2013-05-30PATRICK TAYLOR: For a half inch crack and it is FLAT..you could fill it all the way up..other times I have heard of a foam material(to help take up the space..shove it down the crack and apply sikaflex over until it is water tight..each year..it may move..more sikafles.
2013-04-13BRUCE E asked: Can I use Sikaflex 1A to caulk where the shower wall meets the shower floor if I allow it to cure for seven days prior to use?
+Expand Answers
2013-04-16GREG SCHAMERLOH: I would say yes. I used this product in my basement along an exterior wall where I had some water seepage. (where floor meets wall) I used a blow dryer to dry the damp area before application. Actually, the water was seeping when I applied the sealant. Then, used the dryer for another minute or so after application. Worked like a charm. Been half year....no leaking.
2013-04-17PATRICK TAYLOR: I used it to caulk CEMENT cracks to keep a driveway from soaking up more water and putting pressure on the retaining wall.....I know boat people use it a lot. I would try it for your application..it dries fast and is very malleable....

2013-02-06MIKE MEARA: Absolutely. You are not going to find a better exterior sealant for the cost.
It's a bit messier than most of the products off the shelf, but it's worth it.
Good luck!

2012-10-04JULIAN PLOWRIGHT: NO! Sikaflex 1A is only a caulking compound, it do not have the adhesive qualities for mounting a boat motor. Boat motors need solid, secure, mounting to wood/fiberglass, or metal. suggest you check with your local boat yard.

Comments about Sikaflex 1A 1-part Polyurethane Elastomeric Sealant / Adhesive:
I used Sikaflex 1A to fill and seal 1/8" gaps between mahogany deck planks. A respected local Chris Craft restorer recommended it based on years of successful experience. It works the same way as all single part Urethane caulks, so it's messy and requires careful masking and application. The good news it is apparently the same formula as the marine designated caulks but it costs [$] a cartridge instead of $20. It comes in black, dark mahogany and one or two other colors.

I used on concrete cracks in my garage and it worked well keeping ground water out. Also used to gap on cement steps to wooden kick plate and worked better than any other previous products I have used.

Comments about Sikaflex 1A 1-part Polyurethane Elastomeric Sealant / Adhesive:
You should be selling a ton of this stuff in very wet Seattle. Every seam and joint seems to be leaking due to unseasonal rain and runoff. My builder had to search to help me find the product. Not sure if anyone local carries it.
