Main technical parameters

Construction process

1、 Construction preparation

Surface treatment of substrate

-Ensure that the surface of the substrate (such as concrete, cement mortar surface) is flat, solid, and free of defects such as looseness, hollowing, sanding, and cracks. If there are cracks, they need to be filled and leveled with repair materials first.

-Remove dust, oil stains, accumulated water and other debris from the surface of the substrate, and keep it dry (recommended moisture content ≤ 8%).

-The internal and external corners need to be made into rounded corners (with a radius of about 50mm) or obtuse corners, and the nodes such as the pipe root and floor drain need to be reinforced.

Inspection of waterproof coating

-Check if the single component polyurethane waterproof coating is within its shelf life; Due to the possibility of precipitation during long-term storage of waterproof coatings, they can be stirred before use to evenly distribute the sediment (without adding water or other diluents). After stirring, the product performance will not be affected.

2、 Construction steps

Apply the first coat of waterproof coating

-Apply evenly with a brush or roller onto the prepared substrate, with a thickness controlled between 0.8-1mm, ensuring no missed brushing or accumulation.

-Wait for the first coat of waterproof coating to dry (usually 2-4 hours, depending on the ambient temperature and humidity, subject to non stick to hands).

Apply a second coat of waterproof coating

-The direction of the second coating is perpendicular to the first coating (cross coating) to ensure even coverage of the coating, and the thickness is also controlled within 0.8-1mm.

If you need to increase the waterproof thickness, you can apply the third coat after the second coat is dry. The method is the same as above, and the total thickness is recommended to be ≥ 1.5mm. The general construction thickness requirement is 2mm (according to the design requirements).

3. Maintenance and acceptance

After the final coating is completed, it should be naturally cured for more than 72 hours (the curing time should be extended when the temperature is below 10 ℃), and during this period, avoid exposure to rain, water or external damage.

After curing, check whether the coating is flat, without bubbles or cracks. Only after passing the inspection can subsequent construction (such as backfilling, tiling, etc.) be carried out.

Packing specifications

25KG/Bucket

Storage

This product sealed storage, recommended storage temperature of 5~25℃ cool dry place; The storage period is 9 months.

Precautions

Construction environment

-The temperature should be between 5 ℃ and 35 ℃, and construction should be avoided on rainy days, windy days, or when the substrate surface is damp.

-During construction, it is necessary to wear protective masks and gloves, stay away from sources of fire, and work in a well ventilated area.

Storage

-Sealed storage in a cool and dry place, away from sources of fire and heat, avoid direct sunlight, and use within the shelf life.

Other

-Before the coating is cured, pedestrians and vehicles are prohibited from crushing it to avoid sharp objects scratching the coating.

-If it needs to be used in combination with other materials (such as rolls, primers), compatibility needs to be confirmed and a small-scale test needs to be conducted first.

By following the above method of construction, the waterproof effect of the polyurethane waterproof coating can be fully utilized, effectively resisting water infiltration.
