One、What should be used as a base for seashell powder?
Putty.
Shell powder wall materials are suitable for various substrates, including concrete walls, wood panels, gypsum boards, PC boards, aluminum composite panels, glass, and steel walls. Internal walls require a higher finish than external walls, so a higher level of smoothness is typically required, and therefore, patching with putty powder is common.
Putty is a decorative material used to create a smooth surface on walls. It is a thick-consistency coating and is an essential product to use before painting.
Putty can fill localized depressions on working surfaces, or be applied to the entire surface after removing existing coatings. It is typically applied to the surface of the primer coat after the primer has dried. Putty generally offers excellent waterproof properties, high durability, and strong leveling properties.
Two. important considerations when applying seashell powder
1. Prepare the construction site thoroughly. Apply a primer or oil to the substrate surface before application to effectively prevent cracking and color variations in the finished surface.
2. Strictly add the required amount of tap water according to the specified ratio, and thoroughly mix with an electric mixer (add warm water if necessary in winter).
3. Avoid direct sunlight exposure during construction to prevent affecting the construction quality.
4、It is not recommended to construct in environments below 0°C. The construction temperature should be ≥5°C, and the humidity should be ≤85%.
5、Shell powder wall materials are one-component, and generally require 24 hours of maintenance in summer after completion, and 48 hours in winter.
6. During maintenance, avoid collisions. Any collisions during maintenance will result in seams, which will affect the overall aesthetic appearance.
