Caulk can be used to fill and seal grout lines between tiles.
Ceramic tiles are a common industrial ceiling covering material. Once properly installed, they protect the ceiling from moisture and stains the same way they protect walls and floors. Homeowners are beginning to choose this unconventional ceiling material. Adhesive is used to bind tiles to your ceiling to insure a solid bond. Grout is a heavy material that will droop and fall leaving waves and gaps. Silicone caulk will seal the grout lines in your ceiling tiles and form a barrier that will repel moisture and liquid for many years.
Instructions
1. Remove all furniture and other objects from the room. Cover the entire floor of the work area with dropcloths. Overlap the cloths to prevent accidentally contaminating the flooring with caulk.
2. Slide the tip of a tube of caulk into the cutter on your caulk gun. Line the 1/8 mark on the tip up with the edge of the cutter. Squeeze the trigger and snip off the end of the tube.
3. Open the puncture tool on the end of the frame of the gun. Push the puncture tool into the hole in the tip of the caulk tube to pop the thin diaphragm inside of the tube. Slide the tube into the rear of the frame of the gun and lower the tip of the tube into the notch at the front of the frame.
4. Use your caulk gun to fill the grout lines around each tile with silicone. Smooth each bead of caulk with a wet rag. Work in 3-by-3-foot sections. Avoid leaning too far as this will tip your ladder. Let the caulk cure for 24 hours before removing the dropcloths.
