How to use

Ensure the surface is prepared, clean and free of loose debris before applying plaster or filler. Attach a sharp replaceable blade to the putty knife according to the manufacturer’s fitting method. Apply plaster or filler with a hawk or trowel and use the 80 cm putty knife to spread and level the material across the surface in smooth, overlapping strokes. Keep a consistent working angle and moderate pressure to avoid gouging while achieving an even finish. Replace the blade when signs of wear or nicks begin to affect the finish quality.

For best results use the GEKO 80 cm finishing putty knife with compatible replaceable blades and maintain blades clean between uses. Store knives flat and dry to avoid blade damage or corrosion; replace blades promptly when worn to preserve finish quality and reduce rework.
