The Draper Plastering Scarifier is an essential manual tool for tradespeople and serious DIYers looking to effectively prepare interior and exterior surfaces for plastering or rendering. Its durable steel tines and comfortable polyurethane handle ensure excellent keying performance, providing a strong mechanical bond for new materials, though its manual nature means it requires physical effort.
Effective Keying: Specifically designed to create a strong mechanical bond for new plaster or render to adhere properly, preventing cracks and delamination. - Durable Steel Tines: Equipped with robust steel tines that resist wear and tear, ensuring long-lasting effectiveness and consistent performance across many projects. - Comfortable Polyurethane Handle: Features an ergonomic polyurethane handle that provides a secure and comfortable grip, reducing hand fatigue during extended use. - Versatile 135mm Width: The 135mm working width is an optimal size for efficient preparation of various surface areas, balancing coverage with maneuverability. - Interior & Exterior Application: Suitable for roughening both internal and external walls, making it a flexible tool for a wide range of plastering and rendering tasks.

The Draper Plastering Scarifier is engineered for one crucial task: 'keying' surfaces. Keying is the process of roughening a smooth or old surface to create a profile that new plaster or render can grip onto, forming a strong mechanical bond. Without proper keying, new finishes can crack, blister, or delaminate over time. To use the scarifier effectively, hold it firmly by the polyurethane handle and drag the steel tines across the surface you wish to prepare. Apply even, consistent pressure to ensure the tines dig in and create uniform grooves. For best results, use overlapping strokes to cover the entire area thoroughly. This tool is ideal for preparing: - Existing Plaster: Roughening old, sound plaster before applying a fresh coat. - Masonry Surfaces: Creating a suitable bond on concrete blocks, bricks, or breeze blocks before rendering. - Painted Surfaces (after treatment): Once loose paint is removed, the scarifier can help create a key on the underlying surface. Remember to work systematically and clean the tines periodically to maintain optimal performance.
