BestFloor AC350 uses in the following cases: 

• Repair and reconstruct the floor’s surface which is damaged by erosion, collision, or mechanical abrasion. 
• Renew flatness of floor before applying tile PVC, carpet, or coat other specific coat.
• Use in areas where the floor is always stand by medium and light loading such as factory, car park, swimming pool bottom, water tank,…
  

• Components are accurately quantified and are available at the factory, so they are easy to use, minimizing risks during construction. 
• Good flexibility, and high self-leveling ability, make it easy to construct.
• Limit shrinkage, and surface cracks during curing. 
• Fast and high development intensity, quick to put the works into use.
• Enhance anti-wear, anti-oil, anti-contamination, anti-moisture, and waterproof for the substrate surface, and floor. 
• Increase the aesthetic value of the work.
• Environmentally friendly, non-toxic, and does not contain Cl that corrodes reinforcement.
• Suitable for climate conditions in Vietnam

Physical properties ( After 28 days):

Compressive strength (*) : ≥ 35 MPa

Flexural strength(*) : ≥ 10 Mpa

(*): Standard: ASTM C349, ASTM C348 with sample 4x4x16 cm, do not soak into water.

(**):Standard: ASTM D7234-05.

Surface preparation:

• The concrete surface and floor must have a minimum compressive strength of 20 MPa and a minimum tensile strength of 1.5 MPa and must be suitable for the actual use load. Adhesive plaques or weak concrete surfaces must be completely removed by mechanical means. Oil and grease stains must be thoroughly and properly cleaned. Smooth surfaces must be properly roughened before application.
  

Mixing:

• Pour part A into a fresh tank and then pour slowly part B into the tank with the right ratio while the paddle is stirring continuously (speed about 400÷ 500 rounds/ min) within the time about 05 mins until a lump is free and the homogeneous is obtained.
• Keep the mixture for about 03 ÷ 05 minutes, then mix again before applying.
  

Application:

• Apply the BestFloor AC350 screed to the surface when the BestBond EP759 bonding layer turns transparent but is still wet. Pour continuously in beds with a width of 200 ÷ 300 mm, using a serrated rake to spread the BestFloor AC350 mixture evenly on the surface according to the required thickness with a maximum thickness of 5 mm/layer.
• Use spike rollers to aid in leveling and air release of the layer of material.

Notice:  

• The allowable application time of the material is about 30 minutes from the time of mixing. In case of not using the BestBond EP759 bonding layer, the concrete surface must be saturated with water (no longer able to absorb water) before applying BestFloor AC350 to avoid air leakage causing perforation of the material surface.  
  

Curing:

• After 72h from the time of application, the substrate can be cured by BestCure AC015 or BestCure SS015.
  

Health and safety:

• BestFloor AC350 is alkaline, so it can cause allergies to sensitive skin with long exposure. Gloves, masks, and safety glasses should be worn when working with the product.
• If the product gets into eyes, nose, or mouth, should immediately wash with clean water several times before going to the nearest medical facility for timely and proper treatment.
