| Here is a step-by-step preparation for exterior painting. As you go along, remember to check each point carefully.

| Surface problems are caused by moisture, frequent or
infrequent painting, and improper paint application. Small areas
of flaking or scaling are not a major concern; however, if there
are major surface problems ask your Benjamin Moore Retailer for advice. |
|
| |
| Shrubbery, walks, flower-beds, and patios are a target
for paint spills or drops and should be covered up. On flat surfaces,
hold down drop cloths with rocks or bricks in case of wind bursts. |

- Setting nails: sink nails below surface then spot prime, fill
depression with putty when dry, then sand and reapply primer.
- Remove scaling and flaking paint: use a broad scraper or wire
brush; sand edges to smooth down to original surface.
- Sealing: Seal to help prevent brown discoloration bleeding
from knots, cedar and redwood, through the finish coating.
- Sand glossy surfaces: paint will adhere better to rough surfaces.
Use sandpaper or wire brush. Look especially under eaves and
on trim.
- Putty: Remove and replace with fresh putty where necessary.
- Caulking: Re-caulk, where necessary, on all window and door
frames. This helps prevent moisture seepage which could damage
your finished paint job.
- Fasten loose boards: again, set nails and fill with putty.
- Wash exterior surfaces and rinse with clean water, especially
under eaves. Allow to dry before painting. Ensure any mildew
is removed.

| Metal surfaces include garage doors, siding, eaves
troughing and downspouts, flashing, vents, etc. If undamaged, treat
as any other surface to be refinished. Rust must be taken down to
bare metal by scraping or wire-brushing. Iron and steel require priming
with rust inhibiting paint. Galvanized metal requires cleaning with
suitable solvent followed by priming with a latex galvanized metal
primer. |
