3. The time interval between the layers before a layer of paint dry solid, non-stick prevail (generally 2-6 hours, the site temperature is low, humidity, poor ventilation, drying time is longer;Otherwise shorter) Try to increase the interval.
4. If the thickness of the waterproof layer is not enough (especially the facade construction), one or several layers can be added.
5. The waterproof layer of outdoor and easy to touch and tread parts should be a protective layer.The construction of the protective layer or decorative layer shall be carried out 2 days after the completion of the waterproof layer.When applying mortar, in order to facilitate construction, clean medium coarse sand can be sprinkled immediately after the last coating of the waterproof layer, but the sand is only limited to the facade.
