Common Questions
Can this product be used for a brick firepit?
I used it on a brick wall around my patio, but it didn't seem to handle high heat, and the company said it should be used in fireplaces and fire pits.
Is it a good idea to apply before it rains?
I use outdoor adhesive on patio steps when some loosen, but it's important to clean sand, dirt, etc off bricks before applying the glue.
How difficult is it to remove the old glue when this needs to be reapplied?
If the material is brick or stone or thin veneer type stone, I wouldn't attempt to remove it until the glue has cured.
Is it possible to use this on tiles to concrete bond?
We used this on a firepit for landscape stone and heavy tiles to replace old ones in a stone shower. This product has held well and had no problems on each application.
Is this product good for sealing a 6 mil vapor barrier to the concrete block walls inside a crawl space?
I'm not sure if this would damage the vapor barrier, but there are special glues for it.
