Estoflex Solar 790
Hybrid Polyurea Waterproofing Membrane
Description
Estoflex Solar 790 is a ultra-fast spray applied hybrid polyurea, 100% solids pre-heated, flexible, two-component hybrid polyurea elastomeric, designed as a waterproofing and protective coating with excellent resistance to common chemicals. The seamless coating provides an elastic yet tear resistant surface for applications subjected to extreme wear and tear, strong impact and chemical exposure. As with all aromatics, over a period of time colour change will occur if exposed to UV rays. This will not have any negative effect on the physical properties of the product. It is suitable for outdoor applications and available in wide range of attractive colours.
If long term aesthetics and excellent UV resistant is require, then spray/roller apply Estoflex Solar TC60 as top coat over Estoflex Solar 790 at a rate of 0.3kg per m². This is recommended for exposed system only.
Uses
Estoflex Solar 790 is suitable for indoor and outdoor applications. It is suitable for the following applications:
- Indoor and outdoor floor slab
- Basement waterproofing
- Anti-corrosion coating for buried and submarine steel pipes
- Sewage treatment plants
- Secondary containment for chemical tanks
- Waste water tanks
- Roof Waterproofing
Advantages
- Environmental friendly – zero VOC
- Seamless and rapid curing.
- Attractive – provides a very smooth and aesthetic surface in a wide range of colours.
- Hard wearing – exhibits excellent abrasion resistance.
- Elastic – bridge cracks on concrete surface.
- Non-skid – excellent grip.
- Chemical resistant – very good resistance to many cleaning chemicals.
- Not sensitive to environmental conditions during application.
- Suitable for extremely temperature (-50°c to +130°c).

Application Instruction
Surface Preparation
Concrete surface should be clean and free from oil, grease and other contaminants. New concrete shall be allowed to cure for at least 28 days before application of primer. The ideal mode of surface preparation for concrete is abrasive blasting.
Steel surface shall be free from oil and grease. The surface to be coated shall be dry abrasive blasted to SA2.5 in accordance with ISO 8501-1.
Priming
Recommended to apply Estoprime PU Primer T-117 at rate of 0.2kg to 0.3kg/m² on the well prepared concrete substrate and allow to dry.
Application
This material is designed for application with heated, plural component airless spray equipment.
The transfer pump of at least 2:1 ratio is required to prevent cavitations of the proportioning pump.
Because of the relatively high viscosity and fast reactivity of this product, pressure of at least 1,600 psi is required to ensure satisfactory mixing.
Top Coat (For Exposed System Only)
Recommended to apply Estoflex Solar TC60 at the rate of 0.3kg per m2 as a top coat for Estoflex Solar 790 protection for exposed area only.
