Self-leveling Underlayment

- Grout Wel 808 is a one-component, cement-based pre-mixed mortar that, after mixing with water, will produce a high-flow, self-levelling grout. Used for surfaces that need to be leveled or refurbished before applying other finishing works for concrete floors and floors in places with medium and light loads such as: factory floor, parking lot, lake bottom swimming pool, water tank epoxy floor, vinyl, tile, wooden floor, ...

SURFACE PREPARATION:
- Before applying, clean the surface free of grease and impurities.
- The absorbent surface needs to be saturated but not stagnant. Use pressure water to wash away impurities and dirt.
- Adhesive plaques or weak concrete surfaces need to be completely chiseled away by mechanical means.
AGITATION:
- Put Grout Wel80 slowly into the tank of clean water that has been pre-quantified with a mixing ratio of 5 liters of clean water for 25 kg of powder. Continuously stir with the mixer at maximum speed of 500 rpm for about 5 minutes until the mixture is no longer lumpy and homogeneous as required. Leave the mixture for 3 minutes and then mix again before applying.
CONSTRUCTION:
- Pour the mixed grout onto the cleaned floor and the expansion joints have been securely covered;
- If the floor is large, after grouting should be cut to create a maximum expansion joint of 4m x 4m.
- Use a serrated brush (the tooth root height depends on the desired mortar thickness) to spread evenly over the surface;
- Then use a roller to degas the surface, self-leveling mortar will fill in the convex, concave, and self-leveling positions to create a smooth, moisture-proof surface.
- After 24 hours, the self-leveling mortar layer dries and hardens, the next steps can be applied to finish the interior.
NOTE:
- When the connecting primer is dry (no longer sticky to hands), it is necessary to roll another layer before applying Wel808 self-leveling mortar.
- Do not use materials that have expired construction time.
- Cleaning: Clean tools with clean water immediately after use and before the mixture begins to harden.
