Repair Granite

What is Granite?
Granite is an intrusive igneous rock (formed from the slow cooling of magma underground), the major component of the continental crust, coarse grained, and composed of quartz along with a variety of feldspar minerals and micas.

How to repair granite chips:
You can repair granite chips almost seamlessly with Mister Glue. The nature of this glue makes it so the tighter the fit of the two pieces the better the bond. Mister Glue is an industrial cyanoacrylate which is the same base as superglue or Krazy Glue. It has been distilled numerous times so that the solvents have been removed resulting in a product that is many times stronger than supe glue.

If a corner has broken off a granite countertop clean both surfaces of dust and dirt. Try not to scrape or sand as this will change the shape making for an imperfect fit. Mister Glue will not fill gaps and as said earlier the closer the fit the better. It is a good idea to practice a little putting the pieces together because you do not have much time to move them around once they touch.

Once you know that the fit is exact, place a small bit of glue on one surface of the broken granite. Make sure that is enough that it will cover the whole surface - spreading when the two pieces are pressed together. Hold the two sections of granite tightly together for a few seconds - a bit longer if the section is larger. Some of the glue may squeeze out of the joint - leave that to dry up a bit then take an Exacto Knife and gently scrape off the excess. If you wipe it the glue will spread and possibly stain the stone.

Full cure time is several hours but it takes only seconds for a tight, secure bond to occur. Most of the time you will not be able to remove the piece within a few seconds.

If the granite is very porous you can use a bit more glue or an accelerator. Sometimes water will work as an accelerator - it primes the surface so that the glue will not soak in. If you use water to prime the surface, let it 'dry' before applying the glue. You definitely do not want a wet surface.

For a small granite chip on the edge of the seam that is still left after you have glued the two pieces, you can take a bit of dust from the granite - grind it and place it in the crack and put a few drops of glue over it. Let it set then you can scrape or sand it smooth. It will be the same color but the finish will obviously be different.
