It all depends what type of gloss it is.
If it's trade gloss then it's absolutely fine to dilute it
Slightly with White spirit or a product called paint
Conditioner which loosens the paint without thinning it.
If it's non drip gloss then it's probably best to use it as it is.
If it's normal gloss then you can dilute it but only very
Slightly as it will leave you with sagging, drips and runs.
Hope this helps.
All the best.
yes it is ok with caution and care. There are specialist additives you can use or white spirit but only to an oil-based gloss paint product. First though stir the paint well beforehand then test on a surface with a brush If you cannot work with it add a small amount and again stir well.
However, I would not recommend or advise with any of the water-based acrylic gloss products.
