water-closed test is a one-step verification step for waterproofing projects. If the water level drops severely, it means that there must be a leaking problem. Then this waterproof construction needs to be redone or remediated. But not falling in the water level does not mean success. Another situation is that the waterproof layer peels, skin blisters, and even dissolves. There is no water leakage problem, but we cannot pretend to turn a blind eye to the waterproof layer. Such waterproofing effect will definitely not last long.
First, let’s understand the reasons for dissolution, peeling and bubbles when closed water:
1. The base layer is improperly treated, the leveling layer is sandy, and it is not well bonded to the paint, so it is peeled off;
2. The construction process is not carried out according to the specifications, resulting in peeling;
3. Waterproof coating waterproof coating purchases inferior products, but the adhesion strength is insufficient after applying it;
4. The waterproof coating is not completely dry. If the coating film is not strong enough, the water will be closed, which will cause the undried surface coating film to be dissolved by water. Water will penetrate into the coating film and water will be soaked in water. Over time, it will peel and bubble. How to remedy the dissolution, peeling, or blistering of
?
1. Purchase "three haves" (with production date, factory name address, and quality warranty) brand waterproofing that meets national standards;
2. The original waterproof coating layer can be removed, and the coating should be crossed perpendicularly according to the direction of each layer, and the coating should be applied 2 to 3 times, and the total thickness of the coating is 1.5 to 2mm for construction.
3. Strengthen indoor ventilation conditions and accelerate indoor air circulation, which is conducive to the volatility of moisture in the coating film and improve drying speed.
4. It is recommended that the water-closed test be performed 48 hours after the last coating is completely dried.
Home decoration waterproofing involves many aspects, such as base layer, materials, house structure, etc., but in addition to these objective factors, it is often caused by the carelessness of construction workers or the rush to build time.
