Use tape on both sides of joint prior to applying the self-leveling sealant if you want the job to turn out cleaner in the end.
@zweihander74652 ай бұрын
You mean apply tape ontop of the backer rod once its in the gap?
@Sloanmatthews2 ай бұрын
@@zweihander7465Apply tape, such as cement painters tape or tape able to stick to concrete (avoid duct tape) to create a straight line about 1/8 inch on both sides of the gap (edge). Apply sealant directly over backer rod filled joint , smooth if needed, remove tape carefully before it dries. Process is the same when caulking windows, bathtub, etc.

Use foam pipe insulation with backer rod inserted to make it solid. If the gap is huge, use different size pool noodles.

Twisting and doubling the backer rod is not a good solution. The rounded backer rod gives the sealant the proper profile to per form correctly . Also it needed to be wire brushed and primed. It also should be tooled both directions to insure a proper bond. I installed sealants professionally for 40 years and can’t remember how many times I have been called out to fix sealant a homeowner installed. It is not really difficult but there are basic things that need to be followed if you don’t want to replace the sealant every couple of years. With just a few improvements this would have been installed correctly. Get the right size backer rod, at least10-15 percent bigger than the joint. It has to be a very snug fit They make it all the way up to 4”.this is far more critical than most people think.As a professional if a tech rep from the manufacturer found the wrong size backer the warranty would be void. Wire brushing the sides of the joint is absolutely essential, we do it even on brand new concrete. And it only takes minutes. Finally every quality sealant ( like Sika) makes primers for their sealant and concrete. Use it. Just go to the manufacturer web site and find the data sheet for the sealant.Most sealants say something to the effect of “ no primer needed on most substrates” but if you take the time to read their product literature they all have primers and say to test adhesion first. Again one of the first things tech reps look for. Finally don’t use a water hose to clean the joint. The reason for not twisting or doubling the backer rod is that the optimum profile for sealant is an hourglass shape “) (“ Where the top and bottom of the diagram are the sides of the joint. Since the sealant is self leveling the top of the joint won’t be concave so it is critical that the bottom is.
@LaRod725 ай бұрын
I have the same issue as this guy. However, the joint between my concrete patio and foundation is about 6" deep and about 1.5" wide at the widest point. I've been seeing videos of guys putting sand at the bottom of deep joints to fill gaps and to raise the bottom for the backer rod. Is that the correct way to raise the bottom or is there a better method?
@genecarden7805 ай бұрын
@@LaRod72 it is not correct. The proper way to use backer rod is to buy the correct size that will compress a little and fit snuggly in the joint. There is absolutely no need for sand. If you need sand to keep the backer rod at the right depth the backer rod is too small and won’t function properly. Backer rod is available from 1/4”” that will fit in very small joints all the way up to 4” that will fit up to about 3 3/4” ( or slightly bigger) If you search out SofRod it is softer so that it compresses more easily and 1 size can fit a wider variety of joints than closed cell backer rod ,which is much harder to use in joints that vary in size. Think about putting sealant in vertical wall joints. Those are impossible to “fill” with sand to keep the backer rod at the proper depth.

A side note for inexperienced caulkers. Make sure when you’re caulking concrete that you rough up (score) the concrete where the caulk will be before applying the caulk. This will help the caulk bond to the concrete. If the concrete is smooth or slick, there’s a good chance the caulk will peel off.

Kathryn Willette. I’m 63, and my hubby is handicapped so I DIY as much as I can or am physically able. I feel I’m in pretty good shape and can bend and move about. Anyway, I have checked my windows which have a concrete mortar connection to the exterior stone wall. I just finished doing mortar repair around all the cracked stones and a gazillion small holes I found. We’ve battled drafts and bugs for too long and I was recently taught the solution. After the mortar on my home is caulked (I’ll be done today), I’ll use a waterproof and PAINTABLE silicone caulk by DAP. If you need to do the mortar repair, buy tube(s) of Sakrete Mortar Repair...with acrylic in it from Lowe’s in the building, lumber or masonry section at the PRO desk). Next, I have a large gap between the stone wall and the driveway slab and I’ve already bought my supplies. This video was a huge help for my confidence level! Good luck. Fixing your holes for drafts and bugs is a snap/easy. Let’s “git r dun!” Respectfully, Ange’

Hey Steven, tried to leave you a comment previously but have no idea where it was sent. Apparently not here lol. I’m a 44 year old woman who is at the very beginning of a long road to learning how to do proper home repairs and maintenance for the first time as I’m now on my own. Will you please let me know which type clear primer I should look for to buy in store? Also read in the comments that many people suggest “roughing up” the concrete. Does this mean a light sanding like you need to do with hard plastic before painting? Lastly, should I do both the roughing up and primer? Or is only one of these recommended? Sorry to ask you, especially so many questions, but this project will be my very first time attempting home repairs so I really want to make sure it’s done correctly.

Others provided tips such as scoring both sides of the gap, cleaning with a wire brush, and applying a clear primer for concrete to bind to the concrete flex sealant. And a few suggested sprinkling with sand after to make the smooth sealant blend in better.
