APPLICATION:

Coating system:

01 layer of BestPrimer PU715: 0.15-0.30 kg/m2/layer (Tensile strength of surface ≤ 1.5 MPa)
02 coating layer of BestCoat PU714: 0.15-0.25 kg/m2/layer (depend on surface condition).

Substrate requirement:

Concrete surface: Compressive strength: ≥ 20 MPa, tensile strength: ≥ 1.5 MPa. Surface should be flat, solid, steady, dry (moisture content ≤ 4%). Impurities, broken pieces, dust should be cleaned as required.
Metal surface: should be free from rust, oil or impurities such as dust, water...

Mixing:

Before applying, two components A and B should be properly mixed under the right ratio by slowly stirring (at speed of 300 ÷ 500 rpm).
Minimum mixing duration should not be less than 03 minutes and can be longer until reaching the required homogeneity.

Application:

Apply by roller, brush or air-less sprayer.
Notes: Do not use mixtures over time to apply and get hardening.

Cleaning

Safety:

Two components are dangerous, flammable, and allergic when contacting directly to the skin.
If gushing out eyes, noses, and mouth, must be washed with fresh water before taking to the nearest hospital.
Unconditional, NO place product or constructing area contact directly to flame or heat genetic source.
Pouring residual products in regulation place of local government.

SURFACE PREPARATION:

Concrete surfaces:
Compressive strength ≥ 20 MPa, tensile strength ≥ 1.5 MPa. The surface must be level, sound, and dry (maximum moisture content 4%). All contaminants, debris, and dust must be properly removed.
Metal surfaces:
Must be free from rust, oil, grease, and other contaminants such as dust and water.

MIXING:

Before application, components A and B must be thoroughly mixed in the correct ratio using a low-speed mixer (300–500 rpm). Mixing time should be at least 3 minutes or longer until a homogeneous mixture is achieved.

APPLICATION:

Can be applied using a brush, short-nap roller, or high-pressure spray equipment.
Note: Do not use material that has exceeded its pot life or has started to cure.

CLEANING:

Use BestThinner SC-03 to clean tools immediately after application and before the material begins to cure.

SAFETY:

Both components are classified as hazardous and flammable. Keep away from heat sources, sparks, and open flames during application and storage. The product may cause allergic reactions on sensitive skin upon prolonged contact. Protective gloves, masks, and safety goggles are recommended during application.
In case of contact with eyes, nose, mouth, etc., rinse immediately with plenty of clean water and seek medical attention at the nearest healthcare facility. Dispose of excess material in accordance with local regulations.
