Features

• Good penetration into absorbent and chalky surfaces.
• Easy to apply.
• Good binding properties.
• 100% lead free.

Intended Usages

• For bonding powdery and chalky surfaces.
• For bonding previously lime-washed surfaces.
• For bonding chalky PVA surfaces.
• For bonding chalky cement roof tiles.
• For bonding chalky off shutter concrete.

Application Details

• Mixing: Stir well before use with a flat paddle to an even consistency. Stir occasionally during use.
• Method: Roller or brush.
• Thinning: ProGold Mineral Turpentine.
• Cleaning: Remove as much of the product as possible from the application equipment before cleaning with water ProGold Mineral Turpentine.

Conditions:

• Temperature between 5°C and 40°C.
• Relative humidity of less than 85%, preferably between 10:00 and 16:00.
• Ideally apply when the temperature of the substrate is at least 2°C above dew point.
• If possible away from direct sunlight.

Drying time:
Surface dry: 4 hours, Hard dry: 16 hours at 23°C.
Note: Higher temperatures will accelerate the drying times (approximately halved for every 10°C increase), whilst lower temperatures will retard the drying time (approximately doubled for every 10°C decrease).

Recoating time:
18 hours to maximum 48 hours at 23°C.

Requirements:
1-2 coats (test efficacy by using the masking tape test).

Surface Preparations
New, sound plaster:

• Ensure the plaster is dry.
• Brush down well to remove as much of the loose material as possible and then apply directly.

New, friable plaster:

• Ensure the plaster is dry.
• Brush down well to remove as much of the loose material as possible.
• Apply a coat of Prominent Trade Bonding Liquid diluted 20% with ProGold Mineral Turpentine.
• Apply second coat undiluted.

Friable floor screed:

• Not recommended.

Chalky PVA:

• Remove chalkiness by high pressure water washer at 180 Bar with a rotating nozzle or ProGold General Purpose Cleaner/water mixture (1:10) and a nylon scrubbing brush.
• Rinse with clean water, allow drying and then apply a coat of Prominent Trade Bonding Liquid diluted 20% with ProGold Mineral Turpentine.
• Apply second coat undiluted.

Lime-wash:

• Remove chalkiness by high pressure water washer at 180 Bar with a rotating nozzle or ProGold General Purpose Cleaner/water mixture (1:10) and a nylon scrubbing brush.
• Rinse with clean water, allow drying and then apply a coat of Prominent Trade Bonding Liquid diluted 20% with ProGold Mineral Turpentine.
• Apply second coat undiluted.
• In both cases is it necessary to perform a cross hatch adhesion test to ensure proper binding of the substrate before the final finishing application commences.

Limitations

• Cannot be applied to damp surfaces.
• Too much penetration can occur, thus no bonding takes place on the surface and would require further coats.
• Product must not be applied to leave a varnish-like surface and then recoated.
• Product must penetrate the surface to be bonded and thus it must be applied directly to the plaster.
• Cannot be used on enamel finishes or steel.
• The product has poor UV resistance, so it should be overcoated.
• Product must only be overcoated once completely dry.
• Cannot serve as a primer for Prominent Stoep Enamel or Prominent 2-Pack epoxies.

Safety

• Keep out of reach of children.
• Ensure to maintain good ventilation during application and drying process.
• In case of skin contact, wash with soap and water or a recognised skin cleaner. Avoid contact with eyes. In case of contact with eyes rinse immediately with running water and seek medical advice.
• If product is ingested drink plenty of water. Do not induce vomiting at any time. Seek medical advice.
• Refer to the Material Safety Data Sheet (MSDS) for detailed information about the product and transportation and classification criteria. MSDS is available on www.prominentpaints.co.za or from Prominent Customer Service Department.
• To avoid any risk of spillage, always transport in a secure upright position.
