the shellac needs to be cut more than 50%.....it needs to be a reduced to a 1 lb cut..generally,strait out of can is usually a 3lb cut..
this needs to be reduced 3 times....so basically you would use 2 gallons of of alcohol to 1 gallon shellac..
there is no need to condition or shellac a pine floor if you use proper technique.
if you sanded and prepared the floor well.
first..when initially beginning to stain..pick your point of start..
ring excess stain off rag over bucket so it don't drip or flood the floor...stain with the grain only.
this is basically "dry ragging" or dry brushing"....once you have a portion, not too large stained, maybe a 3x3 area..you
continue staining by putting the rag in the stain an coming out onto an already stained portion of the floor,
overlap what you have stained and continue staining with grain only...
Again, keep coverage areas minimal until you get the hang of it.
stain in even columns from wall to wall..( i know this sounds basic, but i have seen so many knuckleheads staining across grain in random patterns it makes me sick.)
as long as you dont leave to heavy a wet edge, and dont let sit long(which is why you work in small coverage areas only),, you will not get lap marks, drip marks, or uneven stain..this works for pine, fir and maple too....
been doing this since 91...so I'
ve learned a thing or 2..
