1. Product introduction:
This product is a cement-based caulking material made of high-quality quartz sand, cement, redispersible rubber powder imported from Germany and inorganic pigments. It has good adhesion, flexibility, waterproofness, impermeability, crack resistance, freeze-thaw resistance, and resistance to rapid changes in cold and heat. It can improve the aging resistance and long-term durability of the facing and overcome the problems caused by caulking with ordinary cement mortar. , prone to defects such as cracking, water seepage, and shedding, and is a green and environmentally friendly product.
2. Scope of application:
This product can be used for caulking of interior and exterior wall tiles, floor tiles, marble, swimming pool wall tiles, granite and other facing materials. It is available in a variety of colors. for selection. The product has good elasticity and excellent water retention performance, which can avoid cracking of the caulking agent due to shrinkage of ceramic tiles and substrates.
3. Implementation standard: JG158-2001
4. Reference dosage: 2-2.5kg/m3
5. Construction key points:
1. Base layer treatment: Caulking can be performed after the tile adhesive is cured for 24 hours. The gaps must be cleaned and the gaps can be pre-moistened to prepare the caulking.
2. Preparation of caulking agent: Reference ratio Water: Caulking agent = 1:4 (weight ratio). Mix the caulking agent and water in proportion using an electric stirrer (or manual) and stir evenly. Requirements Stir into a thick material without lumps or lumps, let it sit for 5-10 minutes, stir again and use.
3. Caulking construction: Use a hard sponge or scraper to press the slurry batch into the ceramic tile joints, so that the caulking material fully adheres to both sides of the joints, smooth the surface of the gaps, and then apply the slurry to the ceramic tile surface. Scrape off excess material and clean.
VI. Precautions:
The construction temperature is greater than 5℃; it is strictly prohibited to add sand, cement and other additives without permission; antifreeze type should be used below 0℃; the prepared mortar should be If used within 4 hours, it is strictly prohibited to mix the solidified mortar for a second time and put it into use; storage and transportation must be moisture-proof and rain-proof.
