Construction methods and steps
1.Basic level processing: wall surface to keep certain roughness and strength, and eliminate the primary surface float ash, oil pollution, etc., if the wall surface is smooth, with liquid interface agent interface processing (loose or uneven need to root out, leveling processing), wait for dry rear can batch of fluor diatom gypsum.
2.Water ratio: the ratio of dry powder and water for the 1-0. 56 (adjusted according to request of climate condition and the construction personnel) (standard of drinking water)
3.Mixing methods: 90% of the total water consumption in the container to add water construction water, then pour diatom gypsum powder, soak a few minutes, reoccupy hand electric drill about 10 minutes, with another 10% of the water to adjust viscosity, can be used only to fully mix, and diatom gypsum mixture should be finished in 1 hour (lest) curing, stir the following times using the same container, container should be clean residual.
