How to Seal Granite Countertops
Over time natural wear and tear can take a toll on any surface, even something as hard and durable as granite. If you notice that your granite counters aren’t shining the way that they used to, then this DIY guide is for you. You CAN make your granite shine like new! (And it is much easier than you think!) Here is how to seal granite countertops in just a few easy steps!
What you’ll need:
- granite surface cleaner spray
- Paper towels
- Liquid granite-sealer product
- Plastic tray
- Rubber gloves
- Sponge or sealer product applicator
- Clean white towel
- Trash bags
- Mineral spirits
Step 1: Prepping
You need to start off with a very thorough cleaning of your countertops. Remove any appliances such as toasters that are on the counters because you want to have access to all of the granite. Use your granite cleaner spray and a lint free, microfiber towel to remove any dirt, crumbs, dust or debris.
Lay out your supplies in advance! Put your liquid sealer, gloves, tray, and paper towels out so they are ready to use.
**Tip: the liquid sealer has a very strong smell. make sure to open windows and use fans to keep area well ventilated.**
Step 2: Pour Sealer
Put on rubber gloves, and then slowly pour just enough of the liquid granite sealer product into a plastic tray to cover the bottom of the tray by about 1/2 inch. You can always pour more product into the tray as needed throughout the process.
Dip the applicator or sponge into the granite sealer in the tray, and lightly press it against the side of the tray to get rid of the excess. Apply an even layer of the granite sealer product to the stone using a slow and steady back and forth motion. Run your applicator back over the surface to remove any bubbles or ridges in the sealer. If your kitchen is large with several sections of stone to seal, work in small sections as opposed to sealing the entire granite surface at once.
Make sure to follow all included manufacturer’s instructions!
**Tip:Be aware that granite sealer is often very thin and liquid-like as opposed to a gel texture, so drips are common. If spills or drips occur on other surfaces such as wood or tile, wipe them up immediately with a clean paper towel**
Step 4: Smooth Finish
After applying the sealer to the first area of granite, lean down and inspect the stone in a reflective area. Check to make sure that the sealer smoothly coated the surface without bumps or ridges. If any ridges occurred, simply reapply the sealer to that area and repeat until smooth.
Step 5: Repeat
Allow the sealer to cure for three to five minutes, and then wipe the counters down with a clean, white towel. Repeat steps 3 and 4 on all areas of the granite, working in small sections at a time. When finished, dispose of any used sponges, applicators or paper towels in a trash bag. If you choose to reuse your sponge or applicator, you may clean it with mineral spirits.
Step 6: Dry and Test
Once the entire granite surface has been sealed and wiped down, it will dry to the touch within three to five hours. Allow it to fully cure for 24 to 72 hours before placing appliances and accessories back on the counters.
You can check to make sure the granite sealer worked by sprinkling a bit of water on the counter. If it beads up without soaking into the granite, than you did the process correctly. In the end, your freshly sealed granite countertops will be impervious to liquid stains for at least six months to a year. Be prepared to repeat the process annually.
