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,

New Construction Walls

I bought and applied the deco 20 to my new construction walls. I used (1) 5 gallon bucket and sprayed walls, the difference between the sprayed walls and retaining wall which is not sprayed is just like the video spraying the wall with water. The rain water beeds up and runs off. Very impressed with this product and will use it again. Zach Bryant

Rain Causing Interior Moisture

Rating:
Pros:
Cons:
We have a block building and two of our walls had moisture inside when it rains hard. We were told Deco 20 Clear was the best product. We contracted an outside firm to spray the exterior walls with this Deco 20. Since then we've not had any issues with moisture and it's rained hard several times. This is an excellent product that we will be including in our MRO plan for our other facilities. We appreciate your technical help and fine product.
