Bathroom waterproof coating purchase tips
When evaluating the quality of bathroom waterproofing, the first thing to check is the quality of the waterproof coating. There are typically two types of waterproof materials available in the market for home use. One is liquid waterproof coating, such as polyurethane and polymer composite coatings. The other is powder-based waterproofing material, like waterproof rubber powder or sealing agents. How can consumers choose the right waterproof material for their bathroom to ensure a safe and effective waterproof layer?
Introduction to Bathroom Waterproof Coating
Liquid waterproof coatings mainly include polyurethane, tar-based, and non-tar-based options. Non-tar type coatings are the most commonly used on the market. They use non-tar materials as curing agents, such as asphalt-based agents with additives and fillers. These coatings are usually divided into two parts: Part A is the curing agent, and Part B is the main component. They offer stable quality, low pollution, good aging resistance, strong adhesion, and low water absorption.
Non-tar waterproof coatings are widely used for bathrooms and kitchens. Before application, they need to be mixed evenly with a diluent, then applied to a properly treated surface. During construction, it's important to control the thickness of each coat—typically more than 2mm is sufficient for effective waterproofing. After testing for leaks, a cement mortar protective layer should be added over the waterproof layer to prevent damage from sharp objects that could cause future leaks.
How to Choose the Right Waterproof Coating
(1) Consider the local temperature range and choose a coating that is suitable for either high heat resistance or low-temperature flexibility. In hot areas, opt for coatings with high heat resistance to avoid melting. In colder regions, select flexible coatings that won’t become brittle in the cold.
(2) Based on the deformation of the base, structural design, annual and daily temperature differences, and vibration factors, choose coatings with appropriate tensile properties. For roofs with significant structural movement, use coatings with high elongation, such as Leibangshi’s flexible JS waterproof coating.
(3) If the roof is exposed to sunlight, choose a coating with UV and heat aging resistance to extend its lifespan.
(4) If the roof slope exceeds 25%, avoid using coatings that take too long to dry.
Combining Two Materials is Essential:
When purchasing non-tar waterproof coatings, they must be bought and mixed together. These coatings have a large market share, and many well-known brands offer them through specialty stores, making them easily accessible for consumers.
Experts advise that when buying non-tar waterproof coatings, consumers should also purchase the correct amount of thinner. Different manufacturers may have different formulations, so the amount of thinner needed may vary. Most thinners are sold in bulk, and their quality can be hard to control. Reputable manufacturers usually sell these coatings in sets that include the necessary thinner, offering various grades for consumers to choose from based on their budget and renovation needs.
