One Component Waterproofing Polyurethane Coating 


Product Description

Single-component moisture-curing pure polyurethane waterproof coating is a kind of liquid polymer waterproof material, suitable for dry and wet base surface construction, solidified into high tough and elastic, non-toxic and tasteless waterproof film after coating. It is a new type of environmental friendly waterproof material without solvent.


1. One component,simple construction,short construction time

2.Non-toxic,odorless,at present,It is a substitute of solvent waterproof coating which is often used.

3.Carry out construction directly on many kinds of wet and dry material’s base.

4.High solid content,good elongation performance

5.One component,simple construction,short construction time

Package And Storage


1.The package is barrel,25kg/barrel,5kg/barrel

2.The product should be stored at cool place.

3.The shelf life is one year.


 It can be used in the waterproof for all kinds of substrates of roofs,kitchen,washing room,basements,tunnels,bridge,pond, reservoir,swimming pool.

Substrate Treatment

Make sure substrates are leveled, firm, clean and no visual water. Any cracks should be repaired first. The leakage must be treated firstly,Internal & external corners should be curved shape.

Material preparation

Opening the bucket and observing whether the paint is precipitated, you should stir evenly firstly and use it if there is stratification,if the paint is too dense, you can add a little water and stir well, the bottom layer should be more dilute

Available Time And Hard Drying Time

When the environmental temperature is 20℃,the surface dry time is 6 hours,the hard drying time is 12 hours,The environment temperature is low, humidity is big, ventilation is poor, the available time and dry solid time are long, on the contrary, it is shorter.

Amount Quantity:2.6kg/m2


Construction operation

Coating the layer with the rolling brush or brush, in accordance with the bottom - lower - non-woven cloth(glass fiber cloth)-middle-upper layer, If the the lower needed to be added cloth,lower layer,non-woven cloth layer and the middle layer construction should be continuous. The intervals between the layers should be based on the dry solid of the previous coating. According to the actual requirements of the project,it can be made three layers or four layers,non-woven cloth(glass fiber cloth)and color can be added or not.


1.Application temperature below 0℃ or outside application in rains are not allowed.

2.Once the packaging is opened, it is best to use up at once, and the unused paint should be tightly sealed.

3.The coating is evenly as soon as possible,not partial deposition, each layer must be coated according to the prescribed amount of material, the coating layer can not be too thick or too thin, if the thickness of waterproof layer is not enough, you can add a layer.

4.The protective layer should be done when finishing the waterproof layer so as to avoid the waterproof layer
