By placing a bit on one corner of the lath to produce sure it retains test it. Spread it using a mason’s trowel over the lath, spreading it with the flat-bottom and scooping up plaster together with the conclusion of the trowel, about 3/8-inch-thick. Scrape or “scratch” it with the notched side of the trowel as it starts to set.
Let the scratch coat treatment completely, usually at least 4-8 hrs, maintaining it somewhat moist using a sprayer while it cures. Mix a batch of “brown coat” plaster, with a few fine sand inside, and distribute it on the very top of the scratch coat, about 1/4 inch thick. Smooth it. Let that coat treatment a T least 2 4 hrs, misting it to keep it somewhat moist.
Add a complete coat, utilizing a plaster for finishing, with all the trowel designated. Spread this 1/8 to 1/4 inch thick and sleek it with the straightedge of the trowel.
