Hi mates, being based in Spain, is difficult to use the same brands of finishes that you are using to I will skip brand names here, and they won´t make sense :-)
Issue I have is happening with three different brands of water based poly. All of them are quite thick, kind of almost gel consistency, but they flow very well when used. the problem I have is that when applying them, even with the lightests of my brush strokes, or with a foam pad, I´m getting very tiny bubbles all over the place. If I overbrush with only the tip, very slow and faintly, I get rid of some of them, but the remaining will be perceived when totally dry. A quick rub with fine sandpaper, solve the touch issue, but the bubble shapes remain as tiny circles on the wood. That is not a big problem in heavy figured woods, but on clear dark ones, they show as a shore thumb when the light strikes skewed.
Have you find this problem before? I tried with good quality synthetic and natural brushes, foam pads and even with cloth, but I always had the same issue. The cans were not shaken but stirred, and I avoided to discharge the brush against the lid, as some googling suggested… I´m running out of ideas.. could the that is too thick/liquid?
Any suggestions is more than welcome, I prefer to test 20 different solution than fry my brain thinking in what I´m doing badly….
Many thanks in advance, and regards from Spain!
