Having a first time dabble with water based paint for skirting and door frames - Johnstones Aqua range.

Coming from solvent based, it really is a completely different experience. My first attempt seems to have gone ok but one thing I did notice was despite going at a decent place, my brush seemed to be drying out. Has anyone else experienced this?

Any additional tips for painting wood work and internal doors with water based stuff?

Thank you

My top tip for water based paint:

Lay it on, flat it out, leave it the fk alone.

If you attempt to go back and touch in a missed spot for example, it'll just end up in a mess. Catch any defects with the second coat, or once it is fully dry.

Thin coats and work quickly.

I tend to dampen the brush a bit before starting, seems to make laying it on a little easier,

I also prefer to use a roller wherever possible to get a flat finish,

I've found that mini varnish rollers work best

I didn’t don’t find it too bad doing thin coats, but it was a lot of thin coats in the range of six until I was happy with the appearance and brush strokes etc.

Once done it's very easy to overcoat if it starts looking tired.

Isn't this why people add a paint conditioner like Floetrol or whatever?

Yes, you cant go back to it once it has skinned, which happens fast, so as said lay it off quickly and leave it alone.

You also need a synthetic brush, if you are coming from using a natural birsle brush with the oil paints.

My preference is an Oldfields 'Oval Wall brush' following recomendation elsewhere on pistonheads.

My preferred paint is Little Green 'Intelligent eggshell' in flint.
