The surface treatment affects the firmness of the coating and the ground and the smoothness of the coating. It is also the key to epoxy floor construction. Epoxy floor has very high requirements for surface treatment. To ensure the quality of Epoxy floor, we must deal with the ground. This is to ensure that the floor is practical and beautiful, increase the useful life, and make the ground reach the best state. .
Why should the basement be treated before the construction of the floor?
1. Dust is serious. There are many sand particles on the surface of plains. Dust appears on the surface. The sandstone is grave, which means that the plain is not solid enough. The strength does not reach the minimum standard of epoxy floor paint construction above C25, and it is too loose on the plain. Epoxy floor paint construction will affect the adhesion of the floor paint and the base surface, and the sand and sand will also impede the flatness of the floor surface, which will easily lead to delamination and other problems on the ground floor, so the epoxy floor Before the construction of the trowel, the loose concrete layer must be removed.
2. There are many potholes, and the depth of each pothole is different. If there are pits and potholes of varying sizes, they need to be cleared and filled up. Otherwise it is easy to complete the construction of the floor. The place where the pothole is located becomes a hollow place. When high-strength impact work is performed, the floor may be easily broken.
3, easy to slippery plains, the presence of oil residue of the original oil pollution is the most common situation, and this situation is the greatest impact on the floor coating adhesion factor. The floor paint has the ability to penetrate, and the paint can penetrate through the fine pores of the plain, so that the bonding skill between the plain and the floor coating can be improved. However, the presence of oil contamination seals the tiny pore space, so that the floor coating can not be well bonded with the prime ground, and the area with oil pollution is easy to fall off.
Therefore, the dirty surface will affect the adhesive adhesion. Therefore, the epoxy floor paint needs to be treated before the construction, so that the characteristics of the epoxy floor coating can be highlighted, and the floor surface can be flat and seamless. Bright and beautiful effect.
How to properly handle the base surface before the construction of the floor?
First of all, look at the basic requirements for the floor construction:
Concrete strength requirements above C25;
It is recommended that the concrete should be filled with light;
The first floor is recommended to be waterproof and moisture-proof;
Flatness requirements 2M ruler maximum height difference is less than 3?
The construction temperature is generally above 5°C and the humidity is lower than 85%;
The newly poured concrete needs to be cured until the surface is fully dry before it can be constructed.
Base surface processing steps:
Initial cleaning
1. Clean up the garbage on the ground to be treated with a broom;
2. Where there is water, the water source should be cut off first, and surface water should be removed. Then, the ground should be dried. (If the ground to be constructed is on the first floor or in the basement, it should also be considered whether waterproof or moisture-proof treatment is required);
3, check the waterproof, moisture-proof effect. (a) Waterproof and moistureproof requirements are not met, and paint layers are not allowed. b. When testing, cover with a square meter of nylon film for every 100 square meters, and seal it with tape around the edges, and see if the color changes after 48 hours. Drops of water indicate that moisture has failed.)
4. Apply organic solvents (such as Tianna water, xylene, etc.) to the place where there is oil, and wipe it dry;
5. The place where there is paint or other unknown contaminants should be properly treated. The methods are: grinding, organic solvent scrubbing, etc.;
6, according to the actual situation, whether you need to do a clean;
7. If it is an old ground: Use a blade to remove the base surface (old paint, empty drum, and shell layer) and then perform sweeping and grinding.
Polishing the ground
1, using sanding machine fully polished:
Provides appropriate roughness for terrazzo bases and smoother dense cement bases.
1 Remove dust that is difficult to clean on the surface and roughen the base surface to enhance the adhesion of the coating to the ground;
2 Basically flatten the unevenness of the base surface to be treated, and play a leveling role.
Old ground renovation:
If the ground is an old ground, perform the following processing:
1. The rugged surface is filled with water-based rigid mortar for leveling and repair to achieve the leveling requirements of the ground;
2. To repair wide cracks and pits, it is best to use a quick-drying solvent-free epoxy resin coating to adjust the quartz sand;
3, for expansion joints, first clean the debris inside, and then use quick-drying solvent-free epoxy resin coated quartz sand repair;
4, for small cracks should be first cut into a V-groove with a grinder, and quick-drying solvent-free epoxy mortar for sealing treatment;
5, after curing with sandpaper polished flat, clean the ground.
