How do you handle peeling paint on weathered cedar siding?

We use fiber disk sanding to rip off loose paint and remove the top layer of gray, weathered wood fibers. This exposes fresh wood ready for oil-based primer penetration.

Why is oil-based primer necessary for PNW homes?

Oil-based primer, like Zinsser, replenishes moisture in dry cedar and balances the substrate PH. We roll it on to force the primer into microscopic moisture pockets common in the high-humidity Eastside climate.

Day 1: Preparation & Substrate Restoration

As always, we started by tackling the most challenging and time-consuming portions of the project. On this house, we focused on the south side (chimney side) and the front. This is where the PNW weather beats down on the siding, leaving it in poor shape. We began by masking windows and fencing before moving on to sanding and primer.

Expert Insight: Restoration vs. Painting

Our Solution: Fiber disk sanding. Unlike standard sanding, a fiber disk rips off loose paint and removes approximately 1/32" of weathered wood. This exposes fresh cedar ready for maximum primer adhesion.

Advanced Priming & Sealing

All sanded areas are primed with Zinsser exterior oil-based primer. This "mother of all primers" penetrates the wood to become one with it, replenishing essential moisture and balancing the PH of the substrate. In the high-humidity environments of Redmond and Bellevue, we force the primer into the surface with rollers to seal out moisture.

Critical Detail: Verge Boards & Chimneys

Moisture often causes paint failure at the ends of verge boards and chimneys. We treat these areas with specialized care to ensure they age at the same rate as the rest of the house, preventing that "weathered" look on the home's exposed side.

Application & Finishing

For this project, we applied two coats of Benjamin Moore MoorGlo. Siding was back-rolled to force material into the grain, while trim was hand-painted with two coats for a premium finish.

Pacific Northwest Exterior Trends & Performance

In the Pacific Northwest, lighting is everything. Under our typical overcast skies, colors like Benjamin Moore Texas Leather AC-31 provide a warm, grounding presence that doesn't wash out. For Exterior Paint Trends 2026, we are seeing a shift toward earthy neutrals that mimic the natural PNW landscape.

Overcast Conditions: We recommend colors with slightly higher LRVs (Light Reflectance Values) to maintain brightness on gray days.
Wood Preservation: Our use of oil-based primers is specifically designed to combat the "freeze-thaw" cycles common in Issaquah and Sammamish.
Product Choice: We utilize high-resin coatings like Benjamin Moore MoorGlo to provide the flexibility needed for cedar expansion in high-humidity areas like Cottage Lake and Woodinville.
