Before the epoxy floor paint is painted, the quality of the face material is checked, so as to design a reasonable painting scheme and take some quality control measures according to the ground condition. What are the basic items of general inspection? A few days floor paint factory Anguang for everybody to explain: 1, ground smoothness: with 2 meters ruler check, record the gap value, mark the ground too high, in order to focus on grinding, the use of mortar repair too low.
2. Inspection of moisture content of base material: We should know how long the concrete has been cured, whether there is a waterproof layer in the bottom layer, weather conditions during the curing period, etc. Generally speaking, the maintenance period of 15 days upstairs on a fine summer day with good ventilation is OK. In winter, the maintenance period of rainy season should be longer. It usually takes about 1 months. Before construction, it is necessary to measure the moisture content of the base material by using the concrete moisture content measuring instrument. The following principles should be adopted to select the measuring points: A, the bottom floor (first floor); B, near doors, windows or external walls; C, part of the place where the concrete has been dipped after casting; D, water pipes, drains, etc. If there is no measuring instrument, the film covering method is also effective, the main point is that the film must not leak and must be tightly sealed.
3. Concrete strength inspection: mainly check whether there is sand on the surface of the concrete, whether there is local empty phenomenon, where the ground reinforcement material (mechanical grinding if not pay attention to easy damage to the machine), and then one by one marked and recorded. Special attention should be paid to the special strength of concrete when dealing with the ground grinding effect is not small, and before painting, it is very important to thoroughly dust down, after vacuum, solvent-free beech (dilution is better, conducive to increasing permeability) to make it as deep as possible penetration, reaction solidification after anchoring concrete.
4. Other aspects of inspection: because the epoxy floor paint construction needs a clean and closed painting environment, any details of the negligence may cause rework or defects, resulting in losses, so before the construction site to check the following aspects: A, doors and windows are intact, roof, water pipes, etc. whether there is a hidden danger of leakage; B, lighting, electricity If the facilities are available, if necessary, plan well; C, weather conditions during construction.
