We are renovating our Bathroom. Was wondering how many coats of tile and grout sealer will be needed
Hello @Fren
Welcome to the Bunnings Workshop community. It's wonderful to have you join us, and thanks for sharing your question about the grout sealer.
For most tile and grout sealing projects, applying one to two coats of Davco Sanitized Tile & Grout Sealer will provide effective protection. The number of coats required will depend on how porous the grout and tile are.
Before you begin, make sure the surface is completely clean, dry, and free from any dirt, dust, grease, or other contaminants. Once the area is prepared, apply an even coat of sealer using a narrow brush, allowing it to penetrate the grout lines. Take care not to over-apply the product, and wipe away any excess sealer that comes into contact with the tile surface straight away using a damp cloth to prevent residue or smearing.
After application, allow the sealer to dry completely for approximately 24 hours. Once dry, you can check whether the grout has been adequately sealed by placing a small amount of water onto the grout lines. If the water beads on the surface the grout is properly sealed and no further application is required. If the water is absorbed into the grout, apply a second coat of sealer and allow it to dry before testing again.
Following this simple process will help ensure the grout is properly sealed and protected, providing long-lasting performance and helping to keep tiled areas looking their best.
If you have any other questions we can help with, please let us know.

Thank you for your response Eric. Could you please suggest which brush do i buy from Bunnings? Also just to clarify, the sealant just needs to go on the grout?
Hi @Fren,
For applying the sealer, a small craft paint brush (around 12–25mm wide), such as the https://www.bunnings.com.au/boyle-size-14-craft-taklon-flat-brush_p0440448 , works well. It allows you to apply the sealer accurately along the grout lines without using too much product.
Yes, in most cases, the sealer only needs to be applied to the grout lines. While it's perfectly fine if a little gets onto the tile surface during application, it's best to wipe any excess off the tiles with a damp cloth before it dries to avoid any residue.
If your tiles are natural stone or another porous tile, they may also require sealing. However, if they're glazed ceramic or porcelain tiles, only the grout needs to be sealed, as the tile surface itself is already non-porous. Please let me know if you have further questions.
