Despite being one of the toughest natural stones a lot of people still find themselves asking, how do you repair granite? Exactly how depends very much on the damage that’s been done to it. There are some granite repairs that a DIY home enthusiast can carry out, but for others you’re probably better off calling in the experts.
Sometimes, if you haven’t already got the tools needed to carry out a granite repair it would be uneconomical to buy them, compared to getting in an expert. Other times, unless you’re experienced at working with granite, the time you’d require to learn the techniques for affecting the granite repair, simply mean it’s quicker and cheaper to get an expert in.
Honed granite surfaces will have been achieved by applying a preparation to the surface of the granite. If it starts to look worn or blotchy the whole thing needs removing and a new one applying. You’ll find a range of removers, treatments and sealers suitable for granite surfaces at your DIY store.
Repairing with Abrasives
A naturally occurring stone the highly polished finish on it that you saw when the granite was new was attained by abrading, grinding if you will, the surface. However, the abrading technique is one of constant refinement starting with coarse abrasive materials to ever finer ones, usually in conjunction with specially formulated liquids or pastes.
Granite is not only structurally strong but is it also chemically strong, that is to say that due to its mineral content and structure it isn’t susceptible to the ‘etching’ – that you can see on some stone counter tops due to attack by chemicals in everyday household cleaners. However, strong chemicals, especially acids, can cause etching on granite and, to restore the polished surface it needs to be refinished with a light abrasive polishing.
The same is true for any scratches that might appear on the granite surface. However, this time you’d probably need to start with a coarser abrasive, reducing the whole surface area to that of the bottom of the scratch and then using the finer abrasives to re-polish the whole surface. If your granite counter top is a particularly old one then over time it may well have simply dulled – again this top can be restored with a light abrasive polishing.
Cracks or Broken Edges
A crack or a broken edge on a granite worktop is simply bad news. In the case of a broken edge, depending on the location of it, you might be able to grind/abrade the broken edge smooth. Although you’ll lose the neat/clean edge that you had – it could look quite rustic and charming, almost giving it a natural hewn look.
Cracks needs filling with an adhesive mixed to look like the granite stone itself. This is best achieved by mixing the adhesive with some powder created from the granite itself. Test the mix on a part of the granite that isn’t visible for others to see, adjusting the mix to get the best possible texture and color.
Some factories producing granite tops inject a resin to alter its color. Over time, especially at the edges, this coloring can fade. The only real solution to this is to get a specialist in who can polish and enhance the edges – back to matching the granite counter top.
