Repairing Chips in a Granite Countertop

By Edited Jun 14, 2015 0 0

Granite countertops add value and visual appeal to a home. Granite offers a strong, durable and luxurious surface in both kitchens and bathroom. Granite is heat resistant, strong and durable, but it is not impervious to damage. Because granite is a naturally occurring stone it is rarely perfect. Suppliers custom cut countertops to fit perfectly into a kitchen or bathroom. After much research, shopping and comparing, most homeowners are very happy with their choice.

Upon closer examination many people notice tiny chips or perhaps a decent sized chip on the countertop, leaving many to wonder how did they chip their prized granite. Wracking their brains to try to remember if they dropped something heavy on the granite or if the kids may have done something to damage the surface, so many thoughts to try to figure out what could have happened. Rest easy, you didn’t do anything and neither did your kids. The chip usually isn’t a chip at all, it’s a pit. Being that granite is a natural stone, the surface has small holes, imperfections and flaws. During the polishing process, it is filled in. Over time and through use the filler, which is typically, a thin film used to help create the shine on the surface of the granite, separates from the flaw and becomes apparent.

Trapped bits of dust and food or soap residue highlight the missing chips and make the pits stand out. The small imperfections detract from the beauty of the countertop and leave many homeowners unhappy with their investment. Chips and pits can be repaired and restore the granite countertop to its beautiful and appealing surface, free of flaws, chips and pits. Repairing the granite surface is not overly difficult making it a perfect project for a do it yourself type homeowner.

There are two repair methods for filling in chips on a granite surface, depending on the depth of it and the color of the countertop. The diameter of it is not as much of a concern as the depth, along with the color. If the color at the base of it reveals a color other than the one that surrounds the flawed area, use a color resin to repair the surface. If the chip or pit is small or the color at the base of it is the same as the color that surround it, use a clear epoxy filler.

Clear Epoxy Filler

Insert the straw into the nozzle of a can of compressed air.

Point the straw at a chip and press down on the top of the can to blow the air and force loose bits of food, dirt and dust out of the depression.

Scrape the inside of it with a wood toothpick to remove soap residue and bits of food from the area.

Dampen a rag with plain water and wipe the flaw and the area around it. Dry the countertop with a soft cloth.

 Lay pieces of low tack blue painter’s masking tape around it getting it as close as possible to the edge of the flaw as possible without covering any part of it.

Submerge the end of a cotton swab into denatured alcohol. Rub the cotton swab over it and exposed area of granite around it to remove oil, grease and cleaner residue from the defect.

Insert the tip of an adhesive syringe into the top of a tube of clear epoxy filler gel. Pull the plunger on the syringe up to draw the epoxy into the syringe.

Insert the tip of the adhesive syringe into it or if the chip is too small to accommodate the tip of the syringe place it over the top of the chip.

Slowly and gently press down the syringe’s plunger to express a drop of the clear gel into the chip. If the epoxy does not fill the chip entirely, squeeze out another drop. Squeeze the epoxy filler out of the syringe, drop by drop until the chip is filled even with the immediate surface area.

Place a flexible plastic putty knife at a low angle to the countertop and drag it across the repair to remove any excess filler.

 Dip a cotton swab into the denatured alcohol and wipe the surface around the repaired chip to remove excess clear epoxy filler from the granite surface.

Peel the painter’s tape off the granite.

Allow the clear epoxy filler to set and harden for two to three hours.

Color Resin Filler

Blow dust, dirt and other debris out of the chip with a can of compressed air.

Scrape the chip with a wood toothpick to remove stuck on food particles and dirt.

Wet a rag and wipe the area clean. Dry the countertop immediately with a soft cloth.

Dip a cotton swab into denatured alcohol and clean the inside edges and base of the chip. Wipe the granite surface surrounding the chip with the cotton swab.

Put pieces of low tack blue painter’s masking tape around the chip getting as close as possible to the defect without covering any part of it.

 Hardware stores and home improvement stores sell two part, colored, epoxy resin kits. Match a kit as closely as possible to the color of the countertop.

Pour equal amounts of the colored resin and the hardener onto an old plastic lid or a disposable plastic bowl or plate.

Mix the two ingredients together with a flat toothpick or the small flat plastic knife that comes with the kits.

Scoop up the colored resin onto the flat plastic knife or wood toothpick and carefully push the resin into the base of the chip.

 Continue to add resin to the chip and press it down until the chip is filled with the repair filler.

Wet the corner of a lint free cotton rag with denatured alcohol.

Gently rub the wet corner across the surface of the resin to level the repair and make it smooth.

Peel off the painter’s masking tape.

Allow the color resin to set and harden for three to four hours before using the granite countertop.

 Tips

Clear epoxy filler is hard to notice after a repair because epoxy allows the color of the granite to show.

Many times it is hard to match the color a resin filler with the granite color.

Clean drips and spills of filler off the granite countertop immediately.
