– Excellent in appearance and excellent in weather resistance, durability, adhesion, impact resistance, etc. .

–  Reduces fatigue and improves performance by absorbing and weakening shock.

–  It is resistant to cracks and vibrations and has no deformation.

–  Easy maintenance and low maintenance cost.

­  Apartment, rooftop waterproofing of buildings

–  Waterproofing of underground concrete structures

–  For general offices, hospitals, schools, libraries, etc.

­ Use masks, gloves, or other protector during the application.

­ Store the remaining materials quite sealed after use.

­ Do not exposure to the moisture.

­ In case of ingestion or skin contact, administrate first aid according to notice on container or Material Safety Data Sheet(MSDS), and see the doctor immediately.

This Sheet is a kind of standard of operations, so if there a specification for detail work and there are some difference in the two documents, it’s nice to work according to the specification.

PREPARATION

and it make poor adhesion with polyurethane and surface. So it must be removed for

strong film and excellent adhesion.

2)       Cure the concreted surface sufficiently to remove the alkali of the surface and keep the

moisture content within 8% max.

3)       Clean the surface with acid , sandblast or grinding if you need.

4)   It should be cured completely when the appropriate primer or equivalent material was applied.

5)   Remove dust, sand, moisture and oil on the surface.

6)   In case that the surface to be applied is damp, dry fully and apply.

WORK

­ Check the cleaned surface.

­ If there are some water it must be dried and must be not dusty.

­ Then apply to cleaned surface with proper primer, seretite undercoat

­ Apply with the WP-300 after curing the primer. It may be one to twelve hours after seretite coat coating.

­ See the DIRECTIONS FOR USE of seretite undercoat for the details.

2. Direction for WP-300

­ Check the curing of seretite undercoat coating and then apply the WP-300.

­ Mix well part A, B and C by correct mixing ration with electric agitator.

­ Must mix well part A, B and C to scrape up the product on the wall of package cans. Otherwise you might have the failure curing film.

­ After mixing well sufficiently, apply to surface with the WP-300 with rake or roller.

­ If you need more than 3㎜ thickness, apply within 3㎜ per one time until to get aiming

thickness.

­ When the temperature is higher than 28℃, you might as don’t use as possible. But in that case unavoidable applying, must apply 2 or 3 times for intermediate coating and apply it after 5 p.m.

3. Direction for Polyurethane TOP COAT

­ Check the curing of intermediate coating and then apply the TOP COAT.

­ Repair the intermediate if there are some problems as curing problems or coming undone from the floor.

­ Mix well the TOP COAT part A and part B.

­ You’d need electric agitator because the viscosity of top coat is very low.

­ Coat the surface with mixed well TOP COAT with paint roller, sprayer or other

instruments.

­ It could be used thinner when it need to adjust the fluidity for easy control.

­ Do not use the alcohols as thinner, the alcohols react with the TOP COAT and became poor film.

­ If you use sprayer, clean well the hose and other equipment of sprayer after the operations to

prevent curing the TOP COAT in the equipment.

­ Keep prevent passage in 24~72 hours after applying and then permit when it fully cured.

­ See the DIRECTIONS FOR USE of TOP COAT for the details

2)       Must use suitable thinner, otherwise you must get failure coating film.

3)       Products of this type can be expected to be eye and skin irritants and have the potential to cause sensitization or other allergic responses.

4)       Appropriate precautions should be taken to avoid eye and skin contact and to avoid inhalation of the aerosols or vapors.

5)       Consult the relevant Material Safety Data Sheet for appropriate handling procedures and protective equipment prior to using this or any other material referred to in this bulletin.

6)       See Material Safety Data Sheet for emergency and first aid procedures.

7)       Must not use this product for other purposes except for it’s own use.

8)       Keep adequate ventilation during the application.

9)       Store it indoor and cool place and keep away from ignition.

10)    Once opened, containers should be resealed immediately after removal of the product.

11)    Keep away from children during coating and storing.
