is that the problem/complaint, or solution to others problems/complaints?
Very philosophical question Johnny....

No bubbles?I recently varnished mine with a long-handled roller for painting ceilings. Quick work, very little bending, would recommend.
An astute question. Where I followed the instructions and applied three coats, no bubbles. However, I flew too close to the sun. In my high-traffic area I applied FOUR coats, and didn't sand in between, and it is a little textured. 'Bubbles' isn't the right word, but maybe a little dimpled.No bubbles?

Not looking to crosstalk anyoneThe bubbles are more to do with viscosity or surface condition than than they are with the application method.
*puts on chemistry face*Paints are chemically designed to have a viscosity that when the medium (water/oil) flashes off (evaporates) it capillary actions itself into a flat surface. If the paint is stirred to kindom come and the wall is clean and free of moisture than even roller bubbles will dry flat.

Water isn’t a medium, it’s a solvent. If it evaporates without a trace, it’s a solvent. The medium is the chemical left behind that gives the finish and the pigment gives the colour. Acrylic in craft paints is a common medium, without pigment it dries to leave a transparent film behind (usually using water as a solvent). Oils are both solvents and media, they mostly evaporate away but leave more or less fatty residues behind to also act as a medium. You can dilute your paint with either a solvent or more medium, using more medium usually will make it more workable but disperses the pigment better to keep the colour intense (whereas water will make it more washed out). Very little of this is relevant to painting a house though.
A lot of varnishes will say that, precisely because they don't want the bubbles that stirring will createinteresting how some paints have a 'do not stir' instruction on the tin. i never understood the rationale.
One month later… level 3410.Two Dots level 3202
Levels get more difficult as it goes on.
YOU THOUGHT WRONGI don't think anyone here is using linseed oil on their walls, nerd
This is floors and it's varnish
Your varnish medium will pool on floors. This isn't theory, it's experience. and an understanding of gravity's effect on liquids.
