📚 Application Tips
Painting Tips
Use a roller for large flat areas and brushes for edges. Multiple thin coats are better than one thick coat.
Watering Guide
Most plants need about 1 inch of water per week. Adjust based on soil type and weather conditions.
Cleaning Solutions
Always test cleaning solutions on a small area first. More concentrated doesn't always mean more effective.
Measure Accurately
Always measure your area and calculate needed materials to avoid waste or shortage.
Safety First
Wear appropriate protective gear when working with chemicals or paints.
Mix Thoroughly
Always mix paints and solutions completely for consistent coverage and results.
