  • Detail

The exterior wall putty powder is finely processed with inorganic cementitious materials as the base material, combined with bonding materials and other additives. Its outstanding characteristics are high bonding strength, water resistance, alkali resistance and good construction performance. As the surface leveling material of outdoor buildings, it can be used once and for all. It avoids cracking, foaming, chalking or falling off

exterior wall putty powder is finely processed with inorganic cementitious materials as the base material, combined with bonding materials and other additives. Its outstanding characteristics are high bonding strength, water resistance, alkali resistance and good construction performance. As the surface leveling material of outdoor buildings, it can be used once and for all. It avoids cracking, foaming, chalking or falling off. The following editor will introduce the use method of exterior wall putty powder and the characteristics of exterior wall putty powder

application method of exterior wall putty powder

dosage: theoretical consumption value: 1-1.5 kg/m2 (putty thickness 1 mm)

mixing: the amount of water added shall be subject to the construction consistency. After mixing evenly, place it for 10 minutes, and then mix it. (Tips: putty powder cannot be mixed with inferior white latex to avoid adverse reactions)

surface treatment: the wall surface is smooth or new building materials, such as gypsum partition board, polystyrene board, paper gypsum board, etc., need to be treated with interface agent

scraping and leveling: due to the high strength of the putty, it should be leveled with a scraper when the putty is in a semi dry state (gently pressed by hand without deformation)

storage: store in a cool and dry place with a shelf life of 12 months

characteristics of exterior wall putty powder

1. Good workability, easy to scrape, easy to flatten, no curling, no fuzzing, and burnable after curing

2. Strong bonding force ensures firm bonding with the base surface, without hollowing and peeling

3. Good water resistance, no foaming and pulverization when encountering water for a long time

4. Good alkali resistance has strong adaptability to the alkalinity of cement mortar and concrete new wall base

5. No pulverization. The putty layer after scraping shall not appear pulverization after curing

6. Meet special functional requirements, such as high elasticity, old ceramic tile renovation treatment (directly scraping on the ceramic tile surface) and base treatment of metal paint construction

construction process of exterior wall putty

1. Construction preparation

preparation of construction tools: prepare the construction shovel, scraper, sandpaper, etc. for use

material preparation: check the performance quality of putty for construction, whether there is caking, mildew, etc. If it is powdery putty, it should be mixed evenly with water according to the proportion of the manual, and stand still for use

base course inspection: check whether the surface of the construction base course is firm, whether there are cracks or hollows, whether there is dirt pollution, and deal with it accordingly

2. Grassroots treatment

clean up stolen goods and pollutants

local leveling. Fill the pits, level the projections, and fully putty or polish the honeycomb and pitted surfaces

drying degree of base course. The base course shall be cured as necessary, and it shall not be too wet, but it shall not be too dry

3. Apply putty

if the base course is too dry or has strong water absorption, it is best to use sealing primer for sealing, otherwise it will affect the adhesion of putty

the putty shall be applied with a trowel from top to bottom or from right to left, and the spatula shall be scraped at an angle of 30% with the base surface. Each time of putty cannot be scraped too thick, which is easy to crack, fall off and other defects. Generally, one layer of exterior wall putty is about 0.5~1.0mm

putty is usually applied twice, and the interval between two times of putty cannot be too short. The second putty must be applied after the first putty is dry

do not scrape back and forth too much when applying putty, so as to avoid curling, falling off or extruding the rubber in the putty, and sealing the surface is not easy to dry

when applying putty, pay attention to the method, fill it up, and scrape the putty around to minimize the traces of putty

4. Polishing of putty

after the putty base is dry, polish it with sandpaper. The thickness of sandpaper depends on the type of putty. Coarse sandpaper is used to polish hard putty and clean the base course, medium sandpaper is used to polish ordinary putty, and fine sandpaper is used to polish smooth putty

sanding putty is usually wrapped in sandpaper on the pad of sanding block, and the pad is pushed back and forth. It is not allowed to grind with sandpaper pressed by oneortwo fingers, so as not to affect the flatness of grinding

check the flatness of the base course. It is qualified if there is no significant scratch, no rough feeling, and the surface is smooth. The original loose base course of the old wall should be eradicated first, and the floating ash should be removed. If it cannot be eradicated, the interface should be thoroughly cleaned with detergent. After the strong surface is cleaned, it shall be approved according to the construction method of putty

editor's summary: This is the introduction about the use method of exterior wall putty powder and the characteristics of exterior wall putty powder. I hope it will be helpful to you. If you want to know more, you can pay attention to information
