Indoor Drywall Cracks
1. Use a box cutter or thin, sharp blade to carefully remove any drywall residue present in the crack. This will allow for an extra-smooth application of your mending agent.
2. Pipe the mending agent over the crack with a fitted nozzle, and use a scraper to spread the agent across your wall and remove the excess.
3. Let the agent dry for 4 hours. Sand and paint if necessary. You're done!
Bathroom Tile Cracks
1. Thoroughly clean out the crack with a bathroom cleaner or detergent to ensure no grime or residue is left behind. Since bathroom walls are exposed to more moisture than other rooms of the house, be sure to let the crack dry out before you begin your repair.
2. Pipe a mold-proof mending agent over the crack with a fitted nozzle, and use a scraper to carefully spread the compound and remove any excess. Use a damp sponge on the tile around your repair site to keep your mending agent centralized to the crack.
3. Let dry for 4 hours. Carefully sand down if necessary. You're done!
Exterior Wall Cracks
1. Scrub the wall crack clean to ensure no outdoor debris has made its way into the opening in the brick, stucco, or concrete.
2. Pipe a weather-resistant mending agent into the crack, and use your scraper to spread it smoothly and remove the excess.
3. Let dry for 4 hours. Sand and paint if necessary. You're done!
