Schmith polystyrene rasps - ideal for polystyrene foam.
Styrofoamrasps are indispensable tools for those involved in building insulation, renovation and other work on polystyrene foam. The rasps are used for precise shaping, leveling, sanding and overall processing of polystyrene foam panels. Friction of polystyrene foam is a key process that ensures proper preparation of the substrate for mesh and plaster, which directly affects the durability of the work done.
Styrofoamscrapers, also known as trowels, are hand tools designed for efficient processing of polystyrene foam panels. They are mainly used to remove excess material, level out irregularities and accurately shape the boards. Working with rasps, you can get a smooth and uniform surface, which is necessary for the application of layers of glue, mesh or plaster.
Construction of the rasp for polystyrene foam
All rasps for polystyrene foam consist of the same elements, which are:
- Working plate - made of durable, deformation-resistant metal, such as stainless steel or aluminum. The rasp plate is perforated, equipped with holes that surround sharp teeth, which are used for effective abrasion of polystyrene foam. The rasp's teeth are designed to remove excess material without crushing it, while the holes inside them are used to drain away spoils that could clog the working surface and prevent effective machining.
- Handleof the rasp - mostrasps are equipped with an ergonomic handle, attached to the work plate on one or both sides. Handles are usually made of plastic, rubber-coated plastic or wood. To maintain high comfort during work, they are often covered with an additional non-slip layer.
- Additional reinforcements - professional styrofoam rippers have reinforcements in the form of ribbing or profiling, located on top of the work plate. Reinforcement allows intensive and long-term use of the tool, without the risk of premature destruction.
Where, when and for what purpose are rasps used?
Rappers are used wherever there is polystyrene foam and there is a need to process it. The most common are works related to:
- Insulating facades - they are used to remove irregularities from Styrofoam panels, formed after they are glued to the walls. Rappers make it possible to perfectly level the surface of glued plates, creating a smooth plane for gluing subsequent reinforcing layers and final plastering. Rappers are also used to level out faults arising at the joints of the panels.
- Substrate preparation - rasps are often used to matt polystyrene surfaces before applying adhesive to them, in order to improve adhesion.
Types of styrofoam peelers
Styrofoam rasps differ from each other in shape, design and the type of working plate used. There are several basic types, such as:
- Straight rasp - also known as a flat rasp or universal rasp, is characterized by a flat, rectangular working plate and one or two handles. They are used for leveling large, flat areas of polystyrene, so they come in a wide range of sizes, from 250 to 600 mm in work area length.
- Angle rasps - or corner rasps, are designed for working external and internal corners. They have a working plate that is bent at a right angle, which allows two corner planes to be worked on simultaneously, enabling a perfect line to be achieved.
- Grooving rasp - also called rustication rasp, is used to create grooves on the surface of polystyrene facades. They have a working plate, specially profiled or equipped with blades, used for precise cutting of a repetitive pattern.
- Rapperswith interchangeable plates - professional rasps often have an interchangeable work plate system, allowing the use of a single ripper for different tasks.
What to pay attention to when choosing a rasp for polystyrene boards?
When choosing a rasp for polystyrene foam, it is worth paying attention to its parameters and features, defining the efficiency and quality of the work done. The characteristics of rasps that should be paid attention to are:7
- Material of the working plate - a high-quality polystyrene rasp should have a working plate made of stainless steel or aluminum and additionally reinforced with ribs.
- The shape of the teeth - the teeth of the rasp can be sharp, pointed, straight, milled or profiled. The shape of the teeth affects the aggressiveness of the rasp and the finish of the machined surface.
- Density of teeth - the density of the tooth arrangement affects the smoothness of the surface. The denser and finer they are, the smoother the surface.
- Through holes - the holes on the workplate are responsible for draining the abraded material, preventing clogging of the work surface.
- Type of handle - a single handle ensures even pressure on the work surface, while two handles allow precise guidance of the rasp and even distribution of force.
