Putty:

A decorative material used to level the surface of a wall, which is a thick paste coating and an essential product before painting. Apply on primer or directly on objects to remove uneven defects on the surface of the object being coated. It is formulated with a small amount of paint base, additives, a large amount of fillers, and an appropriate amount of coloring pigments. The main pigments used are iron red, carbon black, and Minghuang. The fillers are mainly calcium bicarbonate, talc powder, etc. It can be used to fill partially recessed work surfaces, or it can be scraped on the entire surface, usually applied to the surface of the primer layer after it has dried completely. Infants require good adhesion and no cracking during the baking process. When doing wall treatment! Firstly, clean up the floating ash and dust on the entire wall surface, then apply putty locally, grind it flat, and treat the board joints with gypsum expansion. After drying, apply a bandage, apply the first layer of putty, dry it, apply the second layer of putty, wait for the putty to dry completely, check, reapply putty, and reapply putty. This is the key time, make sure it is flat and not too thick. Wait for the putty to dry completely, polish it flat, and apply the first layer of paint. Then, reapply putty, polish, apply the second layer of paint, and after drying, apply the third layer of paint. Only in this way can the wall be of qualified quality, without cracking or peeling.

Mortar:

The bonding material used for bricklaying in buildings is composed of a certain proportion of sand and bonding materials (cement, lime paste, clay, etc.) mixed with water, also known as mortar or mortar. Mortar is made by mixing cementitious materials (cement, lime, clay, etc.) and fine aggregates (sand) with water. Commonly used types include cement mortar, mixed mortar (also known as cement lime mortar), lime mortar, and adhesive mortar. Mortar should have good workability, and hardened mortar should have the required strength and bonding strength. The workability of mortar is related to its fluidity and water retention, and is generally determined based on construction experience or through testing. The bonding strength of mortar increases with the increase of its grade, and is also related to the surface condition, cleanliness, moisture level, and construction and maintenance conditions of masonry. Therefore, before laying bricks, it is necessary to wet the bricks to enhance the bond between the bricks and mortar, ensuring the quality of the masonry.
