Can I use this to patch a 3" hole where firebrick crumbled and also to patch surrounding cracks? Is there a better product? Mortar?

This stuff worked great in that kind of application for me. If bricks or part of bricks are missing they must be replaced but mortar seams, even quite wide ones are safely and easily pathed with this stuff. Mix according to label instructions and you will be very pleased!

I believe it comes with something so you can patch it up....if not you could go to a store and find something to cover the hole and find some glue.

I used it to patch pits and cracks in garage cement. I made sure it did not need stirred up, but basically just trowrled it on and let it set up. Only a couple placed did I need to add a second coat to bring it to level. I had used it several years ago, around cement at the back door to the garage. It has held up to extreme temperature changes and traffic over it. It is for thinner cracks. They make a powder to which you do add water for deeper wider cracks.

Not no, but Heck NO! This stuff is for wood products. You might try a two-part epoxy such as Dev-con from B.E. Atlas.

Yes, I did that exact repair.You must do this in stages, as it will take more than one application, if a hole is involved.This formula drys to a hard finish, build it up by stages.

Yes because it won't last past 2 or 3 months. .. that's what I used it for. .. Definitely NOT worth it...Mine is now at the city dump with 4 holes in it. .. After the first 3 were patched, it wouldn't hold with the4 th patch

Not really. It's similar to duct tape. Best to use tape to cover crack. Then get some plaster, key that dry. Then paint.

I think it would work. Filling the crack is essential. You can apply more to make sure the crack is filled since irt binds well to that already there.

I don't believe this product will work for what you need. It is a high heat cement intended to fill small cracks in fireplace bricks & it works well for that purpose. I think you will have to provide the model # & manufacturer of your unit to obtain what you need. If you have a good local metal fabricator or fireplace/stove store near they might be able to help with your problem your problem.

A contrarian here. .. If I was filling a very narrow crack or shallow crack, I would use CA glue (red label, thin) . Anything else and I would use epoxy, you get more working time and I think a clearer matrix for the work. Inlay with with turquoise implies a larger void and I would think epoxy is easiest. There are 2 other viscosities CA glue that might work as well... medium and thick. .. yellow and green label for hot stuff.

I think it would not adhere well to bricks. Using double faced foam tape might be a solution.

I don't think I would use it for that purpose, I think replacing the pipe would be safer. I use it to seal cracks in the brick lining inside my fireplace. Guess you could contact the manufacturer to get their opinion.

Yes it can be used to fill holes in concrete. If the hole is less than 3/4 inch I think the liquid repair is preferred. The liquid does best to repair cracks.

I used bondo to repair a rotted floor sill on a shed. It is essentially body filler and since you mix small amounts with epoxy for each application using it for a school project as you suggest probably would be difficult and much harder than you probably need. I would use modeling clay.

I used this product mainly to repair the sides, but also used it to patch a few cracks on the bottom. Was more challenging since it was harder to thoroughly clean that surface and remove all ash and loose pieces before applying, but it seems to be holding well.

I used it for a bulls eye chip and it worked well. I don't know if it will fix a crack but think it probably will not. I would try it as an experiment before getting a new winshield.

As a repair of a small hole, yes. If there is a lot of stress on the repair, it may fail. Make sure you remove the finish and apply the epoxy to the bare surface.
