When it comes to interior painting, there's a saying among professional painters: "Preparation is 80% of the job." At Painters Kingston, we've seen firsthand how proper prep work makes the difference between a mediocre paint job that needs redoing in a year and a flawless finish that lasts for years. Yet preparation is often the step homeowners are most tempted to rush through or skip entirely.
In this article, we'll explain why preparation matters so much, what proper prep work entails, and how it affects the longevity and appearance of your paint job, especially in Kingston's unique climate conditions.
Why Preparation Matters
The Foundation of Quality
Think of paint preparation like the foundation of a house. You can use the most expensive paint available, but if it's applied over dirty, damaged, or improperly prepared surfaces, the results will be disappointing. Paint adheres best to clean, smooth, properly primed surfaces. Without this foundation, even premium paint will fail prematurely.
Long-Term Cost Savings
While thorough preparation takes time and adds to the initial cost of a painting project, it saves money in the long run. A properly prepared and painted surface can last 7-10 years, while a poorly prepared one might need repainting within 1-2 years. The math is simple: investing in proper prep work now means fewer repaints later.
Professional Results
The difference between an amateur-looking paint job and a professional finish often comes down to preparation. Proper prep work eliminates bumps, ridges, visible patches, and uneven color absorption that can make even expensive paint look unprofessional.
Essential Preparation Steps
1. Thorough Cleaning
All surfaces must be completely clean before painting. This means removing:
- Dust and dirt - which prevent proper adhesion
- Grease and oils - particularly important in kitchens
- Mildew and mold - common in Kingston's humid climate
- Smoke residue - which can bleed through new paint
Professional Approach: We use specialized cleaning solutions depending on the contaminants present. For example, TSP (trisodium phosphate) for grease, or mildew-specific cleaners for bathroom areas. Simple soap and water isn't always sufficient for proper paint preparation.
2. Surface Repairs
Any damaged areas must be repaired before painting:
- Drywall damage - holes, dents, and cracks need proper patching
- Wood repairs - rotted or damaged wood should be replaced or restored
- Caulking - gaps around trim, windows, and doors need fresh caulking
- Loose materials - any peeling paint or wallpaper must be removed
Professional Approach: Different surfaces require different repair materials. We select appropriate fillers and patching compounds based on the surface material and the extent of damage. For example, lightweight spackle works for small nail holes, while deeper damage might require multiple applications of joint compound.
3. Sanding
Sanding serves multiple crucial purposes:
- Creates a slightly rough surface that helps paint adhere better
- Smooths out repaired areas so they blend seamlessly
- Removes any remaining loose paint or debris
- Feathers edges between old and new surfaces
Professional Approach: We use different grit sandpapers for different stages of preparation. Coarser grits (80-100) for initial smoothing of patches and repairs, medium grits (120-150) for general surface preparation, and finer grits (180-220) for final smoothing before primer application.
4. Priming
Primer is not just an extra coat of paint. It serves specific functions:
- Seals porous surfaces to prevent uneven paint absorption
- Blocks stains from bleeding through (water stains, smoke, crayon, etc.)
- Provides better adhesion for the topcoat
- Creates a uniform base for consistent color appearance
Professional Approach: We select primers specifically for the surface and conditions. For example:
- Shellac-based primers for severe stains or water damage
- Oil-based primers for bare wood or when covering oil-based paint
- Specialized bonding primers for glossy or difficult-to-paint surfaces
- Drywall primers for new drywall or after major repairs
5. Protection and Masking
Proper preparation includes protecting areas that shouldn't be painted:
- Covering furniture and floors with drop cloths
- Taping off trim, windows, and fixtures
- Removing hardware, switch plates, and outlet covers
- Protecting adjacent surfaces from overspray or splatter
Professional Approach: We use different types of protective materials depending on the situation. Canvas drop cloths for floors (they stay in place better than plastic), specialized painter's tape for clean lines, and plastic sheeting for larger areas needing protection.
Kingston-Specific Considerations
Humidity and Moisture Issues
Kingston's proximity to Lake Ontario means we deal with higher humidity levels than many other areas. This creates specific preparation challenges:
- More thorough mildew remediation is often necessary
- Moisture meters may be used to ensure walls are truly dry before painting
- Additional drying time between preparation steps may be required
- Specialized moisture-resistant primers might be recommended
Seasonal Considerations
Kingston's distinct seasons affect interior painting preparation:
- Winter: Heating systems create very dry air, which can cause faster drying times and potential shrinkage of patching compounds
- Summer: High humidity can extend drying times for repairs and primers
- Spring/Fall: Temperature fluctuations can affect how materials cure and dry
We adjust our preparation techniques and materials based on the season to ensure optimal results.
Historic Home Considerations
Kingston has many historic homes that require specialized preparation approaches:
- Testing for lead paint in homes built before 1978
- Special techniques for plaster walls and ornate trim
- Careful preservation of historic details
- Addressing issues common in older homes like settling cracks and previous repairs
Common Preparation Mistakes
Rushing the Process
The most common mistake is simply not allowing enough time for proper preparation. Each step needs adequate time:
- Patching compounds need to dry completely before sanding
- Primer needs to cure properly before topcoat application
- Cleaned surfaces need time to dry thoroughly
Rushing these steps leads to problems that will be visible in the finished product.
Inadequate Cleaning
Simply wiping surfaces with a damp cloth isn't sufficient. Proper degreasing agents and appropriate cleaning methods are necessary, especially in kitchens and bathrooms.
Improper Sanding
Many DIYers either skip sanding entirely or don't sand sufficiently between coats. This leads to visible imperfections and potential adhesion problems.
Skipping Primer
Modern "paint and primer in one" products have led many to skip dedicated primer. While these products work well for maintenance painting on previously painted surfaces in good condition, they're not a substitute for proper primer in many situations.
When to Call Professionals
While some painting projects are suitable for DIY, certain preparation scenarios benefit greatly from professional expertise:
- Extensive repairs - When walls have significant damage or multiple layers of old paint
- Water damage - Which may indicate underlying issues that need addressing
- Older homes - Especially those that might contain lead paint
- Mold or mildew problems - Which can indicate moisture issues requiring expert assessment
- Specialty finishes - Which require specific preparation techniques
