## Description

DAP Elastopatch Smooth Flexible Patching Compound is a high performance elastomeric spackling compound that eliminates reoccurring cracks by providing a permanently flexible fill. Excellent for use on smooth surfaces including masonry, brick, plaster, drywall or any surface requiring a permanently flexible seal. Spackle has superior paintability - won't flash paint and is NOT sandable. Wall patch can be used on interior and exterior surfaces.

Review: Magic. Works as advertised.
Review: I know some folks have given this a bad review because they say it can't be sanded. Even the vendor states that this is not sandable. I read a review where one person said it sanded easily. Likely a fake review as this stuff does not sand. I use this to patch holes in areas that I don't need a super clean look such as in the garage. Recently the lower part of a panel in my garage that goes into my crawl space got damaged. It was about a six inch wide, one inch high hole. That is a fairly large hole. This is pretty thick and I first tried to fill the hole with a Bondo spreader with just this product and after a couple minutes it would start to sag, exposing the hole again. I quickly grabbed some fiberglass mesh drywall tape put it over the hole with the ElastoPatch still sagging, then used my Bondo spreader again moving the ElastoPatch back over the hole now covered with the fiberglass mesh tape and it held firmly. After letting it completely dry it looks great. As long as you spread this stuff and leave it still it does dry to a nice clean smooth surface. Some have claimed that it shrinks, but I have never had that problem. Just be sure you use it over a clean surface as it won't stick to dirty, oily surfaces.

## Questions & Answers

**Q: Can you walk on it ?  I need something to skim-patch a few low spots where water lays on a waterproofed stairway. Plan 2-part decking top-coat . Thx!**
A: Yes. Since it's flexible and still strong when dry, I used it to cover up cracks after our patio and pool deck settled.  Then painted over when it was dry.
It dries in what ever shape you apply it, so make sure it's smooth or however you want it because it will stay that way.

**Q: what color is it?**
A: Sorry it took me so long to answer. White or just slightly off-white. Looks like regular white patch. It is a little harder to work with than regular patch, however the finish is very nice looking. Better than regular. After my experience using and finish this summer I will not go back to plain filler/patch material.

**Q: Can I use this product to air seal at the rim joist in the basement? Normally people would recommend using Great stuff spray foam.**
A: NO...THIS IS MORE A PATCH MATERIAL...

**Q: Can I use on a stucco wall to it make it a smooth finish instead of bumpy so I can apply wallpaper. It was an exterior wall that is now an inside wall**
A: Google says you can use this flexible patch on stucco. DAP also makes a product designed for stucco.

*by K***G on 28 April 2025*

I bought this to seal persistent large cracks. It's quite easy to apply. Adhesion to surface is acceptable after 24hr. The setback is the long drying time. After 8hr, coating is still soft though tack free. For tropical climate where rain is unpredictable, it makes usage tedious. If it rains within 5hr of application, performance may be compromised. Should have a quick drying version.
