To prepare exterior woodwork for paint, cover openings with plastic, thoroughly wash the wood, and patch holes with wood filler. To prepare wood for paint, scrape off flaking paint, treat knots with specialized primers, sand the entire surface, and wipe the surface clean.

To prepare painted woodwork for repainting, remove dust, dirt, and grime from the surface. Follow a step-by-step guide to thoroughly clean the woodwork surface to ensure that your new paint adheres. For exterior projects, remove and replace caulking around windows, doors, vents, etc. For interior projects, use caulking to protect outdoor paintwork from cold, damp periods.
The type of paint used depends on the type of paint you’re using. Some water-based wood preservatives can leave a thin skin on the wood surface, which may be difficult to remove. Clean the wood surface thoroughly using a long-handled scrubber brush and a mild detergent. A safe option is using a specific wood cleaner such as Net-Trol, which is a strong yet gentle water-based cleaner.
Regularly inspect the painted wood for signs of damage, such as peeling or cracking, and clean the surface annually using a mild detergent and a soft brush. Wood usually needs at least lightly sanded for best results, with areas where the condition is worse requiring scraping and priming. Scrub off old paints with a scrubbing brush, water, and detergent, then smooth any sharp edges with sandpaper. Remove dust, dirt, or grease with a damp cloth to prevent interference with a successful finish when painting.
A mixture of bleach and water is generally effective for exterior woodwork, with one-part bleach to every three-parts water. If mildew is present, use bleach. Bleach water is the go-to cleaner for exteriors, and TSP is added if extra grime needs to be cleaned off.

What is the best solvent to clean wood before painting?
Before painting, it is essential to clean down cabinetry in the kitchen, bath, or laundry room. First, clean with Mineral Spirits, then rinse it with clean fresh water. For older towels or t-shirts, apply a small amount of odorless mineral spirits on them and wipe down the piece. This process is recommended for any painting occasion, as it helps to remove dirt and debris from the surface. It is also important to allow the Mineral Spirits to completely evaporate before painting. This process ensures that the piece is ready for the next painting application.
Do you have to sand outdoor wood before painting?
When painting a new wood surface, it is important to consider the adhesion of paint and stain to the surface. A rough-sawn surface can take longer to adhere to paint and stain than a planed, smooth surface. To ensure good results, use 80-120 grit sandpaper and lightly sand the surface before painting smooth siding. Clean the wood surface thoroughly, as applying paint to a dirty, wet, chalky, or degraded substrate can prematurely fail the paint job.
A power wash with detergent and diluted chlorine bleach or a scrub brush with a detergent solution like trisodium phosphate (TSP) can be used for cleaning. If the surface still has chalky color after cleaning, it is not ready for painting. Additions like Emulsa-Bond can help the paint bind to a slightly chalky surface and provide an inexpensive insurance policy. It is crucial to follow the instructions provided by the store staff and follow the instructions to ensure a smooth and successful painting process.
