How to apply Bostik ET-150

How to apply Bostik ET-150: Bostik ET-150 Sprayable Vapour Barrier Coating has been designed as a shielding layer when working on surfaces that have a high risk of containing hazardous substances such as asbestos. It is generally associated with being an asbestos encapsulant and a protective coating for internal and external insulated piping equipment and air conditioning ducting.

All work related to the removal and disposal of asbestos should be carried out in line with regulations and best codes of practice. This ensures construction workers are not exposed to airborne fibres on a job and protect friends and family from secondary exposure.  

Apply Bostik ET-150 with a brush or spray. When it dries, it forms a durable, water-proof and flexible finish.  

Bostik ET-150 is solvent-free, and fire tested to ensure it retains all its’ protective properties of polymers. 

Firstly, check the relevant coverage rates required for your job. 

Apply the specified minimum coverage rates below for the best results.

It is important to follow asbestos regulations when carrying out this kind of work. For more information, read ARCA’s ‘Guidance for the Encapsulation of Asbestos Containing Materials‘ or refer to page 62 in WorkSafe New Zealand’s ACOP: Management and removal of asbestos

How to use Bostik ET-150

Getting ready:

1.    Ensure the area is clean, dry and free from dust and oil.

2.    Bostik recommended that you have two different colours, this is so it is clearly visible when a full and even second coating has been applied.

Application 

Internal: Spray or brush on two coats, each at a rate of 3.2m2 per litre to achieve a dry film thickness of 0.5mm.

External: Spray or brush on two coats, each at a rate of 1m2 per litre and then a further second layer at a rate of 1.5m2 to achieve a dry film thickness of 0.8mm.

3.    To test if your coatings are dry, rub the surface gently with a damp cloth. If no colour rubs off, the layer is dry.
