Batch of scraping 1 square meters need to use 8-10 kg (10 mm) wet film thickness.
Above amount does not include losses are for reference only, actual usage because of construction method of wall roughness.
Suitable thickness of the leveling, the metope of not too smooth, one-time leveling thickness shall be not less than 5 mm.
Suitable for the mixing proportion of: gypsum powder: water = 1-0. 55 weight ratio, consistency will be subject to specific group of scraping the convenient.
Dot a pay-off, being: in strict accordance with construction drawing size requirements for grassroots pay-off, dot;
Screed: being in accordance with the pay-off and the position of the dot, strictly carries on the construction of the screed, each ash reinforcement should be indomitable spirit, not steal to reduce ash reinforcement quantity;
Kok: being is across the hall, protect horn in window edge parts of construction, to ensure that the vertical, horizontal, founder; Double reinforcement, reinforcement: check with 3 m by poles screed flatness, laser out to check the perpendicularity of the rod, square check Angle founder degrees of Yin and Yang, laser rangefinder inspection room, studio, founder of the flaws of the rod position make rectification tag, timely organization personnel repair;
Adjust the machine being water level and pressure of spray equipment, ensure the machine out smoothly, stucco gypsum not fall;
Spray spray machine, being screed side spray on metope, stucco gypsum spray screed thickness and slightly higher than the screed position, ensure the slurry.
Matters needing attention
A mixture mixing process, being banned from other than water powder and binder.
For the smooth surface of the concrete, shall be made in advance wool processing, in order to improve the adhesion strength of the base with this product.
When the first batch of scraping, thin can be conducted on grassroots first batch, the thinnest of no less than 5 mm and continuous feeding, which facilitates air discharge, enhance gypsum and the rapping at the grass-roots level.
Shear wall being recommended to brush a pomegranate source development, special interface agent, prevent foaming empty drum.
Nurture individual parts if the first batch of scraping the plaster surface appear white powder off phenomenon, usable brush dips in just the right amount of water, to hydrate the white surface, the water not to drip and does not destroy the gypsum layer is advisable.
Oblivious of avoid by all means to allocate after initial setting and hard gypsum mixed water again.
Being finished product suggest a use after opening, products should be sealed, the storage and use as soon as possible, avoid to be affected with damp be affected with damp effect use effect.
Summer high temperature weather construction, brick, concrete wall, ceiling plaster, water should be sprayed with 1 to 2 times, surface is flowing water construction can be achieved.
Continuous rain or cold weather, the appropriate extension of the gypsum layer maintenance time avoid caused by exorbitant as the moisture content of the underlying surface putty foaming and late coating yellowed.
Do in windy day construction, it is recommended that close the doors and Windows, avoid rapid water loss caused by air flow too fast plaster surface impact strength.
