Here you will find frequently asked questions.

What is the waiting time before the system can be turned back on?

Approximately 10-15 minutes. The coating does not need to be dry.

What is the waiting time before ducts can be re-coated (at 20 degrees C)

24 hours. We always inspect the system 24 hours after coating, to ensure and document the quality. The system can be re-coated after 24 hours if more than one layer is needed.

What is the recommended wet film thickness?

215 µm (=120 µm dry film thickness). Total recommended consumption for optimal protection (VentGuard SC50): 400 g/m2 = 120 µm dry film thickness).

What is the minimum size/maximum?

The smallest we can clean, and coat is 70mm. Standard sizes below. If you have specific measurements in mind, please let us know and we will find a solution that fits your need.

The following is our standard sizes:

1. Round, standard sizes: R80 mm, R100 mm, R125 mm, R160 mm, R200 mm, R250mm, R315 mm

2. Square, standard sizes: 80 x 80 mm, 100 x 100 mm, 150 x 150 mm, 100 x 150 mm, 200 x 200 mm

What materials can the coating be used on?

Concrete, plastic, stainless steel, and galvanized/ungalvanized are the most common material for us to work on. But the coating can be used on any surface, if it is not too porous. To ensure adhesion surfaces should always be clean and free of dirt, dust, rust etc. prior to coating.
