Many people do not know how to apply a grout sealer. Let me take you through step by step guide on how to apply a grout sealer.

 Step 1- Choose The Right Grout Sealer

Before you begin your sealing task, it is important to find out the type of sealer that you want to use. Majorly, there are two types of grout sealers which include membrane forming and penetrating. A membrane-forming sealer works well on unglazed tile because it doesn’t bond to the glaze. This is a perfect sealer for floor tiles because it is designed with a nonporous membrane that enables the moisture to seep into the grout hence making it tough to dry.

The penetrating sealer is the most commonly used. It has silicone or latex composition that fills the grout pores, and when it is dry, it reduces the absorption of moisture stains.

Step 2- Preparation

Before you start, it is important to ensure that the grout you are using is completely dry and doesn’t have any debris. You need to have grout lines that are clean and free from cracks. When you are sealing, you should have a clean wet rag that you can use to remove any excess sealant. If you do not remove the excess sealant, it can end up sticking even on glazed tiles hence very difficult to remove.

If you do not have glazed tile, you should be very cautious when you are using any sealant. This is because the sealant will be directly absorbed into the tile hence changing its original color.

Step 3- Application

You should apply the sealer to the joints and the lines of the grout. You can apply with a sponge or brush, but most people use the spray-on method. Whichever method you choose to use, it is important if you begin applying the sealer from one fixed point mostly at the end of the tile. The application process should be systematic bearing in mind the corners and the joints.

It is advisable to follow a right-left pattern so that you do not end up missing any joint or grout line. This gives you the best results when you are sealing. Before you move to the next, ensure that you use your wet rag to clean any excess sealant because it will dry and become difficult to remove.
