Primary Pro 100mm Grinder Head

The Primary Pro Grinder Head grinds a flat surface into the wall, creating a small 4mm indentation around the pipe entry point. This small indentation allows sealing materials to sit flush against the wall, making it much easier to achieve a secure and weatherproof seal.

The grinder head is commonly used when installing Primary Pro Sealing Rings, allowing the ring to sit neatly within the indentation for a clean, professional finish. It can also be used when sealing directly with Primary Pro Bond & Seal.

By preparing the wall surface correctly, the Primary Pro Grinder Head helps create a faster, neater and more energy-efficient installation while improving the overall appearance of the pipe entry point.
