I worked on 2 projects for painting a wood table and a metal table, where wet sanding had worked perfectly on the metal table while it ruin the wood table, as follow:-
I have a wood table which i painted using oil-based semi-gloss Jotun brown paint around 3 months ago. where there were many paint brush strokes.. so i decided to do a wet sanding for the table. i used 1200 grit sand paper + water. after wet sanding the table i cleaned the surface, but the sanding has created a white/dust-like surface, which will not go even if i use soap to clean the table for many times.
while on my second project, i have a metal table which i painted using Dulux oil-based satinwood white paint around 3 days ago. where there were many paint brush strokes.. so i decided to do a wet sanding for the table. i used 1200 grit sand paper + water. after wet sanding the table i cleaned the surface, and the surface had a glass-like finish and most of the paint brush strokes disappeared, which is what i were looking for.
so can anyone advice why the wet sanding worked on my white metal table and failed on my brown wood table? is it because wet sanding dark colors will not work? or because i wet sanded the wood table after 3 months of painting it unlike the metal table while i have painted only 3 days ago? Thanks.
