Oil-proof primer

Low viscosity and high permeability are mainly used in workshops with oil stains on the ground. The floor can play an isolation role and keep the floor away from oil stains. Make the epoxy coating firmly adhere to the base surface, easy to construct and cure quickly. Methods for treating oily floors:
Clean the floor and protect the machinery and equipment on the old floor.
. Burn the areas with obvious oil stains but do not burn the ground (it can also be removed manually)
. Use -% hydrochloric acid to flush the ground. The method is similar to the primer and scrape it with a knife to remove the oil. For heavy areas, you can push it a few more times. It is normal for a large number of bubbles to appear on the ground during this process. The hydrochloric acid will corrode the cement containing oil. Depending on the number of bubbles, you can apply it again (if there are many bubbles), but no more than two times at most. Preparation method of hydrochloric acid. Commercially available concentrated hydrochloric acid (% content). Pour about two kilograms of water into a bucket. During this process, be sure to pay attention to safety and ventilation. If hydrochloric acid splashes on your body, rinse it immediately with plenty of water and do not wipe it with a cloth.
Use alkali to wash the floor. Commercially available caustic soda (chemical name: sodium hydroxide) is about kilograms to kilograms of water. Scrape the floor once to neutralize the hydrochloric acid on the ground. In this process, the amount of alkali washing can be slightly greater than that of acid washing.
, wash the ground with a large amount of water to thoroughly wash away the acid and alkali of the ground. During this process, polish the ground with a water mill to remove the corroded cement and oil.
, wait for the ground to dry before proceeding with epoxy floor construction with good ventilation. If the conditions are bad for two days or a week, you can use an air conditioner or dehumidifier to deal with it.
During the process, pay special attention to areas with holes, large cracks, and hollows on the ground. Once acid penetrates and is not cleaned cleanly, it will be particularly easy to introduce problems and drying will be more difficult. It is recommended that these areas be treated before proceeding. Carry out inspections and use ** to burn out potholes with a lot of water. For larger areas or deeper ground cracks, sprinkle quicklime powder (chemical name: calcium oxide) inside after the ground is completely dry. It is often used as a desiccant and water-absorbing agent to absorb water. After an hour, use a vacuum cleaner to suck up the sucked powder. When it dries, it indicates that the water content of the ground is low and construction can be carried out.
