Review: This a a great quality sealant! Great value kit. - A very good kit. I bought bigger tips for using on my old metal building roof. It had nails with lead washers holding the tin down and they are in tough shape and leaked like crazy. I make the hole on the end a little bit bigger than the fastener and put a dollop over every fastener with no mess or tooling, about the size of a hersheys kiss. It worked very well and sealed everything perfectly. I did a 40' x 60' roof with 5 tubes. Great value! Shel - Northern Minnesota USA.
Review: Well made easy to use - Smooth action easy to load and reload, easy squeeze grip action. 20 oz tubes are great for the bigger jobs

## Questions & Answers

**Q: Can this be used for backer board seams when prepping a wall for tile in a shower?**
A: I wouldn't recommend it as the backer board is porous and the Sika is totally waterproof...

**Q: Does this work the same as GoBoard sealant for waterproofing tile backer board? Looks like the same ingredients, but a lot less cost.**
A: I am not sure about that but I’ve used this for gutter joints and to seal up the concrete around the base of pole barn.

**Q: Can it be used in wet conditions? How much curing time does it take before it’s rainproof?**
A: It is made for wet conditions, but only AFTER it is applied and cured. As far as curing time, 24 hours and it's ready for paint, another few days and it's fully cured. And yes, this stuff is waterproof. It's made for pool deck caulking.
I've been using Sika 1a for years. I installed 14 windows in a home remodel with no screws. These were in a brick opening so there was nothing to screw it to. I will be securing after the interior trim is done.
Hope this helps.

**Q: Is this product self leveling ?**
A: No, this is not self-leveling.

Smooth action easy to load and reload, easy squeeze grip action. 20 oz tubes are great for the bigger jobs

### ⭐⭐⭐⭐⭐ Sikaflex 1a
*by S***S on April 29, 2025*

This stuff is great and easy to work with. I'd even go as far to say it is an esoteric product contractors don't want you to know about. I'm using it to seal up a brick basement wall.
