Features: SAFE AND EFFECTIVE: Our grout sealers are safe and ideal for repairing gaps, cracks, and grout lines. Strong Grout Paint: Designed to color old grout and fill holes and cracks, restoring tile floors, walls, bathrooms, showers, and kitchens. EASY TO USE: First, ensure the area around the gaps is completely dry. Apply the sticker along both sides of the gaps and press flat. Next, unscrew the cover and cut the tip to match the grout width. Then, squeeze the grout paint evenly along the gaps. Use a scraper or small stick to smooth the caulk into the gaps. Finally, remove the stickers and allow 24 hours for drying. WIDE APPLICATION: Can be applied smoothly to cement, tile, rock, glass, ceramic, plastic, and most other surfaces. Indoor and Outdoor Use: Suitable for both indoor and outdoor projects. The adhesive is cold resistant and remains secure in varying temperatures. Note: 1. Actual color may vary slightly due to lighting effects. 2. Allow 1–3 cm deviation due to manual measurement.
