7. Troubleshooting
Issue Possible cause Possible solution
Uneven curing

Emitter not properly pointed/ad-
justed to the curing surface

Adjust emitter properly to the cur-
ing surface
Small pores (bubbles)
on the cured surface

Emitter too close to curing sur-
face

Curing too fast

Paint with fast thinning agent

Increase distance

Increase pre-curing time

Use standard or slow thinning agent
Poor curing or trans-
parent coating

Emitter too far away from curing
surface

Curing time too short

Paint layer too thick

Decrease distance

Increase full-curing time

Apply thinner paint layer
Stains

Full-curing time too long

Emitter too close to curing sur-
face

Decrease full-curing time

Increase distance
Fuzzy edges

The painted surface area is too
large for the infrared emitter

Curing in two steps

Move device for second curing step

Pre-curing only for first step. Do not
use pre-curing for second step.
For optimal curing performance, we recommend to work out the optimal operating procedures, cur-
ing times and distances according to the local natural conditions, working environment and the types
of paints used.
