## How To Seal Concrete Floor Before Tiling



When it comes to tiling a concrete floor, proper preparation is key. Sealing your concrete floor before tiling helps ensure that your tile installation will last for years to come. Knowing the right steps and materials to use to seal concrete flooring before tiling will help ensure that your tiled surface looks great and remains durable.



### Understanding The Benefits Of Sealing A Concrete Floor Before Tiling



Sealing your concrete floor before tiling will provide a number of benefits for your installation. The sealer acts as a waterproof barrier, preventing water from seeping through the concrete and into the substrate. This helps protect against mold, mildew, and other moisture-related damage. Sealing the concrete also helps the adhesive used to stick the tiles to the substrate bond properly, providing a strong and long-lasting hold that won’t come loose over time.



### Preparing The Concrete Floor for Sealing



Before you can seal your concrete floor, you need to make sure it is properly prepared. Begin by cleaning the surface of the concrete thoroughly, using a powerful degreaser like TSP or trisodium phosphate. This will help remove any dirt, grease, or other contaminants from the surface of the floor. After it has been cleaned, rinse it off with clean water and allow it to dry completely.



Once the floor is clean and dry, inspect it for any cracks or other damage. If you find any cracks in the concrete, use a concrete patching compound to repair them before proceeding with sealing. You should also use an 80-grit sandpaper to lightly scuff up the surface of the concrete floor. This will help ensure that the sealer adheres properly to the substrate.



### Choosing The Right Sealer For Your Concrete Floor



The next step is to select the right sealer for your particular application. There are several types of sealers available on the market, including both water-based and solvent-based options. Water-based sealers are more popular these days due to their low odor and ease of cleanup, but they may not provide as much protection as their solvent-based counterparts. On the other hand, solvent-based sealers are more durable and offer better protection against water damage, but they typically emit more fumes during application which can be hazardous if not properly ventilated.



### Applying The Sealer To The Concrete Floor



Once you have chosen the right sealer for your particular application, it’s time to apply it to your concrete floor. Start by applying a thin layer of sealer using a paint roller or brush. Allow this first coat to dry completely before applying additional coats as necessary. Make sure to follow all instructions included with the sealer for best results.



When both coats are dry, you can then move on to applying your tile adhesive and laying down your tiles on top of the sealed surface. Doing so will help ensure that your tiles are properly sealed in place and that they remain durable for many years to come.



### Caring For Your Sealed Concrete Floor



Once you have finished tiling your sealed concrete floor, there are a few things you can do to keep it looking its best. Regular sweeping and mopping will help keep dirt and debris off of your tile surface and prevent scratches or other damage from occurring. You should also avoid using cleaning products that contain harsh chemicals as these can breakdown the sealant over time and cause discoloration or fading of your tiles or grout lines.



By following these simple steps, you will be able to successfully seal your concrete floor before tiling and enjoy beautiful results that last for years to come!
