Plastic sheathing and masking tape was not available at the end of the painting project for whatever reason, I have no idea, but you have a Paint Brush that if not cared for will eventually dry up. Last solution that works well, is to take a sopping wet rag, wrapping the Paint Brush up like that burrito you missed wrapping up earlier. This will buy you some time until either you use the paint brush again, or you can properly clean it.
Like this, it will actually take quite a while to reach a number that is close enough to the yellow color you've chosen that you can't tell any difference (and mathematically, you will never actually reach an average of 4!)
Choose from historical hues for period homes; sleek chalky finishes that stand up to the rigours of modern life; or new formulas designed to suit all surfaces. By understanding the product you can unleash all the design possibilities of paint that make it such a tempting medium.
You can put it around a room and probably follow immediately with the finish coat. It can be applied with brush or roller.

If you have a timber floor that's not particularly attractive or is made from a patchwork of old and new wood, paint makes the perfect disguise. There are plenty of choices - all the colours from Farrow & Ball are available as floor paint and Nordic Style offers an elegant selection, too.
Painting ceiling does not require premium paint. You can use flat $15 to $20 ceiling paint. I use Sherwin Williams PRO-MAR 200. Painting ceiling requires a lot of physical work and plenty of drop cloths. If you are not up for the challenge or have very high ceilings contacted a professional will prove to be a smart move.
