Plastering runs in stages and each has a tool that does nothing else. The mix is carried on a hawk, laid on with a trowel, ruled flat with a darby, floated to consolidate it and then finished. A trowel will not do a float's job and the reverse is equally true. Skipping the float stage is what leaves a surface that looks flat and is not consolidated.
Trowel size decides how much is laid per pass and how well the blade follows the wall. A 280mm stainless trowel is the general size for laying and finishing. Venetian trowels at 200mm and 240mm are smaller and shaped for polished finishes rather than base coats. Blade flexibility also changes with size, and a longer trowel follows a wall more closely than a short one.
Float material changes what the surface is left like. A polyurethane float at 280 x 140mm or 320 x 180mm opens the surface and consolidates it without dragging, which a steel trowel at that stage would do. Both float sizes are polyurethane, which does not stain the surface the way a wooden float can.
Keying between coats matters where a second coat has to hold. A scarifier at 135mm scratches the surface so the next coat keys into it rather than sitting on a smooth face. A hawk at 330 x 330mm carries the mix. Send the finish wanted to 07754288583 on WhatsApp. Expert soft grip London pattern trowels sit alongside for brickwork rather than plastering. Venetian trowels are held in four sizes so the finish and the reach can both be matched.
