Korjaustäytteitä

Korjaustäytteitä, known in English as repair fillers or patching compounds, are substances used to fill cracks, holes, or other imperfections in surfaces. They are commonly employed in construction, DIY projects, and automotive repair. The primary purpose of a korjaustäyte is to restore a surface to a smooth and even condition, preparing it for further treatment such as painting, sanding, or varnishing.

These fillers come in various forms, depending on the material they are intended to repair and the desired application. Common types include those based on gypsum, cement, epoxy resins, or acrylic polymers. Gypsum-based fillers are often used for interior walls and ceilings to repair minor damage. Cement-based fillers are suitable for exterior surfaces, masonry, and concrete repairs due to their durability and water resistance. Epoxy and acrylic fillers are known for their strength and versatility, often used for more demanding repairs, including those involving metal or wood.

The application process typically involves cleaning the damaged area, mixing the filler if it's a two-part product, and then applying it using a trowel, putty knife, or spatula. Once applied, the filler is allowed to cure or dry, after which it can be sanded smooth and finished to match the surrounding surface. The choice of korjaustäyte depends on the specific material being repaired, the size and depth of the damage, and the environmental conditions the repair will be exposed to.
