Preservative-treated barge boards require a unique set of considerations when painting. Many homeowners struggle with common issues like uneven surfaces and adhesion-related concerns. Moreover, myths say achieving a flawless finish on a board roof is an impossible task. With the right techniques, product selection, and a little know-how, you can turn this stressful project into a rewarding one.
We will address these concerns head-on in this blog.
Why Are Barge Boards Treated With Preservatives?
Preservative-treated trim and barge boards, mainly used outdoors, are treated with chemicals to resist decay and insects. This extends their lifespan. However, this treatment, while beneficial, poses challenges for finishing.
The introduced chemicals alter the wood’s composition, affecting its ability to absorb conventional finishes like paint or stain. This alteration may lead to difficulties in achieving a perfect finish on your barge boards, including uneven absorption and adhesion issues.
In this regard, considerations for treatment compatibility are crucial. Using incompatible products can result in peeling or uneven appearances. To overcome these challenges, it’s vital to choose finishes specifically designed for preservative-treated wood, ensuring a durable and attractive outcome.
Tip #1: Ensure Proper Surface Preparation For A Better Finish
First things first, ensure the vergeboard is clean and smooth before applying any finish. Wipe away any dirt or contaminants, and smooth out any rough patches with medium-grit (60 to 80 grit) sandpaper. This step prepares the surface for a finish that sticks well to the wood surface, giving it a polished look.
Tip #2: Choose The Right Exterior Finish So That It Lasts Longer
Choose an exterior finish that is as durable as the treated Hardie board and batten. Remember, you are using it on the roof, a surface most exposed to the elements. Make sure the paint or stain you use can withstand the outdoor conditions of your region!
Look for features such as UV protection to protect against the sun’s rays. Find UV-resistant trims from reliable suppliers for added security. Belco Forest Products stresses to check whether your exterior finish provides resistance to moisture and mildew for a long-lasting finish.
Tip #3: Always Apply A Wood Primer For Better Adhesion
Using an exterior wood primer is an important step in the process. This primer improves the finish’s adhesion to the treated wood surface, resulting in a smoother and more durable coating. You can also look for a pre-primed barge board from reliable suppliers. It is critical to ensure that the primer is compatible with both the preservative treatment and your chosen finish.
Tip #4: Multiple Thin Coats Are Better Than a Single Thick Coat
Instead of a single, thick coat, try layering while painting the roof rake board. Multiple thin coats provide better coverage, penetration into the wood, and adhesion. Following the drying times recommended by the product manufacturer between each coat ensures optimal results. This way, the corner board on the house gets a more professional finish.
In terms of the technical specifics of paint application, two coats are often necessary to achieve the correct thickness. For exterior projects, this is true for detailed work like one wants to achieve while trimming. The first coat usually does not suffice in achieving the desired color or sheen. The second coat helps in building up the thickness and uniformity of the paint layer.
Tip #5: Consider Using A Sealant Or Topcoat For Added Protection
After you have applied the finish to the roof shadow board, think about its long-term protection. A clear wood sealer or topcoat adds an added protective layer against the elements. This additional layer increases the finish’s durability and resistance to weather conditions. Check that the sealer you choose is compatible with both the finish and the preservative treatment. This will create a protective layer on your exterior trim board.
Tip #6: Make Sure To Provide Ample Drying And Curing Time
Be patient during the drying and curing process after the final coat of finish has been applied. Follow the manufacturer’s instructions for the particular exterior board installation you are using. If you rush through this step, the finish’s durability and overall quality will suffer. Before exposing the barge boards to regular use or adverse weather conditions, make sure they are completely cured.
Tip #7: Regular Maintenance Goes A Long Way
Schedule regular maintenance checks to inspect the condition and finish of the house corner boards. Look for signs of wear, peeling, or discoloration. Take care of any issues as soon as possible by spot-touching or refinishing as needed. Maintaining the trim regularly helps extend the life of the finish. It also ensures your barge boards maintain their flawless appearance in the long term.
The art of achieving a flawless finish on preservative-treated barge boards necessitates planning, appropriate product selection, and listening to experts! You are now prepared to turn your barge board painting project into a rewarding and visually stunning home improvement project. Happy painting!
