Select Bonding Liquid

Features

• Good penetration into absorbent and chalky surfaces
• Easy to apply
• Good binding properties

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: ProGold Mineral Turpentine

Conditions:

• Temperature between 5°C and 40°C
• Relative humidity of less than 85%, preferably between 10:00 and 16:00

Drying time: 
Surface dry:  4 hours; Hard dry:  16 hours at 23ºC
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 48 hours maximum at 23ºC
Requirements: 1 - 2 coats (test efficiency by using the masking tape test)

Surface Preparations

Surfaces must be sound, clean and dry (moisture content below 15%) before painting.

1. New work:
1. 1 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.
1. 2 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 Select Bonding Liquid diluted 20% with ProGold Mineral Turpentine. Apply second coat undiluted.
1. 3 Friable floor screed: Not recommended

2. Redecorating:
2.1 Chalky PVA : Remove chalkiness by high pressure water washer 200bar / 2900psi with a rotating nozzle or ProGold General Purpose Cleaner diluted 1:10 with water and a nylon scrubbing brush. Rinse with clean water, allow drying and then apply a coat of Prominent Select Bonding Liquid diluted 20% with ProGold Mineral Turpentine. Apply second coat undiluted.
2.2 Lime-wash : Remove chalkiness by high pressure water washer 200bar / 2900psi with a rotating nozzle or ProGold General Purpose Cleaner diluted 1:10 with water and a nylon scrubbing brush. Rinse with clean water, allow drying and then apply a coat of Prominent Select Bonding Liquid diluted 20% with ProGold Mineral Turpentine. Apply second coat undiluted.

In all cases, it is necessary to perform a cross hatch adhesion test to ensure proper binding of the substrate took place 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 must it be applied directly to the plaster
• Cannot be used on enamel finishes or steel
• The product has poor UV resistance, and thus should be overcoated
• Product must only be overcoated once completely dry
• Cannot serve as a primer for Prominent Stoep Enamel or 2 Pack Epoxies
