The Right Surface Prep for the Perfect Exterior Finish

Even the best paint requires proper preparation for a flawless finish. Duralex Ultrashield’s performance increases significantly when surfaces are cleaned, repaired, and primed correctly.

Step-by-Step Application Guide

Clean and treat the surface
Remove dust, chalk, grease, or loose paint. Treat any mold or algae with bleach.

Repair defects
Fill cracks and holes, smooth with putty, and sand lightly for a consistent surface.

Apply primer & putty
For new surfaces, use Duralex Exterior Primer and 2–3 coats of Exterior Putty before finishing coats.

Apply Duralex Ultrashield
Use brush, roller, or spray and apply 3–4 coats, allowing 1–2 hours drying between coats.

Why it Matters

Correct preparation ensures:

  • Strong adhesion

  • Longer paint life

  • Uniform finish

  • Maximum weather and water resistance

Using Ultrashield with proper surface prep gives your walls lasting beauty and protection — exactly what every home deserves.
