Its spark shield keeps you safe from flying concrete bits. When you need extra power, the 2000w output tackles even the toughest concrete surfaces.
Scenario 2: Removing Old Paint or Coatings from Patio Floors
First, test the old coating to see if it contains lead. If it does, call a professional. If it's safe, Use a wire cup brush attachment on your cordless angle grinder. Start at one corner of the patio. Work in straight lines. Keep the grinder moving steadily. Don’t stay too long in one spot; instead, ensure the coating comes off in strips. Vacuum or sweep away the debris often. Some tough spots might need several passes. After you have removed all coating, thoroughly clean the surface.
Scenario 3: Grinding Down Uneven Patio Slabs
Mark the high spots with chalk, then proceed to grind them down. Put on your safety gear. Use a diamond cup wheel attachment. Start at the highest point. Work outward in a circular motion. Check your progress often with a level. Go slowly to avoid grinding too deep. Clean away dust between passes. Test the surface with a long level across multiple slabs. Keep grinding until all slabs are even. Finish by smoothing any rough spots.
Scenario 4: Shaping and Resizing Pavers for Patio Design
Set up a stable work surface like a sturdy table. Mark your cutting lines clearly with a pencil. Use a diamond blade designed for masonry. Secure the paver firmly. Start the cut slowly to create a groove. Then, make steady passes through the paver. Don't force the blade. Allow it to cut at an optimal pace. Cool the blade with water if you notice it becoming overheated or discolored. After cutting, smooth any rough edges. Test fit the paver before cutting more.
Scenario 5: Cleaning Rust from Metal Patio Furniture
Start with a wire brush attachment. Put on safety glasses and gloves. First, remove loose rust by hand. Hold the grinder at a slight angle against the rusty surface. Move in one direction only. Don't press too hard. Change spots often to avoid damaging the metal. Clean small areas at a time. Wipe the surface clean to check your progress. Use finer attachments for finishing.
