Which waterproof coating is best for summer bathroom decoration?
When it comes to waterproof coatings available on the market, one-component environmentally friendly polyurethane coatings are highly recommended by the Ministry of Construction. These coatings are ideal for small homes with many pipes and gaps because they can seal tightly around the pipe and ground, penetrate into small cracks, and do not shrink after drying. Compared to rigid materials like cement-based waterproofing, they offer better performance in such situations. When purchasing this type of coating, it's best to choose a reputable brand, as the cost is generally around 50-60 yuan per square meter.
Some domestic manufacturers of polyurethane coatings also provide professional installation teams. When buying the paint, you can request them to send experts to handle the application. To ensure long-lasting waterproofing, the coating should be applied at least three times. It's important to avoid applying the paint during rainy or humid weather, as this can affect the drying process. One-component environmentally friendly polyurethane coatings typically take about 3-4 days to fully dry.
What’s the best waterproof coating for bathroom renovation?
When using one-component environmentally friendly polyurethane coatings, along with cement layers and tile coverings, the total material cost per square meter usually doesn’t exceed 400 yuan. For a 5-square-meter bathroom, the total waterproofing cost would be around 2,000 yuan, excluding any additional costs for reconfiguring bathtubs or other fixtures.
After completing the waterproofing work, all toilet drains should be sealed, and a small "water wall" should be built at the bathroom entrance for a water test. The water level should be about 20 cm high. After 24 hours, if there's no leakage around the walls or floor, the waterproofing is considered excellent. If leaks are found, the problem areas should be identified and repaired promptly.
In addition, it's important to waterproof the walls as well. For better results, the walls in a typical bathroom should be coated up to about 30 cm in height to prevent water from seeping through the walls. The wall next to the bathtub should be treated even higher, above the top edge of the tub, ensuring complete protection against water damage.
