Grout discoloration can occur when you add too much water to powdered grout throughout the first tile installation. Improper cleaning of grout haze in the surface of the floor or wall, or even failing to let the grout cure for the amount of time indicated by the manufacturer, can also result in uneven grout colour. Removing the original sealant and resealing using a color-enhancing grout and tile sealer can help darken the esophagus by one colour. Applying a knitted grout tint can help correct or change uneven grout colour. A lacquer thinner can lighten grout and help disguise uneven color.
Darkening Grout using Color-Enhancing Sealer
Vacuum a tile flooring to remove any loose dirt. Clean floor and wall tile having an all-purpose cleaner and allow the surface to dry.
Mix a tile and grout stripper with water based on the manufacturer’s direction. Liberally apply the stripper to the wall using a sponge to the floor with a mop.
Allow the stripper rack for at least three minutes. Do not enable the stripper to dry on the floor or wall. Scrub the wall or floor with a nylon scrub brush to remove the old sealer.
Wash the surface with clean water. Allow the surface to dry.
Protect baseboards and adjoining flooring using plastic sheeting. Secure the sheeting with painter’s tape to keep it from going.
Apply a color-enhancing tile and grout sealer to the wall or floor with white terrycloth towels. Allow the sealer sit undisturbed for at least three minutes. Use a clean towel to wipe any excess sealer from the surface.
Wait 1 hour and apply another coat of colour enhancing sealer. Allow the newest sealer to cure for at least 12 hours before walking on the floor or permitting water to come into contact with the surface.
Acid Etching and Colour Tinting
Dilute acid etcher with water based on the manufacturer’s instructions. Make sure that the acid etcher is designed for use with grout and your tile stuff. Do not use muriatic acid to etch the esophagus.
Pour the diluted etcher into a grout sealer applicator bottle equipped with a little roller tip. Put on the etcher to the grout lines. Allow the etcher sit around the grout to get at least one minute, but no more than implied by the manufacturer.
Scrub the grout line using a soft wire brush. Wash the surface with clean water and let it dry.
Shake a container of water-based grout tint to blend it. Move the tint into a squeeze bottle with a narrow tip opening up.
Apply a thick bead of tint across the grout line. Use an old toothbrush to spread the tint evenly over the combined using a back-and-fourth motion. Wait 1 hour to apply another coat of tint if needed.
Fill a plastic spray bottle with clean water. Mist the grout line after waiting at least one hour after the final tint application. Wait five minutes before cleaning any tint residue from the surface of the tile using water plus a fine-nylon scrub pad. Allow the tint to treat at least 24 hours.
Pour grout sealer into an applicator bottle equipped with a brush tip. Use the sealer straight to the grout line.
Wait at least five minutes before wiping off any excess grout sealer using a clean towel. Apply additional coats of sealer until the grout no longer absorbs the sealer.
Allow the grout to cure for one hour. Wipe any sealer residue from the surface of the tile using a sponge and clean water. Allow the sealer to cure for at least 12 hours prior to coming into contact with the surface.
Stripper and Lacquer Thinner
Pour a gel-based stripper into a squeeze bottle with a narrow tip opening up. Use the stripper to the grout lines.
Wait at least two minutes to get blisters to appear along the grout line. Wipe the stripper in the grout lines with wet rags.
Implement lacquer thinner liberally using a little paintbrush to the grout lines. The thinner can help lighten the colour and remove any extra stains. Use absorbent rags to blot the excess thinner. Allow the surface to dry for at least 24 hours
Spread the rags on a level surface outside to dry thoroughly. Do not abandon them wadded up or in a pile as the rags could spontaneously combust. Place the dry rags in sealable food storage bags and dispose of them.
Protect baseboards and adjoining flooring using plastic sheeting. Secure the sheeting with painter’s tape to keep it from going.
Apply a color-enhancing tile and grout sealer to the wall or floor with white terrycloth towels. Allow the sealer sit undisturbed for at least three minutes. Use a clean towel to wipe any excess sealer from the surface.
Wait 1 hour and apply another coat of color-enhancing sealer. Allow the newest sealer to cure for at least 12 hours before walking on the floor or permitting water to come into contact with the surface.
