Construction Techniques

Substrate treatment: The substrate must be free of dust, grease, any efflorescence and convex parts. Level major unevenness of surface using mortar. Thoroughly wet the substrate with clear water, but there is no water on the surface.

Preparation of the mortar: Volume of water is given in Certificate.   Add water to the mixing bucket, and then slowly add the powders while mixing with mechanical agitator until a homogeneous paste without lumps is obtained. The prepared mortar should be used up in 45 minutes. Never dilute with water again.

Application of mortar:
Exterior wall of building:Coat thickness of 3 mm to 5 mm.
a.After mixing evenly, apply the mortar on substrates as 2 to 3 coats according to the evenness of the surface, and the total coat thickness should be 5mm to 8mm. Press and smooth the mortar in the last step.
b.After setting, the next coat will be applied, and so on.
c.After the last application, allow the mortar to cure for at least 7 days after hardening.
Underground waterproofing projects：Coat thickness of 6 mm to 12 mm.
a.After mixing evenly, apply the mortar on substrates as 3 coats, and each coat thickness should be 2mm to 4mm. Press and smooth the mortar in the last step.
b.After setting, it will be constructed second times, and so on.
c.After the last application, allow the mortar to cure for at least 7 days after hardening.

Announcements

This mortar contains cement, which may cause skin and eye irritation. So please wear the necessary protective equipment during construction. If it touches your eyes, remove contact lenses and keep eyelids open. Rinse open eye immediately with plenty of running water. Seek medical advice if complaint continues.
