Finishing Exterior Wood Shutters

Priming Wood Shutters

Preparation

Exterior wood shutters take a beating from the elements, that.s why we take special care with our factory finishes to make sure that your shutters will have a long life of trouble free use. After each custom shutter is completed, it is machine sanded, and then hand sanded to prepare the surface for the final finish. After inspection and hand sanding, the shutters are blown off with high pressure compressed air and moved to our environmentally controlled paint rooms.

Priming

Most exterior wood shutters are made from cedar, and depending upon the species that is being used, cedars have a high level of tannic acid that is ideal for preventing fungus, mold and insect activity, but can be create difficulties in painted finishes. As such, we use a specially formulated oil based primer that has stain blocking features. The primer is designed to be absorbed into the wood grain and to give an excellent surface for the finish coats of paint.

Scuffing

After the shutter has been primed, the primer.s action will slightly raise the grain of the wood as it is absorbed into the dry wood fibers. The next step in our process is to lightly scuff sand all surfaces of the shutter to remove the raised grain, and to provide a flat smooth surface for the optimal adhesion of the top coat. After the scuffing, the shutters are again cleaned with high pressure air before moving into the painting process.

Note: For customers who are ordering shutters factory primed, but who plan on applying the top coat on-site, Estate Millwork does not scuff sand the shutters prior to shipping. This allows the shutter to remain sealed for transit, and protects the wood from absorbing moisture which will cause problems later in the life of the shutter. It is a simple matter for the customer to quickly scuff the primer prior to painting. Each primed shutter will be carefully wrapped prior to shipment.

Painting Wood Shutters

Post Priming

After each wood shutter has been factory primed by our quality process, the shutter is re-inspected and scuff sanded to prepare it for spray application of the top coats. Estate Millwork has specialized fixtures and jigs that enable us to easily apply top quality finishes, and the scuffed shutter is loaded into a fixture in our environmentally controlled, industrially vented spray rooms.

First Top Coat

Estate Millwork uses high quality Sherwin Williams paints for maximum durability, and can match any color from the Sherwin Williams system, or even paint numbers from other manufacturers. We use latex paint because it bonds well to our primer, and has the ability to live and breath with the wood underneath as the various weather elements work against the shutter. The first top coat is applied evenly to the primer and will fill in any of the scratches left by the scuff sanding, and is allowed to air dry for maximum finish quality.

Second Top Coat

After the first top coat is dry, the shutter is given a second top coat that gives the shutter double the protection against the elements. The combination of primer, scuff sanding, and two top coats gives an unmatched finish, and often saves customers the aggravation, expense and space requirements of painting their own shutters.
