Application Tips For Long-lasting Results

Applying the right product delivers a robust defense against weathering, preserving the natural beauty of your cedar surfaces.Cedar wood decks and sidings add timeless beauty to your home. Protecting your cedar with the right sealer extends its life and maintains its rich appearance. For durability and aesthetic appeal, applying sealer correctly is as crucial as choosing the best sealer. Consider these tips and common practices for an impeccable finish that lasts.

Best Practices For Sealer Application

  • Ensure the cedar surface is clean before applying sealer. Dirt and grime hinder adhesion.
  • Sand the wood slightly to allow for better penetration of the sealer.
  • Apply thin, even coats rather than a single thick layer to promote uniform drying and coverage.
  • Use a high-quality brush or roller for application to avoid streaks and ensure a smooth finish.
  • Follow the manufacturer’s instructions for drying times between coats and before using the deck or siding.

Common Mistakes To Avoid

  • Do not apply sealer in direct sunlight or to hot surfaces; this can cause fast drying and uneven application.
  • Avoid applying sealer when rain is forecasted within 24 hours of application.
  • Over-application can lead to a sticky finish and attract dirt.
  • Skipping end grain treatment may result in moisture ingress and wood rot.
  • Ignoring manufacturer’s guidelines may void warranties and reduce the effectiveness of the sealer.

Seasonal And Weather Considerations For Application

Temperature and humidity impact sealer adhesion and drying. Aim for a day with temperatures between 50°F and 90°F and humidity below 85%.

Early fall often presents ideal conditions for sealing cedar. Avoid winter as cold temperatures prevent proper sealer curing.

Time your application to allow the sealer to dry without interference from the elements. Plan ahead for a clear weather window.

A well-maintained cedar wood deck siding not only looks stunning but also lasts longer. Proper maintenance and reapplication of sealer preserves the natural beauty of cedar.

  • Annual Inspection: Look for damage or wear.
  • Cleaning: Gently wash siding yearly.
  • Immediate Repairs: Fix issues to prevent further damage.

Look out for cues that suggest your cedar siding needs a new coat of sealer:

  • Fading Color: UV rays can dull the wood.
  • Moisture Absorption: Water no longer beads up.
  • Surface Roughness: The wood feels less smooth.
