Before the construction of epoxy floor paint, the ground cleaning and oil pollution treatment should be carried out. According to the degree of oil pollution, including erosion life, oil penetration depth and pollution area, the following treatment should be done: in the epoxy floor project we contacted, the proportion of old ground renovation and oil sand on the ground accounted for 5/2, where the surface is covered.“ Oil stains on the ground are the most troublesome and difficult to deal with. How to construct epoxy floor paint on oily ground? Usually before the floor paint construction, the first thing is to clean the ground, especially some oil stains or chemicals on the ground must be cleaned up. Otherwise, these oil stains will seriously affect the quality of the floor construction, if serious, it will also cause the floor paint to fall off, bubbles and other issues.
1. Thin oil contamination layer (d2mm) can be removed by milling machine as a whole.
2. If oil contamination only exists on the surface, it can be removed by cleaning agent or solvent.
3. Thick and heavy oil contamination layer: re-pouring concrete after whole removal or whole removal by milling machine;
4. Local oil pollution can be removed by gun.
5. Scrub the surface with absolute ethanol or dibutyl ester - degrease.
6. Mix flour and sawdust, stir-fry and spread on the surface for at least one day - oil absorption.
7. Drill a certain number of small holes evenly on the surface with electric tools, 20 millimetres - - to form a glue nail.
The quality of construction not only requires that there should be no errors in the construction process, but also that the ground should be cleaned up before construction, so as to ensure the quality of the ground and avoid unnecessary problems in the future use process and affect the normal use.
