Warming up paint before application

[WayneS]

This winter I am going to repaint my hull (GRP) with International Toplac. The piece above the water line that is. I intend to apply with roller and finish with a brush.

I have been told by someone that the drying time can be reduced and the finish improved buy slightly heating the paint before application.

Anyone had experience of this idea?

Cheers

Yes it can help considerably especially if the temperature is low. It helps the paint to flow better without having to add more thinner. Before painting you should raise the temperature of the paint to about 25 degrees C. It will then flow much better than it would at a lower temperature and you will get a better finish.

Dont put the paint tin directly on the flame though!!
The trick is indirect heating called "bain marie". Ideally pour the paint into an old small sauce pan, clean. then place this sauce pan into another container with enough depth of water to warm up the paint, but without allowing the pan bottoms to touch, make a spacer if neccessary. Heat up the water, either on a stove or with portable immersion heater. Dont over do it. Heat wise that is.

The trick is to warm up the paint sufficiently to improve flow, off the roller and final brushing off, it works a treat.
Be careful though if you ever try this with two pack dont heat up too much or you could be shortening the curing time so much that it would harden in the pan.

Beware of fumes.

To get the best results I find standing paint in an old saucepan of warm water stirring paint occassionally. Beware though TOP LAC is not an epoxy paint an therefore will not give lasting performance as it is" softer" than epoxy. My advice would be to use an epoxy scheme providing an oil based paint has not been used previously.

Fair Winds!

I thought you could'nt leave epoxy paints exposed to light.Don't you mean poliurethane paint?

Safer method

Warm the water first.
Never put the paint "au bain marie" on the stove: the fumes might catch fire.

First warm the water, take it of the stove and THEN put the paint tin in it.
