Efflorescence Grout is the white mist on the tiles after installation. It usually does not come out with the initial cleaning of the tiles immediately after installation. Efflorescence of grout occurs when the salts in the grout leach through the tile surface. Although efflorescence can be removed from the tiles, you should wait at least 3 days after installation before applying the water, and at least 10 days before applying any acidic products containing. This will give the grout enough time to cure. It can effectively eliminate efflorescence grout by using the appropriate methods and products.
Instructions
1 use distilled white vinegar to remove slight opacity. Apply undiluted vinegar to the tile with a rag and clean the tile flowering. Follow this for cleaning the tiles with soap and water and dry well with a clean towel.
2 Mix ½ pound of sulfamic acid crystals in a bucket with 1 gallon of hot water for harder efflorescence of grout. Sulfamic acid is a product that is readily available at most home improvement centers.
3 Use A clean sponge to soak the affected area with running water. Let the tap water sit on the tile for about an hour.
4 Use dry towels to absorb the water from the tile. The acid solution is poured into the tile so that it forms puddles in the joints.
5 Scrub The tile with a nylon cloth. Let the acid solution sit on the surface for about 5 minutes, then rub the tiles again.
6 Clean the acid solution with wet rags in clean water. Dry the tile well with a clean towel.
7 apply a specific type of tile cleaner that is working with a product or remove misting grout. Follow manufacturer-specific instructions for application.
8 phosphoric acid sulfamic acid Substitute if the efflorescence is very bad. Phosphoric acid is a strong chemical that sulfamic acid and will be effective in eliminating the most problematic cases of grout efflorescence. Mix 1 part phosphoric acid in a bucket with 5 parts of running water. Apply and clean the solution in the same way used with sulfamic acid. Follow-up by cleaning the tiles with a tile cleaner suitable for the specific tile being worked.
Tips and warnings
- Wear rubber gloves, protective goggles and long sleeves and pants when working with acid-containing products. These chemicals can cause serious damage to your body.
- Never apply acid to tile without wetting first. The tile may suffer acid burns if it is not moistened prior to application.
- Test the product you are using in a small area of the tile before applying it everywhere. Look for any discoloration or damage to the product may cause the shingle.
