The granite countertops are one of the most durable options available for kitchens, bathrooms, or any other space. But they have a porous surface that needs to be sealed. It is an interesting and fun process. However, even the slightest mistakes can disrupt the sealant quality. Besides that, you must have knowledge about how frequently a countertop must be sealed. It helps you to prevent sealing the granite countertop too quickly or too late.
In this guide, we will study a step-by-step guide to sealing granite countertops and all the questions related to it:
Tools and Materials You'll Need
Before you start countertop sealing, it is necessary to gather the following items:
- The granite sealer (choose the one that penetrates and is specifically designed for use with natural stones)
- Soft sponges or pads for applicators
- Cleaning with pH neutrality or granite cleaners
- Paper towels
- Protective gloves
- Spray bottle (if not sealed)
Optional:
Masking tape to protect walls or sinks
Plastic sheet to cover surfaces
Choose the Right Granite Sealer
There are many granite sealers on the market. The choice of the right one is essential for efficient stone sealing.
- Topically Sealing Agents (Good for areas that have very little traffic)
- Permeable Sealers (Perfect for kitchens and bathrooms)
- Enhancing Sealers (Ideal for those wanting the “wet look” finish)
5 Steps for Sealing Granite Countertops
If you are sealing your countertops or refreshing old ones, this method can be used for all granite surfaces. Follow this five-step guide to create a non-porous, smooth granite countertop.
Step 1: Clean the Countertop
Before applying the sealant, it is essential to ensure that the surface is clean and free of dust. It’s an essential process, and one has to be attentive to it.
Every dirt particle that is left could interfere with the sealant, making the appearance not as clean. Here’s a way to remove the dirt from your countertop:
- Take everything off the counter.
- Utilizing a cloth or soft-bristle brush, remove all dust and particles that are not needed from the surface.
- Keep the cleaner in place, mix it with water, and make a dilute solution.
- Spray it onto the surface, allow it to sit for a while, then scrub off the stain with a soft cloth.
- Also, rinse with water to ensure that no cleaning products are left in the water.
- Let the surface dry for a minimum of 30 minutes.
Step 2: Apply the Granite Sealer
After cleaning, take a few minutes to allow the countertop to dry before applying the sealant. Here’s the correct method of applying the sealant:
- Shake the sealer bottle thoroughly.
- Pour the sealer over the granite’s surface.
- Make use of a soft cloth sponge for spreading it equally with circular movements.
- Make sure that the surface is covered completely, especially around sinks and other areas frequently utilized.
- Let the sealer sit for over 15 to 20 hours or follow the instructions on the product packaging.
- If the sealer is absorbed too quickly, apply more of it to ensure that it’s completely saturated.
Step 3: Wipe Off Excess Sealer
Once you’ve applied the sealant, you must wait some time and be sure that the sealant is not completely dry yet. This is crucial and involves the removal of any excess sealant. In some cases, the sealer in certain areas is greater than in other areas. It is important to avoid this by following these steps:
- Dry, clean microfiber cloth, removing any sealer.
- If there is an extended delay, this could lead to the formation of a cloudy or sticky residue.
- Make sure the smooth surface is shiny.
- Make sure to work with small portions. This will ensure even coverage and help avoid drying lines.
Step 4: Apply a Second Coat (If Needed)
Based on the degree of porosity in your granite and the sealer you apply in the application, the method of applying the second coat may differ. Certain granites that have higher density will only require one coat, whereas lighter colored or porous stones need two coats. If, for instance, your countertop is porous and has a significant number of pores, then you absolutely must apply a second layer. Here’s how you can put on the sealant layer:
- Wait for a few minutes before applying another.
- Repeat the process exactly as you did before.
- Allow the second coat to absorb and dry thoroughly.
Step 5: Allow Proper Curing Time
After the sealer has been put on, the stone needs some time to set so that the sealer will be able to adhere. It is important not to use the countertop for at least 1-2 days following the sealing. Avoid placing any heavy objects like cooking equipment or food items within the space for a minimum of 24 hours. The entire curing process could take up to 72 hours, based on the kind of item.
Once it is cured and dried, the granite is left with a shiny, fresh-looking look. It is also secured from spills and stains. Also, the sealant and polishing will provide a fresh look to your counters. However, you have to be in the moment and wait for each step to be completed until the time you need.
Common Mistakes to Avoid When Sealing Granite
Any small mistake could cause a change in the effectiveness of the sealing process. These are the mistakes to keep in mind:
- Sealing countertops that have become dirty. Always clean the countertop thoroughly before sealing.
- The drying time isn’t getting effective absorption. The presence of moisture can hinder the absorption process.
- If you apply excessive amounts of sealer, it could cause the appearance of streaks or cloudiness.
- By using acidic cleaners, they deteriorate the sealer and also the granite.
- If you don’t take care of regular maintenance, even the most efficient sealer can wear away with time.
How to Maintain Sealed Granite Countertops?
Once you’ve sealed the granite countertop, maintenance is easy. You can easily clean the surface using just a piece of cloth. But, you need to take care of a few things, which are:
- Use pure and gentle products
- Wipes Spills immediately
- Use mats and coasters for hot items
- Conduct a water test every year
If you implement these tips by following these guidelines will prolong the lifespan of your seal and keep your countertop in top condition for an extended period of time.
Final Words:
The process of sealing a granite countertop is simple, but you need to be careful about some things. From cleaning the countertop to removing the excess sealant, every step needs careful consideration. Other than that, you must avoid mistakes like not applying the sealant during its required time or applying too much sealant.
