耐酸碱封闭底漆
introduction:
this paint is a kind of water-base functional seal primer mixed with acrylate emulsion, special mildewproof and anti-algae agent and filler. it enjoys excellent permeability resistance, pulverization-resistance and alkali-resistance.the adhesion between topcoat and metal will be improved. the paint can improve the fullness of the film. it is applied to the surface of the concrete and mortar.
metal treatment
1. be sure that the surface of the metal is complete and clean.
2. remove the grease, mold and dust on the surface of the metal.
3. remove the loose part on the surface of the metal and it dry and firm.
way of construction
1. ph of the wall is below 10. moisture content of the wall is below 10%.
2. when the temperature on site is below 5℃ and the relative humidity is more than85%, don’t work.
3. the paint don’t need diluting. if the viscosity is too high water that is less than 5% can be added.
4. way of painting: brush painting, roller coating, spraying
