If you mix too much color with polyesters they will get gummy. I would suggest purchasing a black polyester. These are available from your stone chemical supplier. You may also want to try using an artists oil color called “Lamp Black”. This is... Read More

The marble tile was most likely improperly installed. Before you grind a floor you should sound the floor by tapping on each tile with a broom handle. If you hear a hollow thud sound then there is a strong chance that the tile has no setting material... Read More

These tiny holes are a common problem with not only travertine but can also occur on agglomerates. The best way to fill these is with what is known as a penetrating glue. This is water thin polyester that will flow into these holes. TIP Filling tiny... Read More

The knife grade has a thicker consistency, similar to peanut butter. Flowing is more liquid and flows easily. The knife grade is good for filling holes over 1/8 of an inch. For smaller holes the flowing grade will penetrate better. TIP Most... Read More

You are probably using a white or buff colored polyester. These colored polyesters are hard to color since they have a bright translucent hue. The best polyester to use would be a transparent type. To mix the proper color you can purchase artists oil... Read More

This is a problem in northern climates where de-icing salts are used. During the winter months deicing salts are used to melt the snow and ice. When the weather warms, the salts are dissolved and carried into the granite. When the granite dries, the... Read More

If these scratch patterns are what I think they are then they probably occurred during fabrication. Some polishing machines have ten inch diameter polishing heads. It is not unusual to have these patterns show up after the floor has been polished.... Read More

It sounds like moisture is trying to escape from the marble. This is a problem if a non breathable coating is placed on the marble. You will need to strip the coating off the floor and allow it to dry for several days. I would suggest polishing the... Read More
