Waterproof eco-friendly anti-crack cement mortar

I.Brief Introduction：

Vanjoin Anti-crack Mortar(hereinafter referred to as Anti-crack Mortar)，is a kind of mortar which can sustain certain deformation without cracking, made from the antimitotic agent (composed by polymer emulsion and admixture), cement, and sand to a certain proportion. This is a new type anti-cracking material, has added our own additive with patent, perfectly combined with VANJOIN EPS composite sandwich wall panel and produce mutual acting force. It is an excellent eco-friendly material with high tensile resistance, easy for construction and resistant to freeze.

II.Features:

1.Anti-crack mortar and VANJOIN EPS composite sandwich wall panel has very strong mutual acting force, with high tensile resistance, and great anti-cracking effect.
2.Waterproof, freeze resistant, ageing resistant.
3.Easy construction, can directly construct with VANJOIN EPS composite sandwich wall panel

IV . Attention

1.Without any additives for the anti-crack cement mortar at site construction , strictly control the water ratio and time for plaster .
Mortar Powder : Water = 1:0.3 (Weight Ratio )

2.Can directly brush on “ Vanjoin EPS compound sandwich wall panel”, no need to brush the base coat .

3.Pay attention to moisture , rain-proof ,prevent insolate during transportation .

4.When storage of the anti-crack cement mortar , need to stored in a dry ventilated place, prevent from damp .

5. When use the anti-crack cement mortar , depend on the dosage of construction , not too much at one time . If happen to agglomerate , while has not used up of the mortar , the balance should not use any more .

6.Above 5℃ during storage & construction site . For some district Lower than 5℃ , need to inform in advance , Vanjoin will change the formula in time to meet your requirement .

7. Every time after complete of construction , to clean the construction tools and mixing equipment in time , thus not to affect next time use .
