AQUA FLEX SG500
Polyhybrid, elastomeric, liquid waterproofing membrane for flat roofs with timeless whiteness
Description
AQUA FLEX SG500 is a polyhybrid, elastomeric, water-based, liquid waterproofing membrane for flat roofs formulated with a blend of resins, featuring also timeless whiteness and durability. It has excellent adhesion to a variety of substrates, including concrete, wood, metal and any type of waterproofing membranes and is applicable even to irregular substrates. After curing, it forms a continuous, elastic, waterproof and vapor-permeable membrane, without seams or joints.
Fields of Application
AQUA FLEX SG500 is ideal for waterproofing flat roofs, curved roofs, etc. It constitutes a simple and safe waterproofing solution for roof details, such as corners, edges and joints between different adjacent materials, as well as for isolated cracks. Furthermore, thanks to its high solar reflectance, it can be used as a cool roof coating.

Directions for Use
Substrate preparation
The substrate must be dry, clean, free of grease, loose particles, dust, etc. Any existing cavities in concrete should be repaired in advance. The substrate is then primed with the special primer ISO-PRIMER with a consumption of approx. 200 g/m².
Full-surface waterproofing
As soon as the primer has dried, AQUA FLEX SG500 is applied by brush or roller either in two layers with a consumption of 0.5–0.75 kg/m²/layer, depending on the substrate. The second layer should be applied crosswise, after the first one is dry and walkable. In areas of severe cracks, reinforce with a 10 cm wide strip of fiberglass mesh (65 g/m²) or polyester fleece (30 g/m²). In cases of dense, multiple cracks, fully reinforce with 100 cm wide strips of fiberglass mesh or polyester fleece. Strips must overlap by 5–10 cm.
Local waterproofing of cracks
Prime cracks with ISO-PRIMER. Once dry, apply a layer of AQUA FLEX SG500 along the cracks. While still fresh, embed a 10 cm wide strip of fiberglass mesh (65 g/m²) or polyester fleece (30 g/m²) lengthwise. Apply one more layer of AQUA FLEX SG500 over the crack and reinforcement. Consumption: 0.3–0.5 kg/m (for a 10 cm wide strip).
