The structure of a house is usually reinforced concrete (RC) or metal roofing, which is prone to heat build-up and thus causes the surface temperature of the structure to rise and the indoor temperature to dissipate easily.
The use of heat-insulating coatings not only effectively reduces the use of air conditioning and saves electricity, but also has multiple effects of rust and water resistance, extending the life of the painted surface.
For metal roofs, container houses and other metal surfaces, the topcoat can be applied directly under normal conditions.
The function of primer is to increase the adhesion between the structure and the surface adhesive, seal the substrate to increase the alkali resistance and increase the coating rate of the top coat. The topcoat is the main waterproof layer. Please refer to the description of each product category for its characteristics.
If the surface to be painted is very rough, it may not be easy to paint and to penetrate, so the diultion is needed to solve such problem. Normally, no more than 10% of dilution is allowed to any waterproofing paint.
Blistering is due to the waterproofing material and the structure is not tightly connected, mostly caused by the following reasons:
1. When the structure is not fully dry before application.
2. The structure is not a plain ground.
3. Paint membrane is too thick.
Quick Solution:
If there are blisters, cut the blisters with a razor blade and reapply primer and topcoat.
When the waterproof layer is not yet broken, we recommended to clean the surface of the waterproof layer every 2-3 years and then reapply the topcoat with 1-2 layers.
