Important Notes

1. Minimum ambient and substrate temperature is 5ºC.

2. Never apply more than 1 kg/m2 of PENTENS T-200 in one single layer.

3. Apply only to clean, sound substrates where surfaces should be well dampened but free of surface water and leaks.

4. Thoroughly agitate contents before use.

Instruction for Use

Surface Preparation

Surface must be sound, dry and clean (free of dirt, gravel, pollution, mildew and all foreign material). Do not apply if any rain is imminent. Repair flashings and damaged areas. Cracks and old bitumen joints shall be repaired first. On existing surfaces must be thoroughly cleaned before applying PENTENS T-200.

Remove all gravel. The main reason of applying gravel on the roof was to protect the old surface from the sun’s rays. Removing gravel will greatly reduce the weight load on the roof , and provide a firm surface for the new coating.

Sweep and vacuum or power wash surface to remove dirt and dust. Cut out roof blisters and repair with acrylic embedded in polyester fabric or polymer concrete.

Remove mildew with sodium hypochlorite or other algaecide and rinse with Tack down curled, lifted seams flush with the surface. Fill any other gaps with silicon impregnated latex caulk. Any loose shingles should be gently lifted and glued down with roofing cement.

Application

Substrate should be primed with a 1:3 mixture of PENTENS T-007 and water. Brush on at the approximate rate of 0.3kg/m2

On areas exposed hot drying winds. 2 to 3 thin coats of paint may be more successful than 1 thick coat.

PENTENS T-200 is suggested to apply at least 2 coats. The first coat should be applied in one direction only. If possible the second coat should be applied at right angles to the first.

Leave to cure for approximately 8 hours before applying second coat. PENTENS T-200 can be installed with conventional airless spray equipment, brush or roller.

Consumption

On concrete roofs: 1 kg/m2/per coat

On facade/vertical: 0.5~1 kg/m2/per coat

Curing

Allow the coating to cure thoroughly before applying the next coat. 1–8 hours of wait period, depending on temperature, humidity and wind conditions.

Cleaning

Tools and equipment just can be clean with clean water immediately, after use. Harden material can only be mechanically removed.

Safety

PENTENS T-200 is non-toxic. For personal precautions, applicators are recommended to wear gloves and goggles when handling
