We do not recommend painting on a recent varnished surface or a surface that has recently been oil treated (like raw linseed oil treated surfaces). Surfaces like the above needs a 6-month curing time before paint work can be attempted.
We also don’t recommend painting onto floors.
Waxed surfaces and plastic surfaces need to be sanded first with 100 grid sandpaper and then thoroughly cleaned with Lacquer Thinners.
Surfaces like previously varnished surfaces (varnish older than 6 months), laminated surfaces, melamine surfaces, wall tiles, leather and faux leather need to be wiped clean properly using Lacquer Thinners. Use a mask and gloves and clean these surfaces well. Wait 20 minutes and then start painting. If it is a very oily surface cleaning will need to be repeated until all oily residues are removed.
