How to ensure the construction quality of metal (non-metal) diamond abrasion-resistant floor paint? (1) To fully understand the importance of epoxy floor construction, "Seven parts of materials, three parts of construction" is a long-term expression of the importance of construction to the use of coatings in the paint industry. This is especially true for epoxy wear-resistant floors. From the use point of view, epoxy wear-resistant floor has some special performance requirements, such as long-term bearing dynamic and static loads. It has been subjected to long-term friction and shear force, long-term corrosion of various corrosive media such as acid, alkali, etc. In addition to the special requirements for the performance of materials, these characteristics have stricter and more specialized requirements for the construction quality. 对此必须具有充分的认识，从基层处理的打蜡抛光的每一道工序都是应该严格对待，慎重处理，绝不能大而化之，以免生产施工质量问题。
We must have a full understanding of this. Every process of waxing and polishing from the grass-roots level should be treated strictly and handled cautiously, so as to avoid the quality problems of production and construction.
(2) Attention should be paid to the quality of grass-roots units and the treatment of grass-roots units.
The quality of concrete base significantly affects the quality of epoxy wear-resistant floor.
For example, the surface strength, smoothness, maintenance, surface acidity and alkalinity, the structure and moisture content of the base will affect the quality of the floor, and even lead to construction failure in serious cases.
For example, some construction enterprises pay less attention to the inspection and level of the grass-roots during the construction, and pay less attention to the treatment of the grass-roots. As a result, various quality problems appear soon after the construction of floor paint.
Therefore, strict inspection and treatment of concrete base is the basis of construction of high-quality epoxy wear-resistant floor.
(3) Pay attention to the treatment of grass-roots surface
It is generally believed that concrete is porous material, and its bond with epoxy resin material is very strong.
But this is not exactly the case, because there are many other factors.
In fact, only after the correct treatment of the concrete base, coating can produce good bond with concrete.
Generally speaking, in the construction of concrete ground, due to the vibration technology of concrete, the surface layer is enriched with cement slurry to form a dense surface layer of cement slurry.
The surface is smooth, smooth, compact and has small roughness.
Another case is that the surface concrete loses water quickly during the curing process.
Cement hydration can not go through completely, so the strength of the surface layer is low and the surface hardness is low.
Therefore, in order to construct high-quality epoxy wear-resistant floor, it is necessary to remove the surface layer.
The epoxy wear-resistant floor can be directly bonded to the solid concrete base, which is also easy for epoxy resin to penetrate into the porous concrete layer.
(4) Attention should be paid to improving the working hygiene conditions in construction
Improving the working hygienic conditions of construction is of great significance to the construction quality of epoxy wear-resistant floor paint.
Usually, the construction of solvent-based coatings is dirty, tired and harmful to health. Especially in small area and poor ventilation conditions, the solvent concentration in the construction environment is very high.
In such an environment, work is easy to fatigue, and then affect the quality of construction, but also easy to cause fire. Therefore, measures should be taken to ventilate.
Measures should also be taken to improve other factors that are likely to cause rare problems in construction.
(5) Construction quality management
In the construction process of epoxy wear-resistant floor paint, there should be full-time quality management personnel to manage every process in the construction, to ensure that the next process is carried out after the process is qualified.
Construction Explanation of Epoxy Wear Resistant Floor Paint
(a) Cleaning: before cleaning, all the other materials in the area should be moved first, and then the oil dirt should be cleaned with special cleaning agent.
B) Grinding: grinding with a large diamond grinder to flatten the original surface slurry so as to enhance the adhesion of the new floor paint and clean it with a vacuum cleaner;
C) epoxy primer: apply the Farley brand one component once (depending on the oil absorption on the cement base surface) to strengthen the base surface, seal the capillary holes on the cement surface, and enhance the adhesion;
D) Reinforcement of concrete floors:
Where the wear is large and the strength of concrete can not meet the requirements, concrete reinforcement must be carried out. 10 holes per square metre should be drilled by electric hammer with a depth of 15.3%.
The hole is then filled with epoxy resin to infiltrate the material into the concrete and enhance its adhesion.
E) Secondary grinding: grinding with a large diamond grinder, then cleaning and dust removal;
F) Scrape the floor paint putty twice, dry it flat or polished flat, vacuum cleaner clean the surface dust;
G) Epoxy floor paint: 1:1 blend of component A and B of Farley brand floor paint, roll-coating on putty layer (usually twice) to make the color consistent;
H) Overlay varnish: cover the floor deck component (varnish) once, enhance the hardness, endurance, strength, moisture-proof and waterproof, increase gloss;
I) Maintenance: After completion, it is generally necessary to maintain for 3-7 days before it can be used (large area of monomer needs to be segmented, and expansion joints should be segmented during the maintenance period).
