Concrete Driveway

Rating:
Pros:
Cons:
We sprayed Deco 20 on our driveway about 4 years ago and noticed this summer the concrete looked wet or darker. I was hoping this product would have lasted 6 or 7 years but I was informed by Mark their salesman that driveways take a beating with foot and car traffic. We ordered 2 more pails and after powerwashing and putting on Deco it's beading more and isn't showing wet look after it rains. Yes I am recommending this product.

Hello,

I am having dampness in my basement and garage. In the past I have used DryLock and Thoroseal and had TERRIBLE results with both. Within a few weeks it would peel and moisture would seep through. I wish I would have know about Deco 20 Sealer months ago !!



Thanks

Deco 20 for Damp Basement

Rating:
Pros:
Cons:
Good morning,



I would like some information on sealers for my basement. The basement is all underground with 1 window well and the walls are concrete block. After a heavy rain, the blocks look damp and it always seems to have a “basement” smell. I’m not planning on totally finishing the basement…drywall, carpet, etc….just want it to be a nicer area for the grandkids to play without hearing “maw, it smells down here”!



Thank you,

Sandy Merklinger



Hi Mark,



I was very satisfied with the product. It also does not have that musty smell any more.



I had applied paint to the block after the Deco.



Thank you,

Exceeded Expectations

Austin & Mark,



Yes you met and exceeded my expectations. I received it in one day and I appreciate your fast service.



I just had the basement walls replaced and waterproofed. I wanted the same sealer that worked so well in stopping the leaks on the original walls. My concern was not so much for water intrusion since the waterproofing on the new walls is elastomeric versus the tar that the builder used in 2015. I also wanted a sealer that I can paint over for additional protection.



The Deco 20 sealer applied quickly using the sprayer type that Mark recommended. I only applied one coat and used the entire can. I avoided the plastic pipes as instructed. The cleanup of the sprayer was easy. I had no problem with odor as advertised.



I would rate the Deco 20 sealer a 5 and I would rate the customer service a 5.



I did recommend your product to the engineers and the insurance adjustors that visited and also to the masonry contractor that replaced the walls. I was so impressed with the Deco 20 performance that I keep a photo of the can that was used by the original sealing contractor when he visited to stop the leaks caused by his tar waterproofing.



Thanks for following up.

Impressive Deco 20 Results

Mark, I am so impressed with the product. We applied it after digging down to the footers. We had to let that last block dry out while we sprayed the entire 1344 sq ft of block. It was like magic. That material was so easy to apply. Typically in the area where my home is that I am building, the heavy wet dew would make the walls so wet. The morning after we sprayed it, we went outside and nothing, absolutely nothing was wet. My brother in law is an electrical contractor. He never saw a product like this before and was extremely impressed. We could not stop talking about how water beads up and rolls right off of the treated block.



I know I will be painting over the block probably in the fall but I was so glad to get this part of the foundation completed.



Again, amazing product and so so so satisfied with the results.



Thank you

Catherine Saldutti.
