Applying an exterior paint sealant is one of the best ways to protect your home’s exterior from harsh weather, UV rays, and other elements. By creating a protective barrier, a quality sealant helps maintain the vibrant color of your paint and extends the lifespan of your exterior surfaces. In this guide Gas Cap, we'll walk you through each step to make your home look fresh and resilient against the elements.



Why Use Exterior Paint Sealant?


Using an exterior paint sealant has several benefits, from preserving the color and appearance of your paint to adding a layer of defense against dirt, moisture, and mildew. A good sealant works with your exterior home pressure washing routine to ensure that your home’s exterior looks its best year-round.



Materials You Will Need



  • Exterior paint sealant (high-quality, weather-resistant)

  • Pressure washer for exterior wash

  • Soft-bristle brush or roller

  • Paint sprayer (optional for large surfaces)

  • Masking tape and plastic sheeting

  • Ladder

  • Safety goggles and gloves





Step 1: Prepare the Exterior Surface


Before applying a sealant, it’s crucial to start with a clean surface. A thorough exterior home pressure washing removes dirt, mildew, and loose paint, ensuring that the sealant adheres properly. Here’s what to do:

  • Use a Pressure Washer: Begin by pressure washing the entire exterior surface. Make sure to get into all nooks and crannies, especially near exterior windows and door frames.

  • Fence Cleaning and Exterior Details: If you have fences or other exterior woodwork, clean these areas thoroughly as well.

  • Let it Dry: Allow the surface to dry completely. Any remaining moisture can compromise the effectiveness of the sealant.





Step 2: Mask Off Windows and Other Surfaces


Using masking tape and plastic sheeting, protect areas like exterior windows, doors, and other fixtures you don’t want to get sealant on. Be sure to cover surfaces like the front bumper of any nearby vehicles and outdoor decor that may be affected.



Step 3: Choose the Right Sealant Application Tool


Selecting the right application tool will depend on the size and surface of your home. Here are your main options:

  • Paint Sprayer: Best for large surfaces, like walls, as it provides even coverage and reduces application time.

  • Roller or Brush: Ideal for smaller or intricate areas, such as trim, eaves, and gas cap areas near doors or openings.





Step 4: Apply the Exterior Paint Sealant


Once you’ve prepped the surface and selected your application tool, it’s time to apply the exterior paint sealant:

  • Start from the Top: Begin at the top of your house and work your way down. This ensures that any drips won’t ruin already-coated areas.

  • Apply Evenly: Use smooth, overlapping strokes to ensure even coverage.

  • Use Extra Care on High-Traffic Areas: Areas that get a lot of wear, such as near floor mats at entrances, door frames, or places close to the front bumper of vehicles parked near the home, may require an extra coat for added durability.





Step 5: Allow the Sealant to Cure


After applying the sealant, allow it to cure fully. Curing times will vary depending on the sealant, but most require at least 24 hours to dry completely. During this time, avoid touching or washing the surface, and keep the area free of dirt and debris.



Step 6: Final Touches and Maintenance


Once the sealant is dry, remove the masking tape and plastic sheeting carefully. Your home is now protected and ready to withstand the elements. For continued maintenance:

  • Exterior Wash and Rinsing: Perform a light rinse of your home’s exterior periodically to keep it looking fresh.

  • Interior & Exterior Cleaning: Consider setting up a schedule for both interior basic and exterior cleaning to keep your whole home in top condition.

  • Regular Inspections: Inspect areas like exterior windows, fences, and high-traffic zones annually to assess if you need touch-ups or reapplications.





Tips for Prolonging the Sealant’s Lifespan



  • Avoid Harsh Cleaners: Use gentle cleaners to avoid stripping the sealant.

  • Keep High-Traffic Areas Clean: Regular floor mats shampoo and other routine maintenance will help preserve your sealant.

  • Routine Fence Cleaning: Protect wood fencing by applying sealant here as well and washing it periodically to extend its life.
