Customer Questions & Answers

can this be used on a deck of composite material? Looking to deter mildew.

can this be used on a deck of composite material? Looking to deter mildew.
Asked by: jmac
Hello Jmac, Thank you for your question. If water soaks in, then so will Micro-Seal. If Micro-Seal soaks in, then it will seal the surface and help protect against stains. If you perform a simple water test to determine if water will soak in, that will determine if Micro-Seal is right for that application. If you have any questions, let us know and we would be glad to assist. Thank You, Customer Service

Is this product breathable? looking to apply it to brick on a chimney and needs to repel water going in but allow to breath moisture out from the chimney's heat and to allow for expansion and contraction.
Asked by: Luis
Hello Luis, This product is breathable and will never trap moisture in the surface you apply it to. It is also "flexible" so the expansion/contraction you mentioned would not affect the coating. Let us know if you have questions. Thanks, Customer Service

Micro-Seal 1 gal. Ready to Use Multi Surface Penetrating Water Repellent is rated 4.2 out of 5 by 13.
Rated 5 out of 5 by from Works on the rain leaking from my stucco house The wind driven rain poured on my stucco wall of the house, patched every crack I could see and find but rain water still went through the insulation was very wet and water flew to carpet and mold growing to sheet rock and baseboard. Stucco guy said it has to redo stucco and estimated over $5000, and I couldn't afford. Then I was thinking to put flexseal from Lowes store but flexseal was bad and dripping a lot on the vertical stucco surface. Then I thought to spray rubber paint but found out that paint was not so thick. Then don't remember how I finally got to rainguard, and bought a $10 one gallon to try, it seemed work but still didn't completely stopped the leaking. So I came to Homedepot webpage and read carefully again, and decided to change to this model. Though it didn't say it can work on painted stucco actually old stucco paint, and one reviewer said it was only for new concrete, but it worked on old paint stucco house and stopped the rain leaking after 2 coats. I didn't power washed the stucco before the spray but it still worked. This is the first time I write a review because I m so excited and want to share my TRUE review so some people who have same issue can get a solution.

Rated 2 out of 5 by from New concrete only. I never saw this on a label, but this is not for older concrete. Sales rep told me it stopped working because my driveway was more than a few years old. They have other products, but this one might not be for you.

Rated 5 out of 5 by from Micro-Seal is terrific! This product is great. I pressure-washed my patio and let it dry. The Micro-seal went on easily with a garden sprayer, and was well absorbed into the concrete. My patio is stamped, stained concrete and Micro-seal revived the color, added some sheen (without making the patio slick or slippery), and has done a nice job of waterproofing the surface. I am very pleased. It covered a 12 x 25 patio with two coats. It looks like new.

Rated 5 out of 5 by from Excellent Product Excellent product with extremely easy application using a generic sprayer. Used it on the masonry on the front of the house and it clearly seals against the water, but the great thing is that it does not change the color tone and texture. It applies quickly and evenly and I plan to reapply this product at least once a year and expand use to some masonry walkways/patios in the yard.

Rated 5 out of 5 by from Easy and effective The product goes on easy and the effect is dramatic. Water beads on the brick instead of saturating. Hopefully it lasts for as long as advertised. I'm very pleased thus far.
