FINISHING and Finishes, with Mr, Shiny himself – Kade Bolger!!
Top-coat vs Penetrating finishes. Durability of various finishes. Quick and Easy vs Longlasting. Some oils and waxes need to be continually replenished..!
Lacquers are fast drying top-coats, but lots of VOCs, smell, dangers. Easy to repair. Shellac is a topcoat build-up finish, easy to repair.
Polyurethanes and varathanes are plastic type top coat finishes. Very durable and water resistant. Can be thinned with varsol, mineral spirits, acetone, but acetone will eat away finishes, very tricky. BE Careful of vapours! Use good ventilation always.
Water based finishes can be thinned with distilled water (not tap water).
Water based finishes might raise the grain a bit and need fine sanding between coats. Oil based finishes tend to penetrate deeper into the wood.
Most oil finishes have an ambering effect.
APPLYING the finish: can wipe on some oils with blue shop towels that wont tear and leave micro shreds like paper towels can. Dip and wipe from wet to dry to cover the piece, overlapping strokes, avoiding excess dripping/pooling at the ends. Wipe off any remaining oil after 15-20 minutes. Softwoods and some softer hardwoods will absorb finish faster. Always work in the direction of the grain as far as possible. For finishing turned work, use interwoven cotton (t-shirt), gun-cleaning cloth is good to use (amazon). Apply, wipe off excess after 15-20 min, wait few hrs or longer depending on humidity, smell.
Can apply oil based over oil-based, wax can only be your final top coat.
Oily woods can take longer for a finish to cure fully. Wiping the oily wood with a varsol/etc may help, before applying finish.
Can do both dry and wet sanding, some use automotive sandpaper, torn not scissor cut to avoid aggressive edges. Can use the oil finish or water to wet-sand.
Soft sanding between coats results in better finish adhesion.
Can buff using ‘micro-mesh’ 1500 to 12000 grits, with water, as an alternative to other buffing methods. Wipe off any excess water/grit between grits.
Always dispose of oily rags in water. Saturate with water and store in a ziploc, keep in freezer! Oily rags can combust spontaneously!
