Customer Questions & Answers

Once this product cures, can I paint it?

Asked by: Wendy
Hello and thank you for your question. Yes it can be painted after a full cure, 5 to 7 days depending on humidity levels. The higher the humidity, the faster the cure.

Can I use Sikaflex Mortar Fix to repair mortar in rock garden walls? If not, is there a better product?

Asked by: Repairer
Depends on the level of fix required. Mortar fix isn't made for holding structural support, it's more of a cosmetic fix. Figure out the root cause of the original settling problem or mortar cracking. If that isn't corrected then the mortar fix probably won't solve the issue long term. If you're just looking to maintain or clean up the rock garden wall it will do the job. However, if you need structural support for the wall, I'd do it right with either re-grout of tuckpointing repair. If you do use the mortar fix, you'll need to match the existing grout color, so try to find a larg(er) piece to take and color match the paint.

Does this product adhere to both wood and masonry?

My project is an exterior brick wall with a cedar plank designed throughout the brick. The cedar and brick has separated and have small gaps allowing rainwater to penetrate the wall. Is this product the correct application to seal the gap between the brick and the wood?
Asked by: KJ
Hello and thank you for your question. Yes it can bond to both. Both substrates must be clean and sound before the application can begin.

10.1 fl. oz. Mortar Fix is rated 3.1 out of 5 by 12.

Most of the negative reviews focus on the color rather than the performance of the product. The reason I used this stuff was to strengthen certain spots of my brick steps (mortar on my steps over the years has deteriorated due to seasonal freezing and thawing cycles) so the mail delivery person and friends coming over won't step on a wobbly brick and hurt themselves. To that extent, this product worked fine for me. No, it doesn't match the color of mortar (it's a bright grey color) because IT'S NOT MORTAR. In my opinion Sikaflex Mortar Fix did a great job of strengthening my steps until I can research local contractors that can tuck point or replace my steps entirely. So, in my experience this product did what the manufacturer said it would do. Yes, it's gooey and sticky but home repair is inherently messy. Just proceed slowly, squeeze the caulk gun slowly so as to control your product spread and you should be fine. As one reviewer said, use a heavy duty caulk gun, this stuff is thick and a flimsy caulk gun will make the job harder. I hope this review helps someone!

Rated 5 out of 5 by from It's a fine professional product It works very well. When I say it is a professional product I mean it works very well when applied properly. Tape areas you don't want to stain, wear plastic gloves, apply a consistent bead, use backer rod when required. It does not apply as easily as silicon. It is meant for a different application. And yes, it cannot magically match every shade of mortar known to man.

Rated 2 out of 5 by from Not the best product to use I had used another product yesterday and ran a little short. I decided to try this product. As can be seen in the photo the color isn't close. It is very sticky. It is the consistency of cake frosting. I used a tuck pointing tool to smooth the material by shimming the tool back and forth to smooth out the product. It's is so thick, it does stay on a vertical surface. See photo. I got on line prior to the purchase to find out the maximum width and depth. Coundn't find it. No mention on the tube. It refer's you to the web site which is very poor for finding info. This should be on the tube. I would not use this product for this use again

Rated 1 out of 5 by from Horrible product all around! Like one reviewer stated, the finished product doesn't look like or even resemble the color of any concrete or mortar I have worked with. It looks like light grey plastic! While color is one thing, the worst part is that this stuff comes out of the tube in a gummy stringy mess that is impossible to apply tool and smooth over with a wet finger or even a floating instrument without dragging it around into what looks like a mess of used bubble gum. And finally, this stuff doesn't become tack free until at least 24 hours later (even though the tube states 6 hours!). To add insult to injury, get this- The caulk starts to BUBBLE in certain areas. The manufacturer would probably say that moisture was present when I applied it, but I applied it to a bone dry surface. I just think that the uncured caulk underneath blisters or pushes the top skimmed layer up while it's drying. Ripping this stuff out is no picnic either. It is messier than any caulk I've ever used!!!!! What a HUGE waste of money!

Rated 2 out of 5 by from This product works too well I purchased this product to reepair the mortar on a chimney. each line I caulked and spread in left a small residue on thee bricks and was impossiple to remove. It took me ten minutes to work a 4 foot mortar joint which was too time consuming. Once on a brick it will not come off.

Rated 5 out of 5 by from excellen! This is the best mortar filler I have used so far trying at least 3 other cheaper products from HD. It needs extra attention while applying but after it dries it gives very reliable bound that has a heavy duty rubber like look and feel. I found that the best way to blend it in and clean it from surrounding bricks is to use non-woven quick strip disc on a drill that makes it possible to grind it down to a desired depth and texture.

Rated 5 out of 5 by from Great product, follow the directions This stuff is great--don't listen to the negative reviews here. Yes, you should wear gloves. Yes, this product comes in one color which does not magically match the color of your house. Yes, it's thick and gooey. All that being said it does the job well. So far the stuff I put on last year is holding like i put it on yesterday. Your caulk gun should be pretty heavy duty (like an $8 gun instead of a $2 gun.) I use a tool for caulk to help work it in the crack, sometimes a small metal tuck-pointing tool.

Rated 1 out of 5 by from Don't use if you want something that looks like mortar We recently had some work done at our house and the contractor used this product to fill a groove he cut in the mortar of our brick front walk to run an electric wire through. The product doesn't look like mortar and doesn't match the color of the mortar.
