EasyMix Water-Proofing Bond Coat EPBB880#

EasyMix Water-Proofing Bond Coat EPBB880#

Product Description

EasyMix Water-Proofing Bond Coat EPBB880# is a two-parts polymer-modified formulation composed of high-performance emulsion, cement, graded aggregates, and functional additives. It exhibits low shrinkage, a coarse bonding surface, exceptional waterproofing, and high adhesion strength.

Product usage

1.Interior/exterior concrete, masonry, and panel wall substrate preparation and waterproofing.
2.Permanent waterproofing layers in kitchens, bathrooms, bedrooms, and balconies.
3.Permanent waterproofing for basements, landscape water features, and reservoirs.
4.Bonding primer for low-absorption substrates (e.g., glazed tiles, stone slabs).
5.Resolving hollowing or delamination in concrete rendering and tile installation.

Advantages

1.Dual-functional: Integrates waterproofing and substrate treatment in a single application.
2.Flexible crack resistance with excellent waterproofing and water resistance.
3.Superior workability; coarse finished surface enhances mechanical adhesion.
4.High weather resistance and environmentally friendly

Application

1，Substrate Surface Preparation

1.Ensure the substrate is structurally sound, even, free from hollowing, and that the surface is clean, free from oil,dust, and loose materials.
2.Prior to application, clean the substrate thoroughly and apply the Two-Component Waterproof Bonding Primer atthe appropriate moisture level.
3.Pre-application of the primer EPP308 to seal the substrate capillaries can significantly enhance the final result.
4.Pre-repair any substrate defects; it is recommended to use Easibond repair mortar. Remove any protrusions bychipping.
5.Concrete and masonry walls must have achieved proper curing period and strength before application.

Material mixing

1.Pour Component B (liquid) into a suitable container. Slowly add Component A (powder) at a powder-to-liquidratio of 2.8:1 while mixing at low speed with an electric mixer. Continue mixing until a uniform, lump-free, andsediment-free slurry is achieved. Let the mixture stand for 3-5 minutes, then remix for 1-2 minutes beforeapplication.
2.Do not add any extra materials beyond the specified ratio to the product, including but not limited to excesswater, cement, or river sand.

Interface agent construction

1.Ensure the substrate is free of standing water. Use a long-nap roller or brush, dipping it to the bottom of themixing bucket and rotating it to fully saturate with the bonding primer.
2.Lift the roller, gently tap it against the bucket edge, and then apply it evenly and generously to the wall surfaceusing upward strokes.
3.When used as a waterproofing material, ensure each coat is applied fully without misses. After the first coat hasdried, apply the second coat in a perpendicular (cross) direction.
4.Subsequent tiling work can only proceed after the Two-Component Waterproof Bonding Primer has fully cured.


Things to note

1.Application temperature 5~35℃, fully familiar with the overall application technology before commerce work.
2.Strictly follow the mixing ration to mixing specified stated, adding extra material is strictly forbidden.
3.This product contains cement, which produces alkaline substances in contact with water, so please pay attentionto protecting your skin and eyes.
4.Shelf life: the original sealed product is stored in a dry, cool, ventilated environment, under normal storage andtransportation conditions, the shelf life is 9-1212 months.
