- Protect floors and furniture by laying sheets or drop cloths around the surface.
- For paint removal: scrape off any loose paint with a scraper or putty knife. Smooth rough edges with sandpaper.
- For wallpaper: use a scoring tool to puncture the surface, apply a solvent, and peel away with a scraper.
- For extra help, use a steamer or heat gun to loosen layers, and test different methods.
- Work carefully and systematically, ensuring the surface is prepared for treatments.
Repairing Cracks And Holes
For a perfect finish, follow these three steps:
- Assess the damage. Examine the cracks & holes. Note their size & depth.
- Ready the area. Clean with mild detergent & water. Remove loose debris.
- Do the repairs. For small cracks, use high-quality spackling. Fill in with a putty knife. For larger holes, use a joint compound with mesh tape for stability.
Pay attention to detail when repairing. Follow these steps for a great foundation.
Keep the weather in mind. Different temperatures affect drying times. Exterior surfaces need materials that can handle outdoor elements.
Take action to repair cracks & holes quickly. Save time & effort for a beautiful outcome!
