Features
- High-performance polymer additive for cement and concrete mixes
- Water-resistant, making it suitable as a temporary waterproofing sealer on rooftops
- High strength, ideal for patching and feathering with minimal cracking
- Non-toxic and safe for use without Occupational Health & Safety concerns
Benefits
- Water-resistant, enabling use as a temporary waterproofing solution for rooftops and similar high-exposure areas
- High strength, making it perfect for patching mortars, coving areas, and other demanding applications
- Non-toxic formulation ensures no significant occupational health risks
- Reduces the water-to-cement ratio, resulting in stronger, more durable mortar and screed mixes
Typical Applications
As a temporary waterproofing sealer in areas exposed to high moisture, such as rooftops, while new waterproofing membranes are being installed.
As a slurry coat applied prior to rendering or topping surfaces.
As an admixture for sand/cement mixes, particularly in repair mortars, fillets, coving, renders, and screeds.
As a bonding bridge for new concrete applied over existing concrete surfaces.
Limitations
Do not use E 135 mortar for tiling over concrete slabs that are subject to rising damp or hydrostatic pressure without first priming with AT 107 Water-Based Epoxy Membrane in two coats at a coverage rate of 3 square meters per liter per coat. Refer to the AT 107 WaterBased Epoxy Membrane data sheet for detailed screed installation instructions. Protect E 135 from frost—do not allow it to freeze. Do not apply E 135 as a temporary waterproofing sealer if rain is expected. Do not apply if the surface temperature is below 10°C or above
35°C.
