Product Details

Joaboa Tech Coating Series

NRB Non-curing Rubber Bituminous Waterproofing Coating is made of rubber, bitumen, and additives, which always remain viscous during application. NRB bituminous paint for foundation is supposed to be heated in site to flowing state, then brushed or sprayed on the substrate to form a waterproof layer with strong cohesion, excellent creep property, and self-healing.

NRB bituminous paint for concrete foundation is both a waterproof layer and a bonding layer as well.

NRB Bitumen Waterproofing Paint for Concrete is Joaboa Tech's great contribution to the waterproofing industry, as well as am important part of Joaboa Tech Zero Defect Waterproof System, which is Top 1 High End Waterproof System from Chinese mainland, which has enjoyed great reputation in the international and domestic market.

※ Material Features

1. Non-curable

The solidified substance content is more than 99%, almost no volatile matter, and it can always maintain the original state after construction.

2. Excellent Bonding Strength

After construction, NRB bituminous foundation coating always keeps viscoelastic, and the bonding effect lasts for a long time.

3. Persistent Adhesive Performance

The durable viscoelastic state ensures the durable sealing of the material to the base.

4. Dual Functions

NRB bituminous waterproofing paint is not only a waterproof layer, but also can act as an excellent bonding layer.

5. Strong Self-healing Performance

Even if the waterproof layer is damaged during construction, NRB waterproofing bituminous paint black can repair itself to maintain a complete waterproof layer.

6. High Elongation

Good flexibility, high elongation, adaptable to base deformation.

7. Wide Applicability

NRB bituminous paint waterproofing can be constructed at normal temperature or below zero.

※ Scope of Application

NRB Bituminous Liquid Waterproofing is an excellent waterproof material, suitable for building basement, roof and other waterproof parts. NRB asphalt waterproofing paint can be used as the bonding material of modified asphalt waterproof coils, and can also be used as the auxiliary material for sealing of self-adhesive waterproofing membranes.

NRB Coating can also be used as a bonding layer for other waterproof materials.

※ Construction Points

1. The heating temperature and the coating temperature of this material are high. The construction personnel should wear the necessary labor protectiontools (such as gloves) to avoid high temperature burning.

2. The material is a creep solid at regular temperature, so it must have good application performance at a suitable temperature. lf the unfinished coating's temperature decreases during application, it shall be reheated.

3. When reinforcement material is needed, it is better to pave beIore tnebottom coating cools. The surface coating can be brushed immediately after paving.

4. When the coating is only used as waterproofing layer alone, non -woven fabric or asphalt felt should be paved as an isolated layer after brushing coating. Then protective layer can be carried out.

5. The heating limit temperature is 200℃ and the heating cannot be sustained for more than 30 min.

※ Construction Methods

NRB Non Curing Rubber Bitumen Waterproofing Coating can use construction methods as below: Hot Application (or called hot applied or hot-applied).

HOT APPLICATION is composite of rubber asphalt waterproof coating and self-adhesive membrane which is closely bonded with the base layer to form a "skin-type" waterproof system. It is an organic whole with complementary advantages, which can adapt to the deformation and self-healing performance of the base, effectively prevent water channeling and reduce leakage hazards.

Substrate Requirements

1) The firmness and strength of the base layer should meet the design requirements.

2) The surface of the base layer should be clean and smooth, and there should be no quality defects such as powdering, sanding, peeling, voids and pits.

3) Remove sundries, greasy dirt, sand, etc. on the surface of the base layer, and the cleaning work must be carried out at any time during the construction.

4) If there is clear water on the base layer, it needs to be cleaned before construction. If the base surface is relatively damp, it needs to be dried with a blower.

※ Techinical Data Sheet of NRB Bitumen Coating

Joaboa Tech is the main editor of China Industrial Standard for Non-curable Rubber Modified Asphalt Coating for Waterproofing, JC/T 2428-2017.

※ Storage and Transport

1. Stored in a cool and dry place, away from direct sunlight, moisture and fire.

2. The storage period is six months. After the expiration, it shall be tested again. NRB waterproofing bituminous paint can be used again after passing the test.

3. Upside-down stacking, stacking no more than three layers.

4. Under normal storage and transportation conditions, the storage period shall be at least 12 months from the date of production.

※ Packing Method

Professional loading method with wooden pallets to ensure the safety of NRB Non Curable Rubber Bitumen Waterproofing Paint during export.

※ Market Share

Joaboa Tech, Inventor and Representative Brand of Chinese Self-adhesive Waterproof Membrane, whose market share has ranked as Top 1 in Chinese domestic market for over 10 years, widely used in Viet Nam, Cambodia, India, etc. as well.
