Granite countertops are an amazing aesthetic to have in your home. Many homeowners choose to purchase homes with granite countertops (a great selling point!), and some even make the addition during home remodel projects because they prefer granite.
There are a few things that are different about having natural stone countertops over basic wood, tile, acrylic, or stainless steel countertops that homeowners must be aware of when caring for granite surfaces. Resealing granite surfaces as needed is necessary maintenance. This article details the steps professionals take prior to resealing and how to clean granite surfaces before sealing.
Why Do Granite Countertops Need to Be Resealed Regularly?
Even though granite is a low porous stone, the natural stone is still susceptible to liquids that may lead to discoloration or staining and even the growth of bacteria. The pores that are part of the composition of granite are what make resealing and refinishing a necessity for upkeep.
Resealing your granite countertops per the sealant manufacturer’s recommendations (usually specified on the label of the sealant that is purchased) protects your natural stone. Doing so will help keep these surfaces looking pristine, increase durability, and, most importantly, promote cleanliness. Sealing reduces the ability of harmful bacteria imbedding into your natural stone countertop. Most professional stone care workers can also refinish and polish your countertops to address blemishes like stains and scratches, a process that returns the stone to its previous luster.
How to Clean Granite Before Resealing
Before your granite countertops can be resealed, they must be properly cleaned. The first step is to take everything off your counter. Jars, appliances (microwaves, coffee pots, water boilers, your espresso, or Soda Mate), decorations, dishes and your dishrack, and whatever tchotchkes you might have taken up real estate, need to be cleared.
When cleaning the granite countertop, it is best to do so thoroughly. You must remove all the grease, crumbs, dirt, coffee grounds, and whatever else might have been sticking to the surface with a soft sponge or soft microfiber cloth. Warm water and non-acidic soap work best. You will want to avoid any abrasive cleaning products or materials to prevent unintended damage to your granite during the cleaning process. Things to avoid include ammonia, bleach, vinegar, and lemon cleaners as all can damage your countertop’s finish.
Your Granite Countertops Must Be Completely Dry Before Sealant Application
It is necessary to let your granite countertops dry before applying any sealant. This can take anywhere between 12 and 24 hours. You can go by the manufacturer’s specific recommendations or err on the side of caution and wait a full 24 hours before resealing your granite surfaces. You cannot use the countertop while it is drying; otherwise, you will be back to square one.
Why? Because liquids disrupt the sealant’s ability to do its job. If the granite is wet during application, the sealant may not bond as well to the surface, and the finish can have a hazy appearance. If you notice this, it means that your granite countertop has been improperly sealed. Weak seals do not offer as good of a defense from unwanted stains, moisture, and bacteria. It is best to let your granite countertops dry overnight after deep cleaning them before resealing.
Applying Sealant to Your Granite Countertops
Once everything is completely dry, it is time to apply the sealant. Applying a small amount of the sealant to a part of the countertop that is normally obscured and out of view for a test is a smart move. It is pertinent that you follow the manufacturer’s instructions. If you want to read more about the process, you can check out Angi’s List and Better Homes & Gardens.
