BestFloor PC302
Self-leveling mortar, Polymer-cement based, one component
Advantages:
Single-component, precisely pre-batched and homogenized at the factory, so it is easy to use (just mix with water at the specified ratio) and minimizes risks during application.
Good flowability and high self-leveling ability, with no segregation or layer separation.
No volume shrinkage and no surface cracking during curing.
Fast, high strength development, shortening curing time and quickly putting the structure into use.
Enhances abrasion, oil, stain, moisture and water resistance of the floor surface.
Increases the aesthetic value of the structure.
Non-toxic, environmentally friendly, contains no chloride (Cl) that corrodes reinforcement.
Suitable for Vietnam's climate conditions.

Applications
BestFloor PC302 is used in the following cases:
Repairing and restructuring floor surfaces damaged by aggressive attack, impact or mechanical abrasion, etc. during use.
Re-leveling floor surfaces before laying PVC vinyl tiles, carpet or other specialized coverings on top.
For concrete floors in areas with light to medium loads such as factory floors, laboratories, cleanrooms, hospitals, parking lots, swimming pool bottoms, water tanks, etc.

Application instruction
Surface preparation:
The substrate must reach a minimum compressive strength of 20 MPa. Poorly bonded patches or weak concrete surfaces must be completely chipped away by mechanical means. Impurities, oil, grease and dust, etc. must be thoroughly cleaned by the proper method.
Mixing:
Slowly add BestFloor PC302 into a pre-measured container of clean water (optimal mixing water ratio is 12% by powder weight — 03 liters of clean water per 25 kg) and stir continuously with an electric (or pneumatic) mixer at a maximum speed of 400 rpm for about 05 minutes until the mixture is lump-free and homogeneous as required.
Let the mixture stand for 01 minute, then re-mix before application.
Application:
Apply a BestBond EP759 bonding coat (see the product's instructions) onto the surface prepared as described above.
When the BestBond EP759 bonding coat turns transparent but is still wet, apply the BestFloor PC302 mortar layer on top. Pour continuously in strips 200 ÷ 300 mm wide, and use a notched trowel to spread the BestFloor PC302 mixture evenly to the required thickness, maximum 5 mm/layer.
Use a spiked roller to assist leveling and de-aerating the material layer.
Notes:
Maximum working time is 30 minutes from mixing. Mix with the correct water ratio as specified.
Use a mixer at a suitable speed; do not mix by hand, to ensure the required homogeneity.
If the BestBond EP759 bonding coat is not used, the concrete surface must be saturated with water (no longer absorbing water) before applying BestFloor PC302 to avoid de-aeration that pinholes the material surface.
To achieve the highest mechanical properties, the product after application must be cured according to the proper procedure, like other cement-based products. Minimize evaporative water loss using available materials such as water-soaked hessian, plastic sheeting, or curing compounds BestCure AC015 or BestCure SS015.
Cleaning:
Clean tools with water after application and before the material cures.
Safety guidance:
BestFloor PC302 may cause irritation to sensitive skin on prolonged contact. Wear a mask, gloves and safety goggles when using the product.
If splashed into the eyes, nose or mouth, rinse immediately with plenty of clean water several times before going to the nearest medical facility for timely and proper treatment.
