A: Yes you can use this to fill cracks behind mortar joints. It will work just fine.
by|Mar 12, 2019
A: I would not recommend that, mortar should be used for mortar joints. You can then seal the brick with a masonry sealant.

A: Sorry for the late response. Hope you had success. I believe it can. I used it to fill the gaps between my exterior walls and the slab on the inside of the house (poorly constructed semi tract home.) I then used acrylic caulking to seal it in. It is quite sturdy.

A: Yes, mold can grow on just about anything eventually
by|Oct 30, 2019
A: There is a possibility that it could hold mold since it can hold water.
by|Nov 20, 2018
A: It states "moisture repellent". I guess it depends if the area could get a lot of water regularly and is not in a heated space.

A: You would have to use a sealant on top of it. This is just a space filler. I used the pool crack sealant on top of the filler

A: Yes it's similar to the foam that comes with outdoor lighting. 3/8th inch is pretty thick so make sure it's what you need.

A: The caulk saver can be used outside to fill small gaps and openings before you apply caulk to seal.

Q:Can I use this product to fill an expansion joint with a 1/2" opening & about 1 1/2" depth around the outer perimeter of our pool, in which we also have to fill the top 1/2" of the opening with Deck O'Seal? Do you think we may need to put 2 layers of the 3/8" Caulk Saver to fill about 1" depth of the opening, before filling the top 1/2" with Deck O'Seal? Thank you.

A: No, this is not recommended for that use.
by|May 5, 2023
A: Yes but you may need a bigger size and it should not be seen, cover it with somthing to protect it.
by|May 5, 2023
A: The caulk is really for small gaps and openings in expansion joints. You may have too large an opening. I have seen 5/8" caulk saver.
by|Nov 26, 2018
A: I used it to fill concrete driveway and sidewalk compression joints. I used a flat head screwdriver to press it snuggly into the joint to an acceptable depth, significantly reducing the amount of caulk needed to fill the joint.
by|Oct 11, 2018
A: Usually gaps are not consistently the same size, so I've noticed that I need maybe a 3/8th and a 1/2 inch caulk saver. I stuff one or both as best I can then use a caulk or deck o seal.

Q:I'm installing my outlast laminate flooring and they told me i needed this where do i use this?
by|May 18, 2017
5 Answers
Answer This Question
A: Pergo outlast states to use” 3/8” OD PE foam” between the floor and the wall and on both sides of ant T joints. Outlast is “spillproof” so this foam should stop fluid from getting under the floor. Also you are instructed to seal the perimeter with 100% silicone sealer under any new kick boards, and at door jams to complete the installation. Funny pergo has none for sale on there web site.

A: It's used to fill gaps. Perhaps you need it at the very edge of your flooring against the wall
so the baseboard will be flush with the flooring?

A: Pergo outlast is “spillproff” they recommend a “3/8” PE foam” surrounding The perimeter of the floor between the wall and the floor. Then seal it, on top of the foam, with 100% silicone.. the foam and silicone should be used at all transitions as well. Any cut in at door jams only the silicone is advised unless you’re u can fit the foam in the space. The warranty is void without this treatment

A: You will be leaving a space between the wall and the flooring to allow expansion of the laminate flooring.
It is in this space where the caulk saver will go and then caulk on the top of the caulk saver. Caulk allows the flooring to expand and keep out any water that gets left on the flooring. For example, wet boots, pets accidents. Used all around the room perimeter.

Q:If I use this backer rod for a shower caulking, after caulking cured, water get in behind the caulking and the rod is soaked in constant water, what will happen to the rod? Will this affect the caulking?
by|Jan 18, 2017
3 Answers
Answer This Question
A: I would be more concerned that water is getting beneath the caulk. This could cause destructive water damage. Make sure the backer rod fits tightly in the gap and make doubly sure your caulk completely seals the gap.
by|Sep 7, 2019
A: It could cause mold growth being constantly water soaked.
by|May 4, 2023
A: The rod will get moldy over time but if the caulk seal is good, water will not get behind it
by|Oct 30, 2019
Q:Is it water resistant? Can I use it for shower caulking? The gas is between the tile wall and shower pan and there might be constant water there.

Answer This Question
A: This is to be used to fill in behind caulk to save on the amount of caulking used. It is not water proof.
by|May 4, 2023
A: Yes, it just needs to be caulked over well
by|Oct 30, 2019
A: yes, but you do have to caulk over it, which will be the real water proof/resistant material. If you're using it for something that you won't caulk, then the caulk saver may be water resistant, but water will still get past it.

Q:I caulked once before but it started leaking again. Gaps are about 3/8", do I need caulk saver to make it stop leaking for good?
by|Oct 9, 2016

Answer This Question
A: You probably have a laminate countertop. There may be a crack or problem area which is why you have a 3/8 inch gap. The sink should be wider than the sink opening, so there is no gap
You can try this caulk saver and then use a good caulk, but the counter seems to be the problem. That's a pretty wide gap around the sink. For a permanent solution, you may need a new countertop or sink. If your sink base can take it, maybe go one sink size up. Someone would need to cut the sink wider
by|Nov 11, 2017
A: Do not know if this will work for this. We have never tested for use around sinks.
