Good preparation gives a new coating a sound surface to bond to. In San Antonio, accumulated dust, sun-damaged coatings and moisture issues can all affect the result. The exact preparation should follow the material, its condition and the selected paint system.
Exterior Preparation Checklist
Clean the Surface
Remove dirt, dust and surface contamination using a method appropriate for the siding or masonry. Pressure washing is not suitable at every pressure or on every surface. Allow the substrate to dry adequately before painting.
Remove Loose Paint and Smooth Rough Edges
Scrape failing paint and sand where appropriate so the new coating is not applied over a loose layer. On older properties, assess possible lead paint before disturbing existing coatings.
Repair Damage and Review Joints
Address damaged trim, siding or stucco and identify the cause of recurring cracks or moisture. Replace failed caulk at appropriate joints without blocking drainage or ventilation openings.
Prime Where Required
Bare material, repairs, stains and difficult existing finishes may need a compatible primer. Follow the manufacturer's instructions for coverage, drying and recoating.
Protect Surrounding Areas
Cover or protect windows, fittings and landscaping as appropriate. Plan access and keep work areas clear.
Interior Preparation Checklist
- Agree on moving furniture and protecting floors and belongings.
- Remove or protect hardware and fittings within the scope.
- Clean dust, grease and other contamination from surfaces.
- Fill holes and repair damaged areas while matching the existing texture.
- Sand or degloss where needed and remove the resulting dust.
- Prime repairs, stains and surfaces that require it.
- Mask or carefully cut in adjacent finishes for clean edges.
Why the Details Matter
A repair that is too smooth for a textured wall, an unsealed patch or dust left on trim can remain visible after painting. Preparation should be completed and checked before the finish coats begin.
