4 Easy Steps For Painting A Pressure Treated Wood
STEP 1: Thoroughly Clean the Pressure-treated wood
Before you start the paint job, you should wash away any dirt or debris that is on the wood. You need to perform this using soap + water and scrubbing every inch of the lumber by using a rag.
Further, rinse the soap off the pressure-treated wood and dry it using a clean dry rag.
If the wood is not in a proper shape and requires a deeper clean then using a power washer or a commercial wood cleaner will be perfect for the job. This is usually done for the pressure-treated lumber that has been sitting for a long time showing signs of wear and damage.
STEP 2: Let it Dry and Assess the Moisture
The drying time may be stretched out for a couple of weeks or a few months between the chemical usages for treating the lumber. Now, how will you know when the wood feels ready? Just sprinkle some water when the wood feels dry to touch.
In case the water soaks in, then stay assured that the wood can be painted. Start the waiting game again if the water still beads up. If you have a time sensitive project on the cards then you should select pressure-treated wood. After treatment this should be marked as having been kiln-dried after treatment (KDAT).
The timing for painting KDAT wood is significantly is shorter.
STEP 3: Prime & Cure
Once you have the confirmation that your wood is dry, then you can start painting pressure-treated wood.
For exteriors you can begin with primer formulations and ensure that the manufacturer lists that the coating is ideal for pressure-treated wood.
A paint sprayer may be the easiest for priming or painting pressure-treated wood. If the job necessitates detailed work then opt for a brush instead.
STEP 4: Apply 2 coats of paint
After priming and allocation of adequate drying time, you should apple 2 top coats. Expectedly you should go for 2 coats, but remember to avoid using oil-based paint here for your pressure-treated lumber. Latex offers a much better performance
The finish of any outdoor applications is subject to various elements. It’s obvious that the paint lasts longer on vertical surfaces (fences) rather than horizontal surfaces (decks).
If repainting is something you do not appreciate then consider staining your pressure-treated wood (check out for details below).
Another option you have here is to let the wood weather away and turn gray and then use a protective sealant instead. Even sealant also needs to be reapplied with time. Many people consider all this less demanding than repainting but this leads to scraping away of the parts.
Staining VS Painting Pressure Treated Wood
As mentioned above also, you can choose between staining and painting pressure-treated wood. This can be done after primer cure. But both these options come with a set of positives and negatives.
1. Staining the Wood
For changing the color of your wood you can use a stain. This is easy to apply and penetrates deep inside the wood.
But note this is not going to fill any imperfections or cracks like the paint does. Even the color options at your disposal will be less too as these offer more shades of brown.
2. Painting the Wood
Pressure-treated wood can be painted with vibrant new colors adding new life to it. With loads of color options and much brighter colors unlike stain, the paints can be used for your lumber.
Some people do ask, can one paint over exterior stain? We have answered thus below in our FAQs section.
The paints tend to fill any sort of imperfections and cracks too giving your wood a smoother appearance. But the paints do not soak well and take slightly longer to finish.
