Spend the Money... Cheap verathane will not last. Buy the professional quality verathane for a durable finish.

We are using a paint tray with a liner, a broom handle and a wool verathane application head. Rule #1, Apply the verathane in even coats with the grain of the wood. #2 Maintain a wet edge. #3 don't paint yourself into a corner!

Slow smooth motion will avoid air pockets within the finish.

Don't apply too much at a time or you will have puddles. Give it 3 or 4 good even coats for a durable finish. Again, I can't stress this point enough. $30.00 verathane will not last as well as $100.00 verathane. The better materials are nearly often worth the extra money!
We actually had this color custom tinted by our paint store. It was a combination of 3 different colours in an effort to closely match a pine floor adjacent.



The machine blow is called an edger. This has a spinning disc and casters or wheels at the back. It tilts forward and is used for sanding close to corners and walls. IN the same way you use coarse paper and work down to smoother finish as you work.
