have to re-caulk every few years.

More tips:

Get a quality caulk gun. Spend twenty dollars. Your job will go faster and your result will be way better. Smooth consistent application and even pressure is what it is all about. If you are fighting with a three dollar applicator and your forearms are shaking from muscle fatigue your finished product is guaranteed to look terrible.

The big box stores now sell these products. You don’t have to go to special stores to get them! You probably just haven’t been looking for them or dismissed them while looking for cheap white caulk!
