• No shrinkage, no surface cracking during curing.

• Fast and high development intensity, quickly put the project into use.

• Good bond to all cementitious materials even in the case of moisture.

SURFACE CLEANING:
- Before construction, it is necessary to clean concrete or steel surfaces, free from grease and impurities. Install the formwork firmly, make sure there is no leakage.
- 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.

PROCEED MIXING:
- Put Grout Wel 808 slowly into a tank of clean water that has been pre-quantified with a mixing ratio of 4.5 liters of clean water for 25 kg of powder.
- Continuously stir with a mixer at a 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, then mix again before application.

CONSTRUCTION INSTRUCTIONS:
- 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 (root height depends on the desired mortar thickness) to spread evenly on the surface. Then use a roller to degas the surface, the self-leveling mortar will fill in the convex, concave, and self-leveling positions to create a smooth surface.
- After 24 hours, the self-leveling mortar layer dries and hardens, the next steps can be applied to finish the interior.

NOTES WHEN USING:
- When the bonding primer is dry (no longer sticky to hands), it is necessary to roll another layer before applying Wel 808 self-leveling mortar.
- Do not use materials that have expired construction time.
- Cleaning: Use clean water to clean tools immediately after use and before the mixture begins to harden.

STORAGE AND STORAGE:
- Minimum 12 months in original unopened packaging and stored in cool dry conditions below 30°C.

SAFE:
- May cause allergic reactions to sensitive skin with prolonged contact.
- Should wear gloves, masks, safety glasses when working with the product.
