Customer Questions & Answers

Can this be used for swimming pool deck expansion joint?

I would like to use this between my swimming pool coping and the concrete decking.
Asked by: milyno
Yes it can. If it "pulls away" than any product used would have pulled away. Deck-o-seal is not better and it costs more.

Hello and thank you for your question. As per the response from The Home Depot below, "Unfortunately, home depot does not ship outside of the United States." Thank you for your interest in Sika products!

Do you have a 29 oz. Sandstone Non-Self-Leveling sealant for driveway joints that are on a slight incline?

I have used the Sandstone Self-Leveling sealant on several of my driveway joints that have pretty much no slope to them. However, I have many joints that are on a slight slope and I am concerned that the self-leveling sealant would just run to the lowest point, pool up and spill out.

The Sika brand will work fine. The Quickrete brand will run and pool up very bad.

Can this product be painted over in a concrete driveway application?

Asked by: buckethead
You wouldn't want to. It's rubbery and would be very expensive and hard to work with in such an application. I doubt it would hold up under car tires either. Would probably start to shred. And look filthy quickly.

29 fl. oz. Sandstone Self-Leveling Sealant is rated 3.5 out of 5 by 13.
Rated 4 out of 5 by from garage floor project Works as described. The product done a good job of self leveling. Works best if you can make one pass rather than multiple passes.

Rated 5 out of 5 by from Great Product! Really seals large horizontal gaps! To use this product, it is all about the preparation. 1. Utilize Youtube to review the proper application of this product. Read the instructions. 2. Make sure to clean out and backfill all of the gaps that this product will be filling. 3. Use the 3/4" grey foam tubing or sand to fill the gaps. (Note: You do not want to see any holes in the gap or the product (after backfilling) will find its way into them. The final result will show a funnel hole after the product sets up (dries).) 4. Cut the tip off the product and make sure to poke a hole inside the tips to break the seal that will allow the product to flow. 5. Be careful not to get this liquid rubberized product onto your hands. Hard to clean off hands. 6. Be careful to aim the tip into the gap with squeezing the caulk gun trigger. Keep the tip aligned with the concrete gap at all times. Do not allow the product to spill onto the concrete outside the gap. It will be difficult to clean off. 7. Apply the product to small area initially to get a feel for how the product self levels. You will be able to determine the correct amount of sealant after doing this step. 8. Once the sealant is applied into the gap, go back an add more sealant as necessary while still wet. 9. Once the product dries or sets-up, you can go back to the gaps to add more sealant but it will be slightly noticeable after the job is complete. 10. Good Luck! :) I hope the steps above are helpful and not confusing.

Rated 5 out of 5 by from Great at self leveling Have used multiple times. Highly recommend sandstone color over gray. Blends better once dirtied a bit. It's warmer, the gray is very cold and bright. Looks fantasic if you sprinkle sand on while still went, in an even sweeping motion from a cup. Very forgiving. Recommend sand as backer, better free float for bottom of sealant for better stretch in extreme weather.

Rated 5 out of 5 by from Excellent Product! Perfect for sealing concrete seams in driveways and sidewalks. Durable, flexible, excellent adhesion, and looks great vs those old joint boards in concrete seams. No more weeds growing out of your driveway! Dries to a hard yet flexible rubber type material. If you notice concrete seams in city sidewalks and parking lots this is what you will often see used. Long lasting and very durable. Seals the moisture from getting thru seams and damaging concrete over time.

Rated 3 out of 5 by from Pretty good, but can have color inconsistencies The product was easy to use and self leveled nicely and looked and felt nice once cured. I used it to caulk the gap around our pool coping and concrete deck. It took 10 tubes or so. Some of the tubes had some white splotches that came out that required stirring to mix up the color. Even after mixing, it still wasn't perfect. If I were a contractor, I'd be sweating bullets with a picky homeowner who'd tell me to redo it.

Rated 1 out of 5 by from Color not fully mixed Will never use this again. Every tube started fine but approx halfway through the color was not mixed I would get white and sandstone caulk - as a result my pool caulk looks terrible, will likely have to remove and re caulk with a better product.

Rated 5 out of 5 by from Excellent product! Having used Sika brands for Military applications, I had a great feeling this stuff would be superior. It is! For large, or deep cracks, you MUST fill the void first! If you don't, and since the product flows, it will sink down to the bottom of the crack, causing you to go over the crack many, many times. Use sand, or crushed rock, both sold at The Home Depot to fill voids. Use a screwdriver to work what you use to fill the void into the cracks too. You can even tap the void filler down and pack it. After the void is filled, then use the product. The product does flow nicely, this is what you want and is certainly NOT a bad thing. Flow also means is self levels, giving nice even smooth results from end to end, or side to side in the crack. The gray is bright, I've not used the sandstone color myself, but to me, seeing a gray crack, is better then a black crack line in my driveway. I've used 5 tubes of it on my drive and it dries quickly and stays pliable.(hide)

Rated 5 out of 5 by from Easy to Use - Prep is important As others have written, you really need to do your prep work before using a self leveling crack filler like this. You must clean everything and then truly fill in all the potential leakage paths under the crack. In my application, I sealed up the expansion joint area between a concrete slab and the stucco on the side of my home. The expansion joint was fibrous so I caulked first down in the crack to make sure the Silkaflex wouldn't leak down below and go to waste. When the job was completely done, it looked great. While wet, the cleanup was easy, a was able to wipe up "mistakes" with a rag and then get rid of the residue with paint thinner. As someone else has written, the folks at home depot are a little too rough with this stuff in transit or in the store. There were several damaged tubes in stock at the store. They had various kinds of leaks that had dried. I had to pick through the stock to find four clean, un-damaged tubes of product. In fact, there were so many trashed tubes in my local HD that they can't possibly make money on this product.
