When should you begin painting after stripping a surface with the Speedheater IR Paint Remover?
As soon as possible, preferably the same day as the moisture level will normally be as low as 8-10%. Ideally, use a damp
Plastic paint straight onto wood?
Use the same method as for old, dried-out paint layers.
Minimal. The operating temperature is normally just 100-200°C and only the irradiated surface becomes warm, in contrast to the 400-1000°C produced by a hot air gun where the air can get into cracks and start a fire on the back side of the panel.
The parts of a building most susceptible to fire are roof footings and around window and door frames.
If you prefer to err on the side of caution, spray water onto roof footings and on the underside of the roof with e.g. a spray bottle before applying any heat. Water usually makes the process of paint stripping easier and is dried out by the Speedheater IR Paint Remover.
How is the wood affected?
Moisture is drawn out and natural resins and rosins melt and are brought to the timber surface, which inhibits the ability of the wood to draw in more moisture. This ensures good adhesion for the paint and extends the life of the paint layers.
