The correct way to install vinyl tiles would be to butt them together as closely as possible. But defective tile or installation shrinkage can create modest gaps that allow water and dirt to accumulate. This mars the look of the ground, and sometimes, can harm the subfloor. If you do not want to pull up and re-lay the shingles, filling the gaps with 100 percent silicone caulk is the next greatest thing.
Floor Preparation
Silicone caulk requires a clean and completely dry surface for maximum adherence. An old toothbrush and a vacuum work nicely for brushing and removing loosened debris. Because silicone mistakes are a nightmare to eliminate after, protect the borders of the tile by carefully taping them away with painter’s tape.
Filling the Gaps
Silicone is cluttered, so it helps to use a few tricks when working with it. Employ a very small bead in the tile gap and smooth it securely using a damp rubber-gloved finger. If you use the ideal amount, there ought to be very little excess. Peel off the painter’s tape immediately after filling the gap. If any caulk inadvertently gets on the shingles, wipe if off fast with rag dipped in rubbing alcohol. Examine the tube for precise drying occasions, but most silicone caulk is fully set in 24 to 48 hours. Choose a crystal clear or impartial caulk color matched to the neutrals in the tile for best results.
