HCA-101 is sealed in 25kg plastic casks and transported in wooden cases. Each wooden case can be contained 36 casks of HCA-101.

 

HCA-101 material should be stored at dry places and protected from sun. The temperature in stored places must be higher than 0° C. The normal shelf life is 12 months.

 

HCA-101 is needed to be avoided insolation.

 

Application System

lConstructive System

The system is basically consisted of substrate, leveling course, waterproof coated membrane and protection layer.

 

lCoverage

2.5kg per m2 gives dft 1mm minimum. Coverage may vary with the substrate condition during application.

 

lApplication Method

Surface preparation

Surfaces should be stable, clean, smooth, without obvious water and free from any dusts, oil or loose particles. Cracks and surface irregularities need to be filled by sealants and do additional waterproofing.

 

Additional layer

Paint HCA coating as additional layer to enhance at internal and external corners, drain pipes, floor drains or embedded parts. When it uses reinforced materials, reinforced materials need to be coated on both sides.

 

Application of waterproof coating membrane

It is better to paint 2 or 3 times. It must be painted again after fully dry. The normal time between each painting is 8 hours. The direction of second time painting needs to be perpendicular to the first time painting.

 

Coated on the finished layer

Some water added in HCA will make surface more smooth and glabrous.

 

Application of protection layer

After waterproof coated membrane is fully dry and meets quality requirements, it can begin application of protection layer.
