Coating knowledge: the function of base treatment before floor coating construction

Core tip: in order to remove all kinds of foreign matters (such as oil, rust, dust, old paint film, etc.) attached to the painting surface before the construction of floor paint, provide a good substrate suitable for the painting requirements of floor paint to ensure the good adhesion of the paint film, the painting surface must be pretreated before the painting of floor paint People call the work of this kind of treatment as base treatment before coating The base treatment has the following functions 1 Ensure and improve the adhesion of the floor paint coating: the treated concrete base can make the floor paint primer penetrate more into the concrete surface, which plays a key role in the service life of the whole floor paint coating Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: in order to remove all kinds of foreign matters (such as oil, rust, dust, old paint film, etc.) attached to the coating surface before the construction of floor paint, provide a good substrate suitable for the coating requirements of floor paint, to ensure the good adhesion of the paint film, the coating surface must be pretreated before the coating of floor paint People call the work of this kind of treatment as base treatment before coating The base treatment has the following functions 1 Guarantee and improve the adhesion of floor paint coating: the treated concrete base surface can make the floor paint primer penetrate more into the concrete surface, which plays a key role in the service life of the whole floor paint coating Especially when there is oil and water on the base surface, it is difficult to form a continuous coating due to the poor compatibility of oil and water with the coating Even if a complete coating is formed, the adhesion of the coating will be greatly reduced, making the coating fall off prematurely When there is dust on the surface and direct construction without base surface care, the light one will cause pockmarks on the floor paint coating, and the heavy one may lead to large area falling off of the floor paint coating and shorten the service life of the floor paint Therefore, it is necessary to prepare for the establishment of a smooth, flat and beautiful coating and create a good foundation for the whole floor paint project 2 Create appropriate surface roughness: the adhesion of the floor paint coating to the concrete surface mainly depends on the mutual attraction between the polar molecules in the floor paint and the surface molecules of the substrate After the concrete is grinded by the floor grinder, the surface will become rough With the increase of the roughness, the surface area will increase significantly, and the attraction between the coating and the base surface per unit area will also increase exponentially At the same time, it also provides a suitable surface shape for the adhesion of the floor paint, and increases the mechanical toothing effect, which is very beneficial for the adhesion of the epoxy floor paint [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
