How to use

Begin by preparing the surface: remove loose material, dust and grease, and ensure the substrate is suitable for putty or plaster application. Load an even amount of finishing putty onto the blade and apply with steady, overlapping passes, holding the trowel at a low angle to the surface to spread material thinly. Use long, continuous strokes across the area to level the putty, then follow with lighter finishing strokes to smooth out trowel marks. For ceilings, adjust body position to maintain consistent pressure and blade angle. Allow the compound to dry according to the material manufacturer's instructions before sanding or applying additional coats.

Usage recommendations

Clean the blade after each use to prevent dried material build-up. For best results, use the AWTools 800 mm trowel with compatible finishing putties and follow the compound manufacturer's guidelines for mixing, application thickness and drying times. Store the trowel in a dry place to avoid corrosion and maintain a flat blade for consistent performance.
