When you sand cedar wood, for better results, use the following grit:
1. Preliminary grinding: Use a coarse grit, such as 80-100 purpose sandpaper or emery cloth, to remove the rough part of the surface of the cedar wood and the bark.
2. Intermediate grinding: Use a medium grit, such as 150-220 grit sandpaper or emery cloth, to further smooth the surface and prepare it for painting or dyeing.
3. Detailed grinding: Use finer grit, such as 320-600 purpose sandpaper or emery cloth, to remove the marks left during the grinding process and make the surface more smooth.
There may be several reasons for poor dyeing results:
1. Insufficient cleaning before dyeing: Ensure that dust and grease are removed from the surface before dyeing to obtain better dyeing results.
2. Quality of the dye: Use high-quality, easy to mix and uniform coverage of the dye, in order to obtain a consistent dyeing effect.
3. Dyeing method: Try to use a brush, sponge or cloth for dyeing to reduce unnecessary marks.
4. Environmental factors: light, temperature and humidity may affect the dyeing effect. Dyeing in a suitable environment can improve the effect.
5. Practical experience: try different methods and skills, accumulate experience, and gradually improve the dyeing effect.
