A plaster vent grille is today’s snapshot inside a Spanish-style home being built in Santa Barbara, CA. Follow me as I continue to share photos of the design and construction of this custom interior where many different classic Santa Barbara materials and finishes were incorporated.

A variety of sizes for this decorative plaster vent grille design were installed throughout the home. 6 x 12 and 6 x 14 are fairly common sizes for ceiling and wall vent covers. The large size shown here was custom designed for the two clean air return vents in the house.
Depending on the size of your home and HVAC system (Heating, Ventilation and Air Conditioning), you most likely will need to consult with an air flow specialist who is familiar with plaster grilles. Your architect or General Contractor will help guide you in getting the proper sizing.
There is a mathematical formula that is used to figure this all out. For starters, it involves calculating the square footage of your home with the ceiling heights. This is the volume of air in your home.
The size of your FAU (Forced Air Unit/heater) is also reviewed. How much air flow your unit is capable of. Some plaster grille designs restrict air flow more than standard grille covers, so to be safe all of this has to be figured out on your behalf.
Inspiring Spanish Home Experts: The Detailists

Here, the Artisan drywall expert touches up the walls before the interior wall painting begins. He is using a combination of tools to do this.
A standard putty knife to knock down any leftover rough or sharp edges, and the specialty sponges he is holding in his left hand.
The angled sanding sponges come in many different sizes and shapes. They can be used “dry” or wet, are used to literally sand the blemishes in the drywall finish. The soft grouting sponges are typically soaked in clean water, squeezed mostly dry and used to softly blend everything together.
