Refractory spray paint is a kind of refractory material, so how should it be used? The following editors will briefly introduce you:
1. The concrete surface should be deashed and decontaminated before construction.
2. Coating mixing: Dosing according to the ratio of water: coating = 100: 120. First add water to the coating according to the ratio and stir well. The prepared coating should be used up within 2 hours. Due to different construction equipment and weather conditions, water can be added as appropriate.
3. Construction method: Construction should be carried out above 5 ℃. The first pass should be sprayed, and the thickness is preferably about 3-5mm, and the thickness of each subsequent pass is about 3-5mm, until the fire protection design requirements are reached. The construction interval between each pass is not less than 24 hours.
4. Surface decoration: If spraying construction is used, the appearance of the coating is a uniform grain surface, and it also has sound absorption function, and it is generally not smoothed. When it is really necessary to smooth the surface, it should be carried out after spraying. When surface decoration is required, other decorative materials can be sprayed (brushed) on the surface of the fire-resistant coating.
The above is the knowledge about the use of refractory spray coatings. Do you also have a lot of gains like Xiaobian? I hope the above can help you make better use of refractory spray paint.
