Then the basic mix of putty will be got through orthogonal experimental design. The basic material in this paper is cement and coarse whiting, talcum powder and quartz powder are the fillers. Exterior wall putty is leveling material of the protective layer, and putty fitting for external thermal insulation system should have a high bonding strength, good performance of crack resistance and excellent resistance to water. However, more common problems of construction quality arise with the increase of project amount.

Clean the hardened materials mechanically.With the rapid development of construction industry, the amount of architectural coatings, especially exterior wall coatings, is growing year by year. The bonding agent will perform as a surface enhancer and a curing compound that will naturally disintegrate with time.Ĭlean all tools immediately after finishing by water. However, when using Vetonit Putty WR as a final finish, it is recommended to apply a single Bond Pure coat. Vetonit Putty WR is self-curing, and it does not require water treatment. Use a flat trowel to level the material to a smooth finish.Īpply a second coat if necessary once the first coat initially sets.Īfter applying Vetonit Putty WR, it is recommended to apply one coat of alkali-resistant primer followed by two coats of acrylic emulsion paint or other suitable coatings. Generally, apply Vetonit Putty WR is in single or double coats.Īpply Vetonit Putty WR to the substrate by pressing the putty firmly onto it. Do not add water once the mixed filler mortar starts to stiffen or harden.

Follow the same mixing procedure as above. When required, add 1 liter of Vetonit Bond 2 to the mixing water and adjust the water requirement for each 20kg bag of Vetonit Putty WR accordingly. Mix small batch quantities manually for approximately 1-2 min, or until achieving a when a homogenous mix.

Leave the mixed material to stand for 10 min and briefly remix without adding water. Mix for 3-4 minutes until achieving a uniform, lump-free consistency. Add the powder to the water and mix with a mechanical plaster mixer or a low-speed electric drill fitted with a suitable paddle. For mechanical mixing, add to the mixing container 7.6-8.8 liters of water for each 20kg bag of Vetonit Putty WR.
