Is It Okay To Keep The Outside Pvc Trim Unpainted?

PVC trim can be left unpainted or painted, depending on the specific needs of the project. Extruded Cellular PVC can be left unpainted, but it is important to consider the potential risks associated with aging and peeling paint. Painting PVC trim is different from other materials, as it adheres better to cellular PVC due to its 6 moisture allowance.

To avoid peeling paint, many homeowners choose to leave their PVC trim in its natural white state. When nailed or screwed into place, nail holes are usually covered over with vinyl spackle to give the boards a smooth appearance. However, once painted, the PVC trim will need to be kept up, as paint peals will be necessary for the entire job. If not painted, it will mildew.

Unpainted PVC trim can be easily cleaned by using denatured alcohol and acetone, but it may not be suitable for milling PVC trim. AZEC states that its PVC trim does not need paint, but it accepts and holds paint well. It is crucial to choose the right paint for the job and consider the aesthetic options available for PVC trim.

Unpainted PVC trim is naturally low-maintenance, resistant to dents, scratches, and splitting, and does not require painting but lacks the customizable aesthetic options of painted trim. To finish cut ends and pieces, touch sand and use the best products to paint them.

How do you seal PVC trim edges?

The use of 120-320 grit sandpaper and clear adhesive or acetone to sand the cut edge of PVC trim can effectively seal it to a factory finish, making this an efficient and straightforward method. To enhance the efficacy of the application process, it is recommended to utilize acetone in a roller marker or felt applicator.

Can you leave PVC outside?

PVC piping is susceptible to degradation due to direct sunlight exposure. The molecular structure of PVC is easily damaged and prone to shattering. To protect PVC pipes, it is recommended to paint or conceal any visible pipes, and to buy from a company that keeps its inventory covered. This will not only prevent fading in the sun but also prolong the pipes’ lifespan. Improper installation and use can lead to piping system failure, as PVC cement is used to bond pipes to fittings. One common error in installing PVC piping systems is applying too much or too little PVC cement. Therefore, it is crucial to ensure proper preparation and use to prevent PVC piping failures.

Do you have to paint azek trim?

AZEK Trim products are not inherently painted for protection; however, they can be painted for the purpose of achieving a custom color or filling nail holes. Nevertheless, PaintPro Trim must be painted within 180 days of exposure to ultraviolet radiation from the outdoor environment.

Is PVC exterior trim better than wood?

PVC is a durable, water and rot-resistant material that resists elements and bugs, making it a cost-effective alternative to wood. It doesn’t require prior treatment and can be painted or stained, making it suitable for homeowners on a tighter budget. PVC is also resistant to bugs and pests that can take up residence inside wood. Its AZEK Trim with PaintPro technology offers a clean, crisp look, making it a popular choice for homeowners.

Does PVC trim warp in the sun?

PVC trim can expand or shrink when exposed to hot weather, causing issues with bonding and peeling paint. Dark colors are not suitable for PVC trim due to their noticeable cracks over time. PVC is not an eco-friendly material as it is made from a type of plastic that emits harmful VOCs during manufacturing and installation. Recycling is not possible, and most recycling plants do not receive it. PVC trim is often left in its natural white state to avoid peeling paint, and nail holes are covered with vinyl spackle to give the boards a smooth appearance. Despite these drawbacks, PVC trim is a durable and eco-friendly option for homeowners.

Can you leave PVC trim unpainted?

While PVC trim can be left unpainted, it may exhibit visible signs of dirt or deformation when exposed to direct sunlight. Consequently, it may be regarded as an optional material for certain PVC types, such as extruded cellular PVC.

Does PVC exterior trim need to be painted?

Painting cellular PVC trim is a unique process due to its superior adhesion to paint compared to wood. Wood has a moisture allowance of 6 and requires repainting after three to five years, while cellular PVC can last up to 25 years if the right paint is chosen and the PVC is properly prepared. Most coatings are dry within an hour or less, but may take 30 days to fully cure depending on humidity and temperature. To prepare the trim, clean it thoroughly, lightly scuff the surface, and use a premium 100 acrylic latex paint with a built-in primer.

If required under the paint manufacturer’s warranty, follow the same LRV limitations. Painting after installation can help avoid repetitive touch-ups and allow installers to proceed with the job before the homeowner decides on a color.

How long will PVC trim last outside?

Fully Cellular PVC is a wood trim replacement that mimics the appearance of wood but doesn’t absorb moisture. It can be cut and shaped like wood but doesn’t need to be repainted every four to five years. Wood trim is popular due to its low cost and durability. However, wood absorbs moisture more than wood, leading to irreversible damage. To prevent this, homeowners can choose to cap wood trim with aluminum coil wrap or replace it entirely with cellular PVC. The cost of Fully Cellular PVC is $24-28 per linear foot and has a lifespan of 30-50 years, depending on the manufacturer.

What is the downside of PVC trim?

Cellular PVC trim is popular among builders due to its lightweight, durable, and waterproof properties. However, it does not move due to moisture like wood, but rather due to temperature. PVC trim grows and shrinks along its length, which can cause noticeable shrinkage and break glue joints. If installed in mild weather, it may shrink when cold and expand when hot, but gaps can open up when temperatures drop to zero in January. To prevent this, use planned movement joints to ensure movement occurs where it should occur.

Nail the trim securely to a solid substrate in visible locations, glue the joints that need to be kept closed, and provide unglued movement joints in less noticeable spots, such as masked behind a corner board.

Does PVC need to be painted?

PVC, or polyvinyl chloride, is not all that needs to be painted. Extruded Cellular PVC, for example, is created with sealed pores that make it difficult for paint to adhere to the material. While it is possible to paint PVC, there are some restrictions and considerations to keep in mind. For example, the pores of Extruded Cellular PVC are not visible externally, making it unpainted and having no effect on the product. Therefore, while PVC can be painted, it is not designed to be a durable material.

Does PVC trim need to be primed?

To prepare exterior PVC trim, remove the trim, wash it with soapy water, and allow it to dry. Scour the surface with sandpaper to create a perfect surface for primer application. Brush on a PVC paint primer that accepts a latex coat, which can be found at paint stores, hardware stores, or online sources. Allow the primer to dry before applying the latex paint. If the trim cannot be removed, mask the surrounding area before painting.

Apply the latex-paint top coat, then apply a second coating once the first one is dry. The necessary tools include soapy water, masking tape, PVC spray paint, latex paint, a pry bar, 400-grit sandpaper, paintbrush, vinyl primer, and a work table or bench.
