TECHNICAL SPECIFICATIONS

Application information:

• Ambient application temperature: minimum +10 °C / maximum +35 °C.

• Working time: ~ 45 minutes from mixing (at 27°C).

• Application thickness: maximum 1 mm per coat.

Technical properties:

Adhesion strength: ≥ 1.0 MPa (at 28 days on a prepared concrete surface).

• The surface to be waterproofed must be clean, sound, and free from oil, grease, dust, moss, excess cement, and other contaminants, etc.

• Surface defects (cracks, voids, etc.) must be repaired and patched using suitable specialized repair products from Bestmix (contact technical support for advice).

• Saturate the entire surface with clean water but do not allow water to pond on the surface.

APPLICATION PROCEDURE

Mixing:

- Pour Component A (liquid) into a clean mixing bucket with a minimum capacity of 15 L, then gradually add Component B (powder) while mixing with a low-speed paddle mixer (300-400 rpm) until a homogeneous, air-bubble-free mixture is obtained; be sure to scrape down any material adhering to the sides of the bucket into the mixture to prevent it from drying out.

- Mixing time: minimum 5 minutes, or longer until a homogeneous mixture is obtained.

Application:

- BestSeal AC402 Lite can be applied with a short-bristle brush or a suitable spraying machine.

- To ensure waterproofing performance, BestSeal AC402 Lite must be applied in at least 2 coats, with each subsequent coat applied perpendicular to the previous one after it has dried. The waiting time between the two coats is 1-2 hours depending on weather, temperature, and ventilation conditions.

Note:

- Avoid mixing the product in partial portions; use a weighing scale to ensure the mixing ratio complies with the manufacturer's recommendations. Mechanical mixing is recommended.

- When used as a sealing, repair, or patching compound for surface defects, the mixing ratio is A/B = (0.75 - 0.80)/4.0 (by weight).

- Saturate the application surface with clean water and remove excess water before application.

- If applying under sunny and windy conditions, the moisture-retention curing requirements must be strictly followed, as with other cement-based products, to prevent rapid water loss that would damage the quality of the waterproofing surface.

- Do not use any mixture that has exceeded its working time and has begun to set.

- Do not add any other material to BestSeal AC402 Lite, including clean water.
