1.Description:

Metal roof waterproof coating is a one component water-based waterproof coating made of acrylate copolymer lotion as the matrix, high-quality pigments, fillers and selected functional additives.

2.Application range:

Metal roof waterproofing project

3.Reference dosage

Under normal conditions, when the thickness of the waterproof layer coating is 1.0mm, the recommended dosage is 2.3-2.5kg/㎡ (the actual dosage depends on the base condition and coating thickness).

4.Product features:

(1) Excellent high tensile strength,high bonding strength,large elongation, and perfect fracture resistance.

(2) Perfect low temperature flexibility : Flexible at low temperature, no fracture when temperature at -30℃/180 degree.

(3) Good aging resistance: outstanding outdoor durability and ultraviolet resistance.            

(4) Corrosion resistance: Highly resistant to acid and alkali, restraining mustiness and algae growth.

(5) Perfect breath ability, no bubbling, non-scale,no hydrops .

5.construction technology

(1) The metal roof base requires rust removal and degreasing treatment, the surface is clean, and the metal plate interfaces and detailed nodes should be treated with an additional layer. The additional layer method is: firstly fabric and secondly application. The additional base material should be (30-50) g/㎡ polyester fiber non-woven fabric.

(2) Acrylic waterproof coating can be applied on large surfaces by roller brushing or mechanical spraying. The coating should be applied or sprayed in layers, and the coating should be even. The coating should be applied after the previous coating is dry and film-forming (no stickiness when touched). The coating direction should be changed alternately with each application, and the overlap width of the same layer of coating should be 30~50mm.

(3) The joint width of the paint waterproof layer should not be less than 100mm, and the joint surface should be cleaned before coating.

6.Limitation

(1) Not subject to any traffic and must be protected by protective screed or polystyrene board.

(2) Do not apply with high consumption than recommended amount.

7.Safety Precautions

We recommend the use of protective gloves during application.if there is contact with eyes and skin,wash immediately with plenty of water.Seek medical assistance immediately.
