Sila-Tek™ 3500

Easy to use

I put the stuff over the concrete hardener. It went on pretty easy. I just had to continually broom it out to keep from puddling. We have not had any rain here yet since I applied it, so I will have to edit my review to see how it works in action.

Does the job

Easy to work with and leaves a nice gloss shield I wasn’t expecting. Wish I would have stoped here. Unfortunately, I topped this 7 days later with 8500 and regret it. Left a ghastly white coating on top of the densifier finish in a new concrete shower pan.

Is it working?

I have no idea how to tell if this is actually working. I'm just going to assume it is. I got it because I was told it would make the sealer work better. Hopefully it does. Overall, it was easy to use and dried nice and clear as advertised. If you get any puddles it will leave a white salty looking crust on top of the concrete that doesn't come off easily. I was really worried about messing up and having that happen everywhere, but it turned out okay. We did get a little bit of it right along a block wall on our patio but I'm not too worried about it. As long as you brush out all the puddles it should be good.
