First, the fire coating in the coating before the paint should be sufficient to stir the average, such as paint is too thick when the amount of water can be too concentrated to be painted, can not flow can be. Second, the choice of spraying methods need to select the specific circumstances, such as the construction of the tunnel is required to take the spray method of construction, although some paint waste but save manpower costs also shorten the construction time, but if the construction object is Indoor, you need to take the method of artificial smear brushing, not only can reduce the use of paint, but also to prevent the paint splashed to other places, to avoid the construction after the clean-up work. Third, the thickness of the coating requirements of the fire coating, the first time the thickness of the coating to cover the appearance of the base is appropriate, the individual does not exceed 1mm; in the previous coating before the practice can be carried out before the next painting; Increase the thickness of each brushing, but not flow is appropriate.
The surface clean, spray and brush can be
1, before the construction must be on the base (coated material) to clean up, remove the ash, oil and paint to be debris. Wood base should reach the natural dry state, water content <10%. 2, stir even after brushing to ensure the construction quality and product performance. 3, should be above 5 ℃, within 24 hours after construction to avoid rain. 4, the coating is generally coated with two layers, if necessary, can be coated with three layers, or cover the light again, Tu finished the first time, the natural dry after the next layer of construction. Every time the brushing surface shall not be leaked. Per square meter with the amount of ≥ 500g, to a fire safety standards. 5, brushing process using brush, spray or roller, brushing evenly. Brush the direction to be consistent, do not cross or repeatedly brushing. Note winter construction should be above 5 ℃, summer should be below 35 ℃, to avoid freezing or overheating.
