Does this product come in a darker shade of gray, or brown? It appears almost white.

My driveway has a slight slope to the curb. Can I use this product, or does the joint have to be level?

Asked by: Badger
The consistency is like a milkshake. If there is enough room to create a level surface within the crack that's fine, but do NOT expect it to solidify at an angle. It's called "self leveling" & it's aptly named.

can this product be used between 2 indoor slabs?

having enclosed part of the concrete porch and it is now 'inside' , I want to seal the old joint between the house concrete slab and the old/now inside concrete porch before I put the flooring in place. In reading one expansion joint sealant I have for my driveway the VOC's are quite prevalent and says use in areas of plenty of air exchange..... so what I am looking for is a self leveling product for inside so I don't have to leave the house open all day.... so are there VOC's with this product that stipulate it being used outdoors...if this cannot be used inside , what self leveling mat'l is available with low VOC's? Many thanks
Asked by: pluf2

3.0 Advanced Self-Leveling Concrete Sealant is rated 3.5 out of 5 by 23.
Rated 5 out of 5 by from conditionally recommended You will hate it when it run away into crack not prep plugged by backer rod. Love it if you did. Find a day you can open the window or door long enough to let fumes eacape after application in basement or indoor. Math didnot favorably estimate consumption. Actual consumption was 1 oz per foot length crack 1/16" wide x 1/4" deep.

Rated 1 out of 5 by from This stuff has the viscosity of oatmeal and only a little self leveling capability. I was sold on... This stuff has the viscosity of oatmeal and only a little self leveling capability. I was sold on self leveling caulk watching a video of a guy going back along his line and adding more where it was a little low and watching it smooth itself out. Not with this stuff. As you can see in the picture, I added a little back on my line and the puddle is still there. To the right is where I smoothed it with my wet finger. And can you smooth it with a wet finger? Not easily. It sticks to your wet finger like glue. Also, the color is "gray". Does it look gray in the photo? Off white at best. Either this stuff is inferior or their quality control is inferior. I used a $7.50 tube on 6 feet of contraction gap, using a 3/8" backing rod, for results like those in the photo. Will use the $2.50 regular siliconized acrylic in the future.

Rated 5 out of 5 by from really good stuff This is excellent crack repair. Now you can't have huge cracks, they will swallow the tube up. If your crack is big you need filler rod to take up space then a small covering with this and it's sealed. Most cracks you just put a small bead over it and it self levels over crack and done. 24 hours later and try to get it up. Cars, pressure washers don't hurt anything. Also this is flexible for those freeze thaw cycles. Yes it is expensive I like to see at $ 5.00 a tube.

Rated 5 out of 5 by from Great product... Make sure to read the directions. As noted by others, a single tube may not go too far! One tube covered two expansion joints in my sidewalk. I did use filler foam to reduce the depth, but still wanted enough sealant that it would not be too thin & subsequently deteriorate too quickly. It took a few days to firm up, but was not sticky to the touch after the first day. I suppose if you apply in cold or humid weather it could take much longer. The color is a bit too light for my 30 yr old sidewalk. Would prefer a darker gray. The color difference is far more pronounced after it rains.

Rated 5 out of 5 by from Great sealant and made the job quick and easy Used this product to seal cracks in a concrete water fountain. Consistency and ability to spread and fill the cracks was spot on. Excellent product and will be using DAP products for other household projects in the future.

Rated 5 out of 5 by from Great crack filler, easy to apply I had cracks after ten years where cement met my building. Water could get in and freeze, making problems. This stuff really fills the cracks, doesn't go far if cracks are big. It would be best to find a rope calk for very large cracks to preliminary fill large areas, applying this material on top. It does everything it says it will do, is self leveling, and makes a good seal. I am looking forward to seeing how long this material lasts, previous similar material broke down after about five winters, I believe this to be a superior material based on my limited caulking experience. I have worked for contractors in the past, there is quite a bit of difference in caulk quality. It didn't take long for me to use up over $700 worth of this stuff, but if it does its job that is cheap compared to damaged cement or foundations. I bought a Milwaulkee power caulk gun that does a great job using this material, saves a lot of finger power for a big job, and does it easier since it not only stops when you quit the trigger, it also backs up a bit so there is no drip.
