- How can I tell if my existing paint is latex or oil?
Take a clean rag with alcohol and rub an inconspicuous area. If color appears on
your rag you have latex paint. If nothing appears on your rag you have oil paint.

- How do I dispose of old paint?
Your trash man WILL NOT take wet paint in the can. However he will take dried up
paint. To do this, simply add sand, dirt, or even kitty litter to your paint and leave
the top off to dry. When it has dried up you can throw it away.

- What kind of brush should I use?
This will solely depend on the product you are using. If you have a latex paint,
varnish, or stain you should use a nylon (or nylon polyester) brush. If you are using
oil paint, varnish, or stain you should use a natural bristle brush.

- What size roller cover should I use?
Generally when rolling smooth walls with latex paint you can use a 3/8" nap cover. If
the walls are rough or seem to soak up a lot of paint you might use a thicker nap
such as 1/2". If you like more of a stipple you can also use a thicker nap (1/2" or
3/4"). Be careful not to use too thin of a nap (IE 3/16") because this has the
potential to cause more roller marks and lapping. You might use a thin nap (such as
3/16") when rolling oil on a smooth surface. Use a thick nap cover (3/4" or 1") for
porous surfaces (like block walls).

- What kind of primer should I use?
If you are priming new drywall you should use a latex based primer. Oil based will
fur up the paper and will then have to be sanded (making more work for you).

If you recently took down wallpaper and want to paint your walls you should prime
your walls with oil based primer. UNLESS you removed 100% of the existing glue,
water based products can activate the glue and cause it to bleed through your

The best primer for new wood (interior or exterior) is an oil based primer.
