## Questions & Answers

**Q: I see a tube will make 99'xd1/8" beads but how much is recommended between each fire brick? I am building a fire bit and wonna to know how much i need**
A: I would not use a masonry mix.  I have refractory shapes inside my outdoor pit and the stone around and on top was mortared together using standard mortar.  It has cracked over the years (lasted maybe 4 years) and I'm in the process of replacing the joints and adhering the brick back together.  I am using this to fill in the larger cracks and I used Rutland 610 Refractory Cement to bond the stone to the refractory shapes.  Going this route is your best bet.  You could just use the Rutland 610 Refractory Cement with a 1/16" dip and the bond will work.

**Q: can it be painted with the Rutland 1200 * stove paint**
A: No, it's specifically for a fireplace and no other uses and is not paintable

**Q: Does this work with outdoor fire pits? Like in between the cracks of the brick.**
A: I'm not an expert, however, I believe it will work.

**Q: Will this adhere to previously installed Fire Block?**
A: As long as the place you're applying it to is free of debris, this should stick well. It is a thick consistency, so it doesn't really run or sag. I recommend having a small putty knife handy for spreading.

Easy to apply. Works very welk.

### ⭐⭐⭐⭐⭐ Works well
*by H***R on November 24, 2025*

Worked great on my brick chimneys mortar. Saved a lot of work. Dried a very light tan [buff] color, looks nice.

### ⭐⭐⭐⭐⭐ Rutland products work great for me every time
*by M***M on January 12, 2018*

I used it to fix hairline cracks, larger cracks and to coat part of the bottom of a crumbling prefab firebox. See photos. Simple 1 hour maintenance task that you will be glad you did for safety. Not a super neat job but very functional. I did this years ago - worked great - Rutland is great - but it was time for another application (the previous mortar is gray if you can see it) This time I used buff. Should have tried white. Oh well. 0- Follow all the instructions on the tube. 1- Tools: Vacuum, Caulk gun, 1” putty knife, 6” putty knife. If all you are fixing are cracks, you do not need the 6”. I also recommend a bright light and reading glasses. 2- Scrape to loosen all crumbling material then vacuum. Wet the areas to be fixed as it says on the tube. 3- Cut the tip small and pierce the inner seal - most caulk guns have a cutter plus a swiveling stick to pierce the inner seal. Then do the narrow cracks first. After caulking the cracks, smooth them with the 1” to press it in better and smooth your work. 4- Cut more off of the tip to make a bigger hole. Squeeze out an ample amount onto any deteriorating areas, press into voids and smooth with the 6”. Use the 1” to get excess off and scrape off what sticks to the 6” so you can use/reapply it. 5- Easy cleanup by scraping tools against each other to remove excess, get more off with a paper towel and then rubbing with water.
