Higher in styrene content than paint-grade SAE, construction-grade formulations deliver the combination of water resistance, UV stability, and mechanical durability required for GCC roof waterproofing, below-grade membranes, and facade coatings exposed to the Gulf's extreme UV radiation and thermal cycling.

Applications
- Elastomeric Roof Waterproofing GCC — Primary binder in elastomeric waterproofing coatings for flat and low-slope roofs across GCC residential and commercial buildings. UV stability and high elongation (200–600%) accommodate the thermal movement of GCC roofs — where surface temperature cycles from 15°C at night to 80°C+ in summer can cause 5–10mm movement per meter of roof length.
- Below-Grade & Basement Waterproofing — Used in polymer-modified cementitious and pure acrylic waterproofing coatings for below-grade concrete structures, foundations, and underground car parks — particularly relevant in coastal GCC cities where groundwater salinity creates aggressive waterproofing conditions.
- Concrete Sealer & Carbonation Protection — Applied as a diluted sealer coat on GCC concrete facades to prevent carbonation-induced corrosion of reinforcement — a critical durability issue in GCC coastal environments.
- Podium Deck Waterproofing — High-build SAE-based waterproofing systems for podium decks on GCC mixed-use developments — provides waterproofing beneath hard landscaping and planters.
- Polymer-Modified Cementitious Coatings — SAE emulsion used as the liquid component in 2K polymer-modified waterproofing slurries, improving flexibility and water resistance vs straight cementitious systems.
Key properties
- High UV stability — no yellowing or chalking under GCC solar radiation
- High elongation (200–600%) — accommodates GCC thermal movement cycles
- Excellent water resistance and low water uptake
- Good adhesion to concrete, brick, and cementitious substrates
- MFFT ≤ 5°C — film formation in GCC winter conditions (minimum ~10°C)
- Compatible with TiO2, iron oxide, and mineral fillers
- Breathable film — allows moisture vapour transmission from substrate
- Film maintains flexibility across GCC temperature range (-10°C to +80°C)
Usage and recommendations
For roof waterproofing membranes: formulate at 45–55% solids with TiO2, calcium carbonate, and appropriate additives for a minimum 200 μm DFT (2-coat system recommended). For concrete sealers: dilute to 20–30% solids and apply by brush or spray at 200–300 g/m². For 2K cementitious waterproofing: use at 1:1 to 1:2 (emulsion:powder, by volume) as specified. Always apply to damp (not wet) concrete surfaces — dry surface absorption reduces adhesion. On GCC horizontal surfaces exposed to UV: use a white or reflective pigmented formulation to minimise thermal load.

Storage and shelf life
Store at 5–35°C. Do not freeze — freezing permanently coagulates the emulsion. Keep sealed. In GCC summer: store in shaded, temperature-controlled areas to prevent over-heating. Shelf life: 12 months.
