If you are using a methylene paint remover, you remove the sludge
first. Often takes more than one application,
depending on amount and character of old finish being removed. Nasty
stuff, so you need good ventilation and
protection for other surfaces. With the final application, I use medium
steel wool to scrub the surface, then a
scraper to remove it, a last wipe with s.w. to get as much of the
stripper as possible. I then use fine s.w. and
mineral spirits to scrub off the last of the stripper (for wood or
metal) and a last wipe with paper towel. You
want to be sure to wipe off as much of the waste as possible, including
fine little shreds of steel woo.l. Semi-
paste stripper usually has wax as a thickener and the wax will interfere
with new finish if left on. If you have left
an initial application of stripper on a surface and it has dried, no
problem. Just apply another thick coat, let it
work for ......20-30 minutes or so. Best not to work with it in sun or
wind, as it evaporates too quickly to get
best results.
