Bob talks to Ed Waller from CertaPro Painters about painting of the guest bedroom in the Melrose, Massachusetts, project. Waller explains that the paint being used is a latex paint which does not contain VOC's (volatile organic compounds). As a result, the room is free from noxious odors even as the paint is being applied. The no VOC paint actually holds to the walls better and is only a little more expensive than conventional paints. Two coats will be applied in this project so no spots are missed. Bob notes how the paint is being applied over the molding. Waller explains this is so no spots are missed and when they go back to paint the trim, a craftsman will paint with precise, straight lines to cover any molding gaps where it meets the wall. Bob is surprised that the radiator has been painted, but Waller says old radiators are often painted with latex paint with no negative effect on their heating ability. Bob asks how to find a good painter. Waller looks at the previous work they have done and who they have worked for, then trains them properly with full supervision in the field. Waller encourages the use of an extension pole when painting as, for a minor cost, it helps the painting process greatly. Weller also encourages painting in a direction from floor to ceiling to apply the paint evenly across the wall. When it comes to painting the trim, the crew uses a semi-gloss no VOC paint from the Sherwin Williams Harmony line. The primer that was used was also a no VOC paint from the same line. Painting the trim requires a steady hand and is the measure of a good paint job. Expensive brushes with synthetic, flared bristles are used while painting latex on the trim. Waller reviews proper painting technique using a pail to hold the paint, and gently tapping the sides of the pail with the brush to get rid of excessive paint before applying. Weller also gives tips for painting older panel doors. The door is painted entirely by brush rather than roller and work is done with tough stuff first working inside to out, top to bottom, and left to right. Bob reminds viewers to tape the hinges and remove the doorknobs and keyhole covers before painting. The tape is removed before the paint dries completely.

Bob checks out the paint job on a Habitat for Humanity Blitz Build project, where he finds out about exterior paint that can be applied at temperatures near freezing and low VOC paints that have a low odor during application and dry time.

Now colder weather doesn't have to be an issue when doing exterior painting. While most conventional paints must be applied above 55 degrees fahrenheit, cold weather paints are designed to resist moisture, frosting, and blistering in temperatures as low as 35 degrees. They're safe for most any surface, and can be applied just like conventional paint, with a roller or brush.

Here's another great tip from BobVila.com. There s more to that new paint smell than you might think. There are already federal restrictions on them because they re damaging to the ozone layer, but more and more studies are showing that volatile organic compounds, or VOCs, are dangerous to humans. VOCs are found in paint and lots of other products that contain solvents and petrochemicals. Their concentration can be 10 times higher indoors than out, especially right after a home improvement project. While most VOCs will dissipate on their own as the paint dries, they continue to off-gas at low levels for years. Ventilation is key during and after any paint job. Never use exterior paint indoors, and wait several days before moving into a room that s just been painted. High-level exposure to VOCs has been linked with eye and breathing problems, headaches, nausea, dizziness and even cancer. Children and asthma sufferers are especially vulnerable. Because of these health concerns, paint manufacturers have been putting a lot of effort into new lines of low- and no-VOC paints. Petrochemicals are what make up 5 to 15 percent of standard latex paints and about half of oil-based paint. That s about 450 parts per gallon. Until recently, these toxic chemicals were what made the paint work well. Now, to qualify as low-VOC paint, they must contain 100 parts per gallon or less and still do a good job. Non-toxic paints have lots of benefits, but one of the greatest is easy cleanup. Because it s not considered a dangerous substance, you can clean up the mess with soap and water and dispose of the cans in your regular trash.

Bob meets with Pat Estevez to discuss exterior paint selection and application techniques. Several paint colors are being used to accent the kitchen addition. Acrylic paint is used to stand up to the harsh sun and resist mildew.

The clapboard siding on the modern Colonial is being prepped and primed with Bob Vila Signature Collection paints. Bob is on hand as painter Jon Fish first sets, or recesses, any protruding nails securing the clapboard siding to the exterior sheathing. Next, in the corners where the clapboard siding butts up against the home's cedar shingles, the gaps are sealed with a fast-drying, paintable caulk. Caulk is also applied around window trim to prevent water infiltration. The caulk is applied with a caulking gun, and any excess material is wiped away with a damp rag. Fish then shows proper technique for painting clapboards. Beginning with the corners and side, Fish starts at the bottom of each clapboard then works across the board. Bob notes that painting with a brush allows for good coverage up and under each of the clapboards.

Bob reviews some of the work done on the house so far. The house was built in 1921 and the exterior stucco walls are in good shape overall. The woodwork, however, was in bad shape as it is 80 year-old wood combined with New England winters. Most of the wood trim was repaired using western red cedar. The gutters on the gambrel roof were also replaced. The porch columns were repaired after suffering insect damage. These stone columns were filled with concrete by mason Kevin Latham. Some new stucco was added where the back door was removed and replaced with a new slider and small window. To add this stucco wall, wire lath is placed over felt paper and plywood. Then a brown coat is added and allowed to cure before the finish coat goes on. Fergus Cullen of CertaPro Painters reviews the issues involved with painting the house. Different parts of the home's exterior are older than others. The old stucco is in good shape, while the new stucco needs to be primed and painted using a couple of coats. The window uses a couple of different materials. The frame has been replaced with Azek, which does not need to be painted but will be painted to match the rest of the trim. The Azek is especially effective in areas where there is a lot of moisture and rot may be a problem. The natural wood surrounding the window will also be primed and painted to match everything else. In some areas the old paint is peeling off in sheets and "alligatoring" or creating check marks in the paint. The old paint used in these sections is likely lead paint and does not have the flexibility New England winter and summer temperature fluctuations. All the areas with chipping and peeling paint will be scraped down, the edges sanded, and then primed. When complete, the texture will be retained but there will be no chipping or peeling involved. Some shingles on the lip of the roof have sustained significant water damage. The damaged shingles are replaced and painted with a solid color stain. This stain looks like paint but penetrates into the wood. There will be a little difference in texture between the old shingles and the new, which comes with having an older home. The most important thing to remember when painting at the end of the season is overnight temperatures. Painting is possible as long as the overnight temperatures are above 35 degrees Fahrenheit. The paint must be given time to cure at the proper temperatures. Painting is also not possible during times of high humidity, which is a problem that plagues hot, humid climates in the South.

Bob joins Ron Boyajian and the painters for the prep work and painting of this 100 year-old wooden Victorian. The painter explains that they power wash the surface with a 50/50 mix of bleach and water to blast away loose paint and kill any mildew. He then shows how to feather the edges of the paint with a sander for a smooth finish. A drop cloth, and a catch on the sander keep chips out of the soil, but it's critical to check for lead content in the paint before disturbing it. Boyajian shows Bob the moisture meter used to check the moisture content in the wood and verify the right type of paint to use on the surface. At around 10 percent moisture, a latex paint will adhere without peeling, but at 25 percent, oil-based paint will peel, so it's important to get an average for the house. Boyajian gives Bob the basics on priming before painting. At 60 percent bare wood, he says it's best to prime the entire house. California Paints uses their Trouble-Shooter linseed-oil-based primer to hold back the tannic acid in the new cedar clapboards so that they won't bleed into the new paint. The painter shows the proper technique for covering clapboards, using a hand-brushing technique to cover the butts first and then the face of the clapboards for good coverage. This primer is tinted to half the depth of the color of the finish coat so that it will hide any imperfections in the top coat.

Bob watches decorator B. Smith paint a lavender stripe pattern in the girl's bedroom of the Habitat for Humanity project.

Bob is joined by Joann Borges of CertaPro Painters, who goes over techniques and selected paints for covering new walls and trim efficiently and evenly. They begin with the paint sprayer that is typically used throughout a new production home. The sprayer begins with the ceilings and works down the walls, staying ten to twelve inches away from the surface to give an even coat. Sprayers cover all surfaces, including doors, closets, and trim to finish a room quickly. Speed and efficiency keep the cost down. High-quality, long-lasting paints mean that homeowners will wait longer to repaint and get more value from their investment. CertaPro is using Sherwin Williams' Duration Home throughout the interiors of these affordable homes. Duration Home is a latex paint that is enhanced with acrylic polymers to give durability and washability in a flat or non-glossy paint. Borges also shows how the painters use rollers to cover walls quickly, cutting in with a 2�-inch angled brush before rolling with an 18-inch roller to speed up the process.
