One of the most important aspects of interior decoration is waterproof work. When we are doing waterproof work, we must choose the right materials. Today, Xiao Bian will give you an introduction to the knowledge about waterproof materials and hope to help you.
Waterproof coating is the necessary position in the home decoration. After curing, it will form a layer of coating without seams to prevent water from immersing and leaking paint. Waterproof paint is mostly thick liquid at room temperature, but after brushing, it will form a tough waterproof film on the base layer. Applying the waterproof coating on the surface of the base layer can play a role in closing the gap microhole and preventing it. Water enters the gap.
What kind of waterproof coating?Most of the waterproof coatings on the market are organic waterproof coatings. Organic waterproof coatings can be classified into three types: water-emulsion waterproof coatings, reactive waterproof coatings, and solvent-based waterproof coatings.
Affordable water-based waterproof coatingThis kind of waterproof paint evaporates through the water and passes through the process of solid particles approaching, contacting and deforming. The paint dries slowly. The density of a film is lower than that of a solvent-based paint. Generally, it is not suitable for construction below 5°C; the storage period is generally not More than half a year; can be constructed on a slightly damp grassroots; non-toxic, non-combustible, safer in production, storage, transportation, and use; easy to operate, environmentally friendly; lower production costs.
The more expensive reactive waterproof coatingThis type of waterproof coating chemically reacts with the corresponding substances through a liquid polymer prepolymer and becomes a conjunctiva; a thick coating film can be formed at once, without shrinkage, and the coating film is dense; the two-component coating needs a 1:2 spot on the spot. Accurate, uniform mixing to ensure quality; expensive
Fast drying solvent-based waterproof coatingThis kind of coating is volatilized by the solvent, and the film is formed by the contact and lap-joining of the polymer molecular chain; the paint dries quickly, the conjunctiva is thin and dense; the production process is relatively simple, the coating storage stability is good; flammable, explosive, Toxic, should pay attention to safety when producing, storing and using; Because the solvent volatilizes quickly, the environment is polluted during construction.
After reading the classification of waterproof materials, many consumers will ask, then which one is suitable for me? First of all, the selection of different waterproof coatings for building structures will have different priorities. If wood or metal substrates are used, solvent-based coatings are preferred. If used for concrete or cement mortars, polymer-based waterborne coatings are used.
In addition, the use of different space will also have different requirements for waterproof coatings. If it is used in the bedroom, it requires a strong adhesion of the paint, preferably a certain degree of decorative. If used in a wet place such as a bathroom, the paint requires mildew-proof and easy-to-clean functions.
After the waterproof project is done, fill the water-requiring part with water, and see if the water leaks into the wall after one day. In order to test whether the quality of waterproof material and waterproof construction is in place.
Edit reminder: Finally remind everyone that waterproof coating just like other decoration materials, to pay attention to environmental protection, so as not to affect human health, if you do not know which one to trust, choose a large brand, good reputation, so as not to Workshops benefit from it.
