Product details

This waterproof repair mortar boasts excellent waterproof performance, which can effectively block water penetration. It features strong adhesion, forming a firm bond with the base layer to ensure the repair layer does not easily fall off. It has high durability, resists aging even after long-term use, and delivers long-lasting waterproof effects. It is cost-effective, offering high value for money and reducing long-term maintenance costs.

Key parameters: Water retention rate 99.8%; Impermeability pressure (7d) 1.1Mpa; 28d compressive strength 9.9Mpa; 28d shrinkage rate 0.13%; Bond strength (7d) 1.2Mpa; Frost resistance: no cracking or spalling; Water absorption rate 3.1%; Radioactivity: 0.1IRa, 0.3Ir

Applicable Scenarios

Suitable for solving wall leakage problems that are difficult to address with traditional grouting processes. It can be used on both water-facing and back-facing surfaces, and is resistant to long-term immersion.

It can also be used for waterproofing wall bodies and floors, as well as areas with cracks, leakage from traditional mortar, or indentations.

Compatible with various base materials including concrete, brick and stone, it can address leakage issues in complex scenarios such as wall surfaces, basements, and water tanks.

Professional solution for renovation scenarios

Leakage problems

Simple construction process

High durability

Ready for handover after sanding

The surface shall be flat, clean, and free of oil stains, floating dust, release agents, etc.; otherwise, it will affect the adhesion of the material to the wall surface;

Work type selection: It is recommended that construction be carried out by putty workers or waterproofing workers;

Construction Step 1:Dilute the curing accelerator with water at a 50% ratio, spray it evenly onto the base layer twice without pressure, and trowel on the waterproof repair mortar once it is dry;

Construction Step 2:Mixing ratio for waterproof repair mortar: Powder Component A : Liquid Component B : Water = 4:1:1.3-1.5 (The water dosage can be adjusted within a 10% range due to variations in weather and temperature). Apply by trowel coating, with a recommended thickness of 0.5-0.8mm per coat; the second coat can only be applied after the previous coat is fully cured (approximately 4-6 hours). Thickness control: Note that thick application is not allowed; the thickness of each trowel coat must not exceed 1mm (otherwise, there is a risk of cracking). If the base layer surface has large flatness deviations, first level it with waterproof mortar before troweling on the waterproof repair mortar;

Leveling and Finishing:After the mortar is applied to the wall, leveling work is required. An h-type scraper can be used to level the wall from bottom to top, collecting the scraped-off material; fill indentations with additional material, and aim to complete leveling in a single pass. Whether surface finishing is required depends on the specific construction requirements, and it is recommended to perform finishing when the mortar is in a semi-dry state;

Base layer moisture condition:There shall be no standing water on the surface during construction;

Storage conditions:Store in a dry place to prevent the material from getting damp.

Usage reference:For a single trowel coat with a thickness of approximately 0.5mm, the material consumption is about 0.6-0.8kg/m2

One set of materials (8kg of dry powder Component A + 2kg of liquid Component B = 10kg) can cover approximately 12.5-17m2 (for two trowel coats)
