BK-177EP 2K epoxy resin binder for paving joint mortar

Epoxy resin paving jointing mortar consisting of components A + B, is mixed with kiln-dried quartz sand and is ideally suited for medium to large areas requiring jointing.

Product data

• High-quality paved areas, NO weed growth through the joints, thus low maintenance effort afterwards
• Fast and clean jointing, also water-emulsifiable and workable even in drizzle, as well as using the "slurry method"
• Suitable for sweepers, allowing for easy, mechanical and time-saving cleaning
• Chemical-resistant to aggressive cleaning agents

Coverage

• 0.5kg epoxy resin jointing mortar is sufficient for 5kg quartz sand
• 1kg epoxy resin jointing mortar is sufficient for 10kg quartz sand
• 2kg epoxy resin jointing mortar is sufficient for 20kg quartz sand

Technical data

• Mixing ratio (by weight): 100 parts resin/100 parts hardener
• Viscosity: Medium viscosity
• Pot life at 20°C: 60min (100g)
• Walkable at 20°C: 6h (temperature dependent)
• Driveable at 20°C: 7d (temperature dependent)
• Application temperature: 10°C-25°C

Application

1. Preparation
Clean the joints to a depth of at least 30 mm (2/3 of the stone height in traffic areas) as well as the area to be jointed free of residues (minimum joint width 5 mm). Adjacent areas that are not to be jointed are taped off.
 
2. Pre-wetting
Pre-wet the area sufficiently. Avoid puddles or standing water. In principle, use clean and cold tap water when pre-wetting, mixing and cleaning.
 
3. Mixing
Place the mineral filler in a suitable mixing bucket and slowly and completely add the separately mixed epoxy resin into the center of a depression. Start the stirring process with a mixing time of approx. 2-4 min. Depending on the desired consistency, in the final step, add at most the same amount of water (relative to the epoxy resin) and mix into a homogeneous mass, e.g., for 1.0 kg of epoxy resin, add max. 1.0 L of water.
 
4. Application
Then pour the paving jointing mortar onto the area in spots and carefully distribute it with a rubber float and work it intensively into the joints. Then sweep the area with a moistened coconut/hair broom and free it from mortar residues. It is recommended to moisten/clean the broom frequently with water. Then thoroughly spray the paved area with a fine water jet and sweep it again with a wet coconut/hair broom. Moisture protection is not necessary in drizzle. In case of continuous or heavy rain, the freshly jointed area must be protected from rain for 7 - 9 h (depending on the temperature). The moisture protection must not be placed directly on the area so that air can circulate.
