Once it has set, sand it down to blend information technology in with the residuum of the stone. To repair a polished granite it is better to use a clear resin and add a black paint to it. When it has set, remove the backlog with a pocketknife blade every bit opposed to sanding downward.

HOW TO REPAIR TRAVERTINE
Here are three examples of how to repair travertine. A large chip repaired with a pocket-sized piece of travertine. A long crevice repaired with a resin filler, and a large hole besides repaired with a resin filler. Finally, some advice on filling small holes in travertine.
1. A DAMAGED TRAVERTINE STEP
This Travertine stride was damaged during a commitment to an part edifice in Fundamental London. A common problem. Travertine comes in many unlike colours and different shades inside each colour. You must first clean the stone as all-time as you can. One time clean you tin then match the colour of the travertine. When you have the all-time possible colour match of your travertine, yous can then attempt to match the veining.
The damaged role of the travertine is cut away, a small piece is cut to fit into the space. The piece should be cut to match the veining in the Travertine step.
Repairs like this can be repaired with the same resin adhesive used to fill the holes in travertine. The basic buff colour resin is a skillful friction match for this piece. If needed you can add together pigments to the resin for a closer colour friction match.
The excess resin is removed. Finally, to requite the repair a nice clean look the balance of the nosing is sanded back.
two. A CRACKED TRAVERTINE FLOOR TILE
To repair a crack in travertine, thoroughly clean the stone earlier you start the repair. The last thing you want to see is dirty lines on either side of your repair. Leaving information technology muddied volition always describe your eyes to a repair that should be invisible.
Well-nigh cracks in travertine happen along the vein which makes them easy to repair and hide. I apply a vitrify coloured resin filler and mix about 3 or four batches; each one is a slightly different shade.
Aside from the original buff colour of the resin. Ii further batches are mixed, i with a chocolate-brown pigment added the other with a white pigment. Depending on the colour of the rock sometimes a 4th is needed. To reach this vary the amount of paint in either of the batches you have mixed.
Applying the resin; Mix each batch separately with the hardener and apply each one intermittently along the crack. This will break up the colours and look more natural. Depending on the terminate of your travertine, if polished scrape off the excess filler with a knife bract. If the rock has a honed stop remove the excess with a 120-dust abrasive. For a finer stop go on sanding with a 220 or 320 grit abrasive. The best abrasive disks for Natural rock is Silicone Carbide.
3. A LARGE HOLE IN A TRAVERTINE FLOOR TILE
This cross cut travertine floor tile was damaged by a carpeting fitter. I needed iii different shades of filler to match the colours and pattern of the travertine flooring tile. When matching these colours I used a pigment called Ocra, this gives the resin a yellow/brown tint.
I mixed them with the hardener separately. Each colour was added intermittently in various shapes to form a pattern. Once the filler had set, I sanded them down which helped to blend them in further. Finally, I polished the travertine to lucifer the residuum of the floor area.
SOME Communication ON FILLING HOLES IN TRAVERTINE
The process is the same for filling pocket-size private holes in travertine merely only one shade will do. The larger the hole the more shades are required to give information technology a more natural expect. If yous have a lot of small holes spread across a large floor expanse one shade will practice. To avoid waste, mix your filler and hardener in very small batches.
To remove the excess filler, I discover it is all-time to use a scrapper with a new knife blade fitted. Endeavour to avoid sanding down the private repairs it will leave low-cal patches on the floor. The whole floor volition have to be cleaned subsequently if you practice so. Remember e'er clean the damaged area beginning and piece of work in small areas until complete. Spread the project over ii or iii days to make it easier for yourself. Finally, make clean your tools regularly throughout the project to reach better results.

The surface of the other parts of the marble vanity superlative was badly scratched but these were non deep scratches. The use of the wrong cleaning products left the appearance of the marble looking very dull and flat.
REPAIRING THE DAMAGED Expanse AROUND THE TAPS
The area around the taps could not be sanded back equally information technology would leave a dip in the stone. When the new taps are fitted h2o would collect around the taps and limescale would course once more.
The expanse effectually the taps is cleaned. Subsequently, the damage is repaired with a resin to lucifer the colour of the marble. Once the resin had set and hardened the marble was then restored using diamond polishing pads.

Some wedges were inserted into the joints and nether the window sill to help concur the granite in identify. There was one large chip to repair in the middle, as well some pieces of granite had flaked away. To match the granite colour I used a transparent resin and added a black pigment to it.
The backlog resin could not be sanded off as this would touch the original polished finish of the granite. I removed the excess with a knife blade. Finally, the surface was polished with Lithofin MN Polish.

GRANITE BAR Elevation
This damaged granite bar top in a London casino had to exist repaired with just resin. The original could not be constitute. A challenge with repairing granite with only resin is not just matching the colours and pattern in the stone. Assuasive for changing light conditions is besides necessary. The two different materials, granite and resin never look the same as the low-cal changes.
The bulk of the repair is a blackness resin filler. Once practical information technology is roughly shaped to match the profile of the bar top. This kickoff layer of resin is 3mm to 4mm short of the surface.
The second and third layers of resin will have the various colours added to match the color of the granite. I used 2 resins with pigments added to match the colour and patterns in the granite. I made about three batches of white resin with different shades of dark-brown paint. These were layered over the black resin. When set the backlog was removed so that it was affluent with the residuum of the granite. The white resin with the pigments does not shine as much equally the granite when polished.
A transparent resin with a very small amount of brown pigment was used to lucifer the vein-like patterns. The transparent resin was added between the white resin and over the tops of some of them. The transparent resin shines more than the white resin.
The resin repair is then shaped and polished to match the profile of the granite bar. The two different resins, with different shades of brown, volition then react differently equally the lights alter.
ONYX TABLE REPAIR
This is how I repair a part of an Onyx table with a slice of marble and a resin adhesive.
The trim effectually the bottom edge of this Onyx table had broken off and part of it is missing. Onyx is very expensive to buy and there are not many suppliers in London. Matching the missing piece is exist very difficult. I decided to repair the impairment with a small-scale piece of Arabescato Marble. Together with the marble, I use a articulate resin to repair the Onyx.
The Arabescato Marble is cutting from a 10mm thick flooring tile. Information technology is milled downwards to virtually 6mm thick and shaped it to lucifer the missing piece of Onyx. The ii pieces of the Onyx trim that had been saved were stock-still in identify using the resin adhesive. The piece of marble is and so fixed in place next to them merely set dorsum about 4mm from the surface.
I mix vi batches of clear resin with different levels of green pigment. Another four batches of the resin with different levels of brown pigments to make a vein. When complete the vein will form a seam between the repair and the original Onyx.
The resin is built upwardly over the marble to lucifer the surrounding Onyx. Additionally, I added my brown resins to match the veining on other parts of the table.
Resin repair completed, the new piece is sanded down and polished to match the rest of the onyx.
CARRERA MARBLE Bathroom
This lilliputian project was not and so much a repair. However, I was needed to dismantle the marble around the toilet and bathroom, without damaging the marble. The pump for the macerator in the toilet was faulty and the plumbers needed to gain access to information technology.
The plumbers were non too sure where the pump was located after the marble effectually the cistern was removed information technology was suggested that the pump may be located backside the bath panel. The marble around the top of the bath and the bathroom panel was carefully removed to reveal the pump for the macerator. The plumbers were then able to easily replace the pump.
To avoid the same trouble in the time to come we decided to make an access console for the pump to make futurity serving easier.
I cut a department from the side panel and fitted information technology to allow easy admission to the pump. A bead of silicone both sides of the console is used to hold it in place. The silicone would just need to be cut become gain admission to the pump in the futurity. A gap at the top of the panel is left to help with the removal and refitting when necessary.
The modified console together with the piece of marble around the acme of the bath is fixed in place. The marble around the top and side of the cistern were fixed back in identify. Now the bathroom is back in apply without the toll of replacing whatever of the marble.

HOW TO REPAIR A Scrap ON A GRANITE COUNTERTOP
I of the most mutual natural stone repairs I carryout are chipped edges of granite countertops. Though these repairs are common it is nix to do with the quality of the granite.
JUST BAD LUCK
In most cases, it is simply bad luck when the granite worktop is hit on the edge with an object. Something as fragile equally a teacup tin flake granite if caught at a certain angle.
THIS IS HOW I REPAIR A CHIPPED COUNTERTOP WITH AN EPOXY RESIN
The damaged granite is Bluish Pearl, information technology was chip while loading or unloading the dishwasher below it.
CLEAN THE DAMAGED AREA
First I make clean the damaged expanse. If the fleck has been there for a few weeks or months there will be some ingrained clay in it.
The best way to make clean out the damaged area is to use a small corporeality of the resin. Mix the resin with the hardener and spread a sparse layer over the damage and exit it to set. Merely as it sets utilise the border of a pocketknife blade to remove the resin.
Nigh of the dirt and any loose material volition come away with the resin. A final clean with a little white spirit and the chip is set for repair.
TRANSPARENT EPOXY RESIN
To repair this slice of Blue Pearl Granite I volition apply a transparent resin. Once prepare and the excess removed the transparent resin is easier to shine. The transparent resin takes a fiddling longer to set, so I will have fourth dimension to adjust the pattern as it sets.
4 Dissimilar COLOURS
The next thing to do is mix the resin with dissimilar colour pigments to match the colours in the granite. 4 different colours are mixed to match the diverse colours in the granite. I basically started with a dark blue mix and mixed lighter versions of information technology. Because of the mottled effect of the patterns in the granite, the colours practice non have to be verbal.
APPLYING THE RESIN
One at a time I add together the hardener to the resin, then utilize the lightest then the darkest resin mix. As they are setting, I use a bradawl tool to poke little holes in the resin. I besides use the edge of a knife blade to change the pattern.
Calculation THE COLOURS
Once the start two colours are set, I remove the backlog with a new knife blade. The areas where I poked piffling holes in the resin as it was setting, I add the other 2 colours. The other two colours are added intermittently to break up the colours.
REMOVE EXCESS AND Smoothen
Finally, in one case all the resin has set the excess is shaved off with the knife bract. To go far easier to remove the excess I lubricated the bract with a little white spirit. The repair is then sanded with some ultra-fine silicon carbide abrasives, which does not scratch the granite. To complete the repair the granite countertop is polished with a good quality natural stone polish.
