Should I Clean The Exterior Trim Before Painting It Again?

Preparing exterior trim before painting is crucial for a high-quality paint job. Cleaning and repairing it prior to painting ensures that the paint doesn’t cover dust, dirt, and other debris, making the paint go on smooth and lasting longer. This often requires extensive scraping and sanding of existing siding and trim.

To begin, wash the surfaces using a hose and a scrub brush. Wash the trim from the bottom upward with slow, easy up-and-down strokes to soften the grime. Use a TSP solution or a low-phosphate household cleaner to clean the surface of the trim. Rinse thoroughly with a vinegar/water solution and let the trim dry. Use a stiff putty knife to scrape away loose paint.

Ensure you have the right painting supplies. Start by scrubbing off all dirt and chalking paint with a scrub brush and a solution of trisodium phosphate (TSP). Rinse the trim thoroughly and allow it to dry. Wet your walls before scrubbing them and then wash them with a mixture of 1 gallon of water, 1 cup of chlorine bleach, and 1 cup of either a concentrated phosphate.

The difference between pressure washing and soft washing is that pressure washing requires high pressure but uses less soap, detergent, and water, while soft washing works best on delicate surfaces like wood and vinyl siding. Therefore, it is recommended to pressure wash before painting and use a soft wash to maintain the paint.

Preparing the surface is crucial for a long-lasting paint job, as painting over dirty siding can cause premature peeling. If the surface still has contamination, oxidation, or dirt, the paint will not adhere properly, leading to cracking and peeling over time. The lifespan of exterior paint in Ohio ranges from five to twenty years, depending on the substrate. Wood siding lasts for five years, while aluminum and vinyl last up to twenty. Regular soft washing will protect the paint and help it last longer.

Power washing is not recommended for freshly painted houses, as it can cause paint bubbles, cracks, or peel. Instead, the soft wash approach is the safest, easiest, and most effective way to keep your house clean.
