APPLICATION

Surface Preparation

All substrates shall be sound and clean free from dust, excess mortar, oil or other loose particles.

Cracks or honeycombs shall be repaired using suitable cement mortar.

CREATION OF SURFACE CONDITION

Over excessively dry substrate, keep the substrate continuously moist before work begins. Remove all excess water or standing water, allowing the surface to become almost dry to provide an SSD (saturated surface dry) condition before installing the waterproofing coating.

PRIMING

For over excessively dry and porous substrate, prime the entire surface with Bostik Multiprime prior application of the waterproofing coating with the rate of 5m per liter depending of the substrate condition.

MIXING

Mixing ratio of 2 parts powder to 1 part of liquid by weight.

Mix in a clean container by slowly adding the Powder component to the liquid component whilst stirring using a slow speed heavy-duty electric mixer with a suitable paddle.

Mix until homogeneous slurry is obtained and make sure that no unmixed powder is left at the bottom of the container. Small amounts may be hand-mixed separately.

PLACING

The mixed Boscoflex can be applied onto the prepared substrate using a bristle brush or roller, place the material well into the surface to achieve full bond.

The application of Boscoflex waterproofing coating shall be done in a minimum of two (2) coats, the first coat in one direction and the second coat in a direction perpendicular to the first coat. Apply the subsequent coats after 2-4 hours curing of the previous coat.

Minimum 2 coats at approximately 1.0kg/m per coat.

For areas subject to high water infiltration, apply a third coat at 1.0kg/m .

Allow at least 24 hours curing of the finished coat (subject to

23 C and 50% relative humidity) before laying screed or tiling. Water test can be conducted after the same duration.

CURING

Special curing methods are generally not required but some precautions should be taken from rapid drying for application directly under sunlight and windy conditions. Curing of Boscoflex shall be at least 24 hours before trafficking, to yield optimum strength.

CLEANING

All tools, equipments and surrounding areas can be cleaned with clean water before the product sets.

Hardened material has to be mechanically removed.

PACKAGING

Boscoflex is packed in 30 kgs set.

Part A: White liquid; 10kgs

Part B: Grey Powder; 20kgs

RECOMMEND COVERAGE

1. Ground moisture - 2kg/m ; 2 coats at 1.0kg/m /coat.

2. Hydrostatic Pressure - 3kg/m ; 3 coats at 1.0kg/m /coat.

Note: Do not apply more than 2kg/m of Boscoflex in a single layer.

STORAGE AND SHELF LIFE

Boscoflex has a shelf life at least 12 months.

Store all materials in a cool dry place, in an elevated condition.

HEALTH AND SAFETY

Suitable protection clothing, dust masks, gloves and eye protection should be worn. Continual or extended contact with cement products can cause skin irritation. If skin irritation occurs, flush skin with water for a minimum of 15 minutes. If irritation still persist, consult medical advises
