Product Description

DM189 100% silicone roof coating

DM189, a professional grade 100% silicone roof coating, is a high performance, solvent-free, high-solids, water-free and asphalt-free building material, and also a non-slump waterproof sealant for construction. Meets waterproof requirements and is a sealant for horizontal surfaces. After being completely cured, the sealant will not penetrate water, and the maximum cracks of the bridge are 5 mm, and can resist the natural groundwater that corrodes the concrete.

Advantages
1. Based on advanced technology, DM189 combines reliable crack bridging and waterproof performance
2. No solvent, no water and no asphalt. DM189 has unparalleled ease of handling to replace asphalt emulsion.
3. Very good weatherproof advantage, service time is 20 years+.

Product Applications

Applications

1. Building waterproof: used to provide long-term protection for structural elements in contact with the soil, such
as basements, buildings without underground layers, foundations, floors, connectors, pipe casings from ground moisture, retained water.

2. Horizontal surface: DM189 liquid is used to seal larger horizontal surfaces, such as foundations, floors, as a
moisture-proof sealing material for commercial areas, and on balconies and terraces combined with screed and ceramic tiles. It is also suitable for filling settlement joints and expansion joints in commercial and industrial fields. 3. Precast concrete parts:
DM189 has high water-permeable concrete structural members with external stripe sealing, do not press water and ground moisture.
4. Substrate: Masonry, porous concrete/block, lime sandstone/block, precast concrete parts, concrete and watertight concrete. It is a one-component moisture-curing elastic sealant. 5. DM189 liquid can be directly coated on slightly damp substrate without primer. Avoid standing water.

Use instruction:

Product application range: Used as a waterproof coating for flat roofs and sloping roofs, including new roofs and roof repairs. Construction method:Construction shall be carried out in the following order: 1. Clean the roof: the roof must be cleaned before construction, and there should be no oil stains, deposited sand, residual paint, etc. 2. Open the paint cover, the paint will settle during storage. Use a stirring tool to stir the paint evenly before use. 3. Apply the paint directly to the roof by spraying with an airless high-pressure sprayer or brushing. 4. Strive for uniform coating, with a dry film thickness of at least 0.5mm. Precautions 1. For some rubber and plastic materials may have poor adhesion, so pre-testing is required before construction. 2. Do not construct in rainy weather, and do not allow water to accumulate before the construction of the flat slope roof. Avoid rain water within 4 hours after coating application. The surface drying time of the coating is about 50 minutes, and the surface drying speed will be faster under high temperature conditions and slower in winter. Pay attention to use up before the surface is dry after opening. 3. After the coating is applied, there must be an interval of more than 8 hours before walking on it. 4. The construction tools must be cleaned before the glue is cured. Diesel oil can be used to clean the tools. Product specifications: 18L/barrel. Storage period: 12 months Storage and transportation requirements: Store in a cool and dry place, away from fire.
