Omori guide | Summer construction considerations hit! ! !

(1) summer high temperature, windy, suitable for the doors and windows closed, batch scraping plaster

After the gypsum completely hardened after the window ventilation to prevent gypsum caused by wind

Cracking.

(2) gypsum-based products require a certain construction thickness (see each product for details)

The minimum construction thickness requirement) to ensure adequate hydration of gypsum, thus improving the stone

Paste strength; such as the case of water loss caused by too fast low strength can be used spray

The strength of gypsum can still be up after the gypsum is naturally dried in water for two times

Come on.

(3) when mixing to add water after adding powder, high temperature season need to add water as appropriate;

(4) in case of high temperature weather in summer, the wall surface is pre-treated with wine and water before construction, and the surface is not clear

Water can be used for construction.

(5) excessive humidity weather (humidity ≥60%) waiting for dry time to be delayed

Long, avoid the bottom moisture content is too high to lead to batch scraping finished putty foaming and later

The risk of paint mildewing points,

(6) during continuous construction, the mixing tools and containers should be cleaned in time to prevent hardening

The gypsum mixed into the fresh mortar causes the product to set quickly and crack.

(1) avoid construction in high temperature period and direct sunlight period, and control the ventilation intensity of the construction site. When the base surface is too dry and absorbs water quickly, it is recommended to brush the interface agent or pre-wet the base surface before construction (2) the temperature should not be higher than 35 °C in the weather, batch scrape two more than the putty powder should not be too thin or slurry scraping stir too thin. (3) in summer high temperature weather, putty dry and hard faster, in batch scrape putty at any time batch scrape, at any time light, shorten the time interval between the first and second batch (after the first batch, start the second batch immediately, and so on) . It is strictly prohibited to scrape the interval between the two batches too long to avoid drying too fast when the batch is closed again, there is a phenomenon of curling

(4) in the load-bearing wall lot before scraping putty to paint the wall solid treatment, and then scraping plaster lot, and then in the lot scraping putty to avoid in lot scraping putty bubble serious.
