Product Description

E***8A High-Polymer Modified Cement Elastic Waterproof Coating

About products
KS***8A high-polymer modified cement elastic waterproofing coating (JS) is made up by acrylate emulsion, cement and inorganic materials, typeⅠ and type Ⅱare available according to their different performance.

Features
Environmental protection, non-toxic, harmless; safe.
High bonding strength for many types of mortar substrate.
Can be applied on wet and dry substrate directly
Good performance of flexibilty,waterproof and durability
Can be applied on verdical,slope and top surface directly,no flow,easy to use
Good weatherability,it can be applied on the outdoor roof without special protective layer(normal protective layer is needed)

Scope of application
Type Ⅰ is suitable for dry and non long-term immersion environment, e.g. Roof and so on.
Type Ⅱ is suitable for long-term immersion environment, e.g. washroom and underground construction.

施工要点Key Point for construction
Substrate Treatment
The substrate  must be smooth,firm,clean,without obvious water trace ,fix the crack,the interal and external corner should be made into round corner.
Clean the old concrete surface with strong detergent,then further clean with water,wait until it is completely dry before application.

ratio
TypeⅠ liquid：powder：water = 1：1.2:0.6 (weight ratio)
TypeⅡ liquid：powder：water = 1：1.5:0.8 (weight ratio)
Use mechanical mixer to stir them evenly  before application.

ratio
TypeⅠ liquid：powder = 1：1.2 (weight ratio)
TypeⅡ liquid：powder = 1：1.5 (weight ratio)
Add the powder into liquid slowly and use mechanical mixer (******0 rotations per min) to stir them evenly in **5min.


Operation points
Multi-layer application by roller and scraper. The coatings should not too thick or it will dry too long.
Apply the  protective layer  after the coating is dry (**7days normal temperature condition).


Announcements
Constructing below 5℃ or in the sand are not allow.
If it is wet or ventilation is poor, the coating will dry slowly, otherwise it will dry quickly.


Appearance
The liquid is Milky white liquid glue, and the powder has two colors, white and black.


Packing specifications
TypeⅠ*0g liquid**4g powder 
TypeⅡ *0g liquid**0g powder


Reference dosage
When the film is 1.0 mm, the dosage is about:
                                    TypeⅠ1.9g/m2
TypeⅡ1.*5g/m2
(the dosage is the powder and the liquid’s gross)


Storage and Transport
The storage temperature should be below 5℃
Avoid raining, insolation, squeezing, colliding.
Storage period: one year
