Sanding leveling compound involves using a combination of techniques to achieve a smooth, even surface after the compound has dried.
Initial Leveling
The first step in preparing the leveling compound for sanding is to ensure you achieve the best result while the material is still wet:
- Use a Trowel: As you apply the leveling compound, use a trowel to level the compound as much as possible while it is still wet and pliable. This initial step will minimize the amount of sanding needed later.
- Apply in Small Amounts: Avoid applying large amounts at once. Small amounts help prevent the compound from drying before you have a chance to level it correctly.
Sanding Dried Leveling Compound
Once the leveling compound has dried, sanding is often necessary. Here’s how to do it effectively:
For Bumps and Uneven Areas
- Grinder: A grinder is most useful for sanding down larger bumps and areas of uneven dried leveling compound.
- Electric Sander: For smaller bumps or to refine a surface, an electric sander with coarse sandpaper works well.
Table Summary of Sanding Techniques
| Issue | Tool | Technique |
|---|---|---|
| Large Bumps | Grinder | Grind down the high spots |
| Small Bumps | Electric Sander | Use coarse sandpaper to smooth uneven patches |
| General Smoothing | Electric Sander | Progress to finer sandpaper |
Step-by-step Approach to Sanding
- Assess: Carefully examine the dried leveling compound to identify all bumps, ridges, and uneven sections.
- Grind: Start with a grinder if large bumps are present and grind them down to the level of the surrounding areas.
- Sand: For minor imperfections, use an electric sander with coarse sandpaper to smooth out the area.
- Refine: If needed, switch to a finer sandpaper to achieve an even smoother finish.
By taking the time to initially level with a trowel and then methodically sanding after drying, you can achieve a smooth and even surface with leveling compound.
