How To Seal Granite Countertops

Before you apply a sealer, make sure you test the granite’s absorbency.If your granite absorbs water or oil quickly, a penetrating sealer will make maintenance much easier.There is no such thing as a safe, stain-proof sealer for granite, but a good one will give you time to wipe up spills before they are absorbed.This is caused by polishing and it has nothing to do with how shiny your countertops are.

Step 1: The granite might need to be sealed.

Many countertops don’t need to be sealed, but applying a sealer is still common practice.If you want to test your surface, leave a few drops of water or a wet paper towel on the granite for 10 to 15 minutes.Continue to the next step if the water begins to soak into the countertop.The countertop should not be sealed if the water stays on the surface.If the granite is exposed to petroleum-based products, repeat the test with a few drops of mineral oil.If either test darkens the granite, seal it.Don’t seal it if the water does not soak in.The stone needs to be soaked into to make it effective, and if it can’t, it may leave a mess.

Step 2: Don’t put lemon juice on the counter.

According to the Natural Stone Institute, acidic products such as lemon juice can dull or etch your surface.Granite is vulnerable to acidic or alkaline-based products and can be damaged by products such as lemon juice and vinegar.

Step 3: Natural stone can be penetrating.

Only use products that are specifically designed for granite.A penetrating or “impregnating” sealer can be used to reduce absorption.This will protect your surface from stains for a long time.If you’re interested, you can read the fine print of the guidelines to make sure you get the right one.If you want the best results, choose a carbon resin sealer.There is a “fluorocarbon aliphatic resin” on the label.These are the most expensive and can provide years of good protection.”siloxane” or “silane” are worse at repelling oil than the next best options.Silicone and linseed-based sealers are not recommended.They are the least durable and will need to be resealed every eight months or so.Water or solvent-based sealant chemicals can be used.Both are adequate, but water-based is easier to apply and better for the environment.ioSeal Protectants are used to enhance and maintain the effects of impregnated seals without building up.

Step 4: There are instructions on the label.

It’s best to follow the instructions if you can.If the two sets of instructions contradict each other, use the method below, but always go with the label.

Step 5: The granite has to be cleaned.

After wiping the granite with water and dish soap or a specialized stone cleaner, wipe it with a dry towel or cloth.Do a final clean with denatured alcohol after using a degreasing product.Wait 24 hours to allow the granite to dry completely and return to its original color before continuing, or 8 hours if a strong breeze blows across it.If the construction projects are happening in the same room, it’s best to wait until after they’re done.Dust from construction can affect the protection.

Step 6: Gloves are required to protect the area.

If you’re going to apply a solvent-based sealer, open a window and put on a pair of gloves.The sealer won’t leave harmful chemicals in your kitchen.

Step 7: There is a small corner.

A microwave or other appliance is usually located in the corner of the granite.To make sure the sealer is compatible with the granite, follow the steps below.If the granite is discolored, look for a different product.The advice in the preparation section should prevent most of the problems, but the variety of granite makes it impossible to reduce the chance to zero.

Step 8: The sealer should be applied evenly.

If the seal isn’t in a spray bottle, use a clean, lint-free cloth or brush to cover the surface.The entire surface should not be wet.

Step 9: The stone should be absorbed by the sealer.

If you leave it on too long, it can cause discoloration.It takes about 20 minutes to soak into the stone, but trust the label for this one.

Step 10: If it’s necessary, apply a second coat.

When the first coat is almost dry, you can add a second coat if the label directs you to do so.To ensure even application, wipe this over the surface.

Step 11: Remove the seal.

After you leave the seal on for twenty minutes or so, wipe it up with a clean rag.A haze can be caused by too much sealer on the counter.

Step 12: The counter should be left alone for 48 hours.

This number is dependent on the exact product, but it will need to be cured for some time before it is effective.It’s a good idea to avoid washing the counter for the first 48 hours after application of some products.

Step 13: Re-sealing and future maintenance should be considered.

Sometimes re-sealing is unnecessary.Different types of stones need to be sealed.Simply by cleaning your surface with products containing ioSeal Protectants, you can remove the need to re-seal.The amount of time your surface needs to be sealed varies from condition to condition.Color, porosity, quality of the seal, and whether or not ioSeal has been used are the most relevant conditions.
