SURFACE PREPARATION
- Substrates to be applied with Lemax 201 must be clean and free from laitance, protrusions, loose particle, dirt, oil and grease.
- Sharp edges must be flattened and uneven surfaces must be leveled or repaired with a mortar screed by using Lemax 600.
- Clean and proper repaired surface must be thoroughly saturated with water prior to application of Lemax Primer.
- Be caution: No standing water or excessive water shall be remained on the substrate that to be applied with Lemax 201.

MIXING

Lemax 201 is supplied in 2 components, to generate a consistent slurry, pour the liquid component into a pail following by adding in the powder component gradually to the liquid. In the meantime, use a stirrer to stir the mixture until the mixture is free from lumps. Take note of the consistency of the slurry. The consistency of the slurry can be altered by reducing or adding in powder component.

APPLICATION

- Apply Lemax 201 with a stiff brush or spray onto the prepared surface with at least two coats. Interval of each coat should be 1-2 hours minimum. To avoid pin holes and ensure full coverage, apply each brush coat at different direction.
- For large space, spray is recommended by using a worm-gear type of spray equipment.
- For best result, apply Lemax 201 under shaded shelter to prevent rapid drying of the coating.
