Customer Questions & Answers

Can it be painted

Asked by: Veg
Hello and thank you for your question. This protect can be painted after a full cure. A full cure is reached at 4 to 7 days, depending on temperature and humidity levels. The higher the humidity, the faster the cure.

I have slate stairs on my front entrance. There is a large gap (1/2 to 3/4") between the riser and the step. What product should I use to close it?

The steps are on the north side of the house and get little of no sun most of the year. How should I close up the opening? Should I use a filler first?
Asked by: john
Hello and thank you for your question. The width is not an issue but the depth of the joint should not exceed a 1/2". You can control the depth by using Sika Backer Rod. You can follow by using by using Sikaflex.

Rated 5 out of 5 by from This is equivelent to Kerdi-Fix I ran out of Kerdi-Fix and couldn't wait the 2-3 days shipping on another bottle where I'm located. Kerdi-Fix is used to bond drains/etc. to Kerdi 100% waterproof membrane (GREAT stuff and been around for 25 years). After an hour of research, it turns out their MSD sheets are nearly identical (Kerdi-Fix is a polyurethane sealant with no significant additives just like Sikaflex), and they look, smell and flow almost identical. Boo to Schluter for charging almost 5x for generic polyurethane sealant... Yay to Sikaflex for making the equivalent almost 5x cheaper. Used this in a shower alongside Kerdi-Fix; the drain bonds are identical in every way you can tell. Great product, great value! I'll be using this from now on in place of Kerdi-Fix.

Rated 5 out of 5 by from I've used sika in commercial and residential The company I work for uses this product on ALL of our plywood balcony decks and commercial/restaurant waterproofing jobs. This is the only caulk that seals wall flashings, door pans, drains, and makes fantastic small, pre-existing deck repairs (before coating the deck again). The decking company has been in business for more than 20 years, and Sika has definitely been apart of the backbone of what is helping move the company along and the decks remain strong. We use the small 10 oz tubes and the sausages. If you need to seal a window, door pan, door frame, whatever- this is the only product I use at work and at home. Yes, it's a little pricey, but premium quality products come at larger prices. Pay the extra for this product, you won't regret it. And if you don't, I promise you will regret it later, been there and done that. :-(

Rated 5 out of 5 by from I settled on this for a basement remodeling project after testing out lots of sealants This worked very well for all my purposes: - Sealing air gaps between exterior sheathing (plywood) and studs. - Sealing gaps between polyiso insulation and concrete floor. - Sealing between polyiso and joists. It has adhesive-like qualities. It sticks to everything. It goes on evenly, spreads well and it can be tooled if you get to it quickly. It is better than silicone without a doubt.
