Product Introduction

Acylic polyurethane waterproofing paint coatings for steel is recommended by the ministry of construction of new green waterproof coating, is two-component waterproof coating composed of organic and inorganic powder ,it is a kind of new type waterproof material that have high elasticity of organic materials and good durability advantages of inorganic material. After coating it can form waterproof coating of high strength and high elastic, and can be prepared according to the requirement of color coating.

Features:

1. Construction on the surface of the base in wet or dry a variety of materials

2. The coating has high strength tenacity, water resistance, weatherability, excellent durability

3. Can add pigment, forming a color coating

4. Non-toxic, tasteless, no pollution, construction safety supervision, short construction period

5. Construction at the top of the elevation, slope and top surface does not flow

6. With the base and cement mortar and other materials solid paste

7. High temperature resistance can reach 40 degrees

Application:

All kinds of old and new buildings and structures(example: roofing of building, underground, outer wall, bathroom, tunnel and bridge pool, etc)waterproof engineering all can use.

Usage:

1.The base surface must be smooth, solid, clean, no water, no leakage, uneven place must first be leveling, the leak must first plugging treatment and Angle of Yin and Yang should make arc Angle.

2.According to the provisions of scale material, such as need to add water, first add in liquid, with the stirrer stirring to join. Fully stir to aggregate does not contain material( stirring time more than 3 minutes, preferably without manual stirring).The weight ratio of the layer coating: liquid material : powder: water = (Ⅰ)10:7:10 , (Ⅱ)10:12:10, the weight ratio of the lower, middle, and top coating: liquid material : powder: water = (Ⅰ)10:7:0-1 , (Ⅱ) 10:12:0-2, the top coating can add pigment to form color layer. Within the prescribed scope of water, slope, the top surface or facade construction without or with small amount, plane construction should add some more.

3.Select the appropriate tools (roller, brush or scraper, etc.), in accordance with the corresponding method, according to the bottom→ the lower→ the upper step by step to complete.

4.Protective layer or decorative layer construction, must be 2 days after the completion of the waterproof layer, in order to facilitate the construction of plastering mortar, after the final time coating again of the waterproof layer, then immediately sprinkle medium-coarse clean sand coarse sand in the clean immediately. Liquid: powder =10:20-30 powder tune into putty shape, but also can be used as adhesive, sealing material.

Transportation and storage :

To prevent the sun and rain, keep the packaging intact

The liquid material should be stored in the shade place above 0 degrees ;The powder should be stored in a dry place, shelf life is 6 to 12 months

Matter need attentioning:

1.If paint (especially primer) have precipitation should stir to mix well at any time.

2.Try to uniform coating and cannot have local deposition, and require more rolling brush a few times to adhesive sealed and not see the bubbles between coating at the grass-roots level.

3.Each layer of coating must be in accordance with the provisions dosage of picking materials, will not be too thick or too thin, if the thickness of waterproof layer is not enough, can add one layer or several layers, coated with total number of not less than 3 layers.

4.The time interval between each layer base on once before the coating dry solid non stick (usually take three to six hours, when the low temperature, high humidity and poor ventilation, dry solid time take longer, and otherwise shorter)

5.Construction not below 0 degrees or in the rain,and should not be in very damp and without ventilation environment construct, it will affect the film.
