Travertine counterops are amongst the most popular in many home kitchens and bathrooms. The countertops are produced from travertine, a type of marble stone with a pitted surface which gives it a high porosity. It must be sealed to make it more waterproof. It is one of the more affordable natural stones for construction purposes. Travertine is available in various attractive earth tones that range from gray to coral red as well as beige to tan. Although the stone is resilient and durable it isn’t as hardy as granite. With time, cracks may develop on your travertine. Fortunately, these can be easily repaired which restores the natural beauty of your countertop.
Step 1 – Brush out Dirt
Use a small scrub brush to clear dust and fine debris from the crack. The brush also helps to dislodge loose travertine along the crack edges. It is best to clear away as much of the loose travertine as you can. This ensures that you have a solid surface when you apply the repair material. It facilitates an effective bond.
Step 2 – Blow the Crack
Some fine debris is likely to remain within the crack after you brush. This will mingle with the repair material and reduce efficacy. Use a hair dryer to clear out the fine debris.
Step 3 – Clean with Acetone
Dab some acetone onto a sponge. Clean the area within the crack and reach within as far as you can. Be sure to clean the surface edges of the crack as well. Allow an overnight wait for the area to dry well.
Step 4 – Prepare the Epoxy
Follow the instructions that come with the epoxy to mix enough to fill the crack. You may have to mix a couple of different color pigments to obtain the desired match. It is best to mix the colors on a piece of white cardboard as this will give you a more accurate hue.
Step 5 – Fill the Crack
Use a palette knife to fill in the crack with epoxy. Press the epoxy firmly into the crack and ensure that it reaches right to the bottom. However, if the crack is very small, you may want to apply the epoxy with a toothpick for a neater job. Apply a bit more epoxy on the crack surface so that it slightly exceeds the countertop surface. Wipe away excess epoxy with a wet sponge. Allow 24 hours for the crack to dry completely.
Step 6 – Sanding
This helps to establish an even surface. Use a 400-grit sandpaper to smooth the filled crack surface. Sand steadily until the filled crack is flush with the countertop surface.
Step 7 – Sealing
Apply a travertine sealer to the repaired area with a foam brush. This acts as a protective layer and helps to waterproof the travertine. It also helps to create a uniform surface appearance. Apply a second coat of sealer after the first coat has completely dried.
