One of the most common mistakes homeowners make when painting the exterior of their home in Myrtle Beach is skipping the pressure wash. In coastal South Carolina, this isn't optional — it's the difference between a paint job that lasts 8 years and one that starts peeling in 18 months.
Why Coastal Surfaces Are Different
Horry County's combination of salt air, humidity, pollen, algae, and mildew means exterior surfaces accumulate a layer of biological and mineral contamination that you often can't see clearly from the ground. When you paint over that contamination, the paint bonds to the debris rather than the surface itself — and when the debris breaks down, the paint goes with it.
What Happens When You Skip the Pressure Wash
- Paint adhesion fails within 1–3 years — especially in direct sun areas
- Mildew and algae bleed through the new paint coat within months
- Salt deposits cause blistering at the surface interface
- The entire job has to be stripped and redone — far more expensive than doing it right the first time
Every exterior painting job we do at Bakerss starts with a full pressure wash and dry time — usually 24–48 hours depending on conditions — before a single drop of paint touches the surface.
The Right Sequence for Coastal Exterior Painting
- Full exterior pressure wash — house, trim, and any surfaces being painted
- Allow minimum 24 hours dry time (48 hours after heavy wash)
- Scrape any peeling or bubbling paint
- Sand rough areas and spot-prime bare wood
- Caulk all seams, joints, and gaps
- Prime bare surfaces and problem areas
- Apply finish coat — two coats in coastal environments
How Long Should You Wait After Pressure Washing to Paint?
In Myrtle Beach's humid climate, we recommend a minimum of 24 hours after pressure washing before painting. If the wash was heavy or the humidity is high, 48 hours is safer. Painting over a damp surface in coastal SC is one of the fastest ways to guarantee early failure.
Soft Wash vs Hard Pressure Before Painting
For most siding — vinyl, fiber cement, painted wood — soft washing with a cleaning solution is the right choice before painting. High-pressure washing can force water behind siding or raise wood grain in ways that create adhesion problems. Our team adjusts technique based on the surface type.
Need both pressure washing and painting done? Contact Bakerss — we handle both and coordinate the timing so your surface is perfectly prepped when paint goes on.
