Why PREP ETCH is the Best and Green Choice for Preparing Concrete

MASTERMAX PREP ETCH

When it comes to painting or sealing concrete, proper surface preparation is key to achieving a strong, long-lasting finish. That’s where MASTERMAX PREP ETCH comes in. It’s a safe, effective, and environmentally friendly way to prepare your concrete surfaces for optimal adhesion—without the harsh chemicals found in traditional acid etches.


Why Use PREP ETCH?

  • Safe & Eco-Friendly – Unlike harsh acids, PREP ETCH is non-toxic, low-odour, and safe to use near plants and grass. It won’t harm the environment, making it the perfect choice for sustainable DIY projects.

  • Better Adhesion – Helps roughen the concrete surface, ensuring paint or sealer bonds properly.

  • Low Odour – No strong chemical smells, making it easier and safer to use.

  • Versatile – Works on driveways, garage floors, concrete steps, and pathways.

  • Easy to Use – Simply mix with water and apply.


How to Use PREP ETCH

  1. Prepare the Surface – Sweep away loose dirt and debris. If there’s oil, use a degreaser first.

  2. Mix the Solution – Dissolve 1kg of PREP ETCH in 5 litres of water.

  3. Apply Evenly – Pour the solution onto the surface using a plastic watering can. Make sure the surface stays wet.

  4. Wait & Scrub – Allow 5-15 minutes for bubbling to occur, then scrub with a stiff broom.

  5. Rinse Thoroughly – Wash off with clean water while scrubbing to remove residue.

  6. Check the Surface – The concrete should have a texture similar to medium-grit sandpaper. If needed, repeat the process.


Important Tips

  • Do not use on previously coated concrete.

  • Allow new concrete to cure for 28 days before etching.

  • Always rinse thoroughly to prevent adhesion issues.


By choosing MASTERMAX PREP ETCH, you’re not only ensuring a strong, long-lasting bond for your coatings but also making an environmentally responsible choice that keeps your outdoor spaces safe for your family, pets, and plants.
