Application Instructions for SpECtite Polyurea H:
Surface Preparation:
The surface must be sound, of sufficient strength, clean, dry and free of dirt, oil, grease, and other contamination. The substrate must be primed with SpECtite Primer EP121 epoxy primer prior to application of SpECtite Polyurea H. SpECtop NS grains may be broadcasted over the primer for better adhesion properties if required.

Substrate Quality:
The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum pull-off strength of 1.5 N/mm². The substrate must be clean, dry, and free of all contaminants such as dirt, oil, grease, coatings, and surface treatments. Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured surface. Weak concrete must be removed and surface defects such as blow holes and voids must be fully exposed. Repairs to the substrate, filling of blowholes/voids, and surface levelling must be carried out using appropriate products from SpEC. All dust, loose, and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum.

Application Method:
Dose and mix with a suitable air-driven or electrical plural component heated spray equipment. Both components must be heated to a minimum of +70°C. The accuracy of mixing and dosage must be controlled regularly with the equipment. Thoroughly stir part A using a drum stirrer until a homogeneous colour is obtained. A spray trial should be done before commencing any work to set up the spray equipment properly.

Equipment Cleaning:
All equipment may be cleaned of uncured material using SpECtop Cleaning Fluid.

SpECtite Polyurea H is available in the following packaging:
Part A = 205 kg drums
Part B = 222 kg drums
The coverage rate for SpECtite Polyurea H is approximately 1.06 kg/m²/mm.
Layer thickness: 1.5 mm – 2 mm.
