One, how long does waterproof coating need to dry?
The setting time of waterproof materials varies with temperature and humidity. Generally, waterproof coatings can fully solidify and form a protective layer within approximately 24 hours in summer. If the air contains a high level of moisture, it may take longer than 24 hours to completely dry, and it is necessary to wait an additional day to ensure that the waterproof layer is completely solidified. In cold weather, waterproof materials typically require about 2 days to solidify. During rainy winter weather, it usually takes about 3 days for waterproof materials to completely solidify.
Two. How long can waterproof coating be tested for water permeability?
The water absorption test is typically conducted 24 hours after the waterproofing work is completed, and the water should remain in the container for at least 24 hours. For example, in bathroom waterproofing, after the waterproofing coating has dried, the floor should be filled with water to a height of approximately 5 cm, and the area should be inspected four times within one day. This includes the floor, walls, and the ceiling below, to check for any signs of water leakage or water stains at the joints between the floor and walls.
III. important Considerations for Waterproofing Material Application
1、Do not use putty powder arbitrarily. When the substrate is uneven or has gaps, you can use a small amount of putty powder to level and cover the surface. When using waterproof coatings, do not mix them with materials that have low strength and poor water resistance, as this can easily damage the performance of the waterproof coating.
2. Pay close attention to the mixing steps for the waterproof coating. Do not add water or any colorants to the waterproof coating. Waterproof coatings are composed of precisely mixed powders and inorganic materials. Adding water or other colorants will compromise the coating's properties, leading to air pockets or surface whitening. Before using the waterproof coating, it is essential to thoroughly mix it. When adding water, strictly follow the mixing instructions and avoid adding any colorants or paints arbitrarily, as this could cause a chemical reaction. If colorants need to be added before application, consult the manufacturer's instructions to avoid damaging the waterproof performance or achieving an undesirable finish color.
3. Proper use of construction tools. Some waterproof coatings can be applied as a waterproof protective layer using spray application. When using a spray gun, the waterproof coating must be applied evenly without any overspray or excessive thickness. Additionally, special attention must be paid to waterproofing in local corners and areas where walls and floors meet, to prevent the accumulation of coating materials.
