Report from the Channel ENTÃO MARCIA details how much it costs to plaster a 102 m² house when the bill includes 840 m² of walls, smooth plaster, plumbing, conduits, sand, cement, dumpster, scaffolding, and extra charges that many homeowners forget in the initial budget

In a 102 m² house, the bill for plastering reached about R$ 40,400, considering 840 m² of walls, smooth plaster, plumbing, conduits, counter frames, materials, dumpster, and scaffolding.

The case, reported by the Channel ENTÃO MARCIA, helps those planning construction to understand that the cost of plastering does not depend solely on the price per square meter. Preparatory services, window finishing, and support expenses can significantly alter the final budget.

How much it costs to plaster when the calculation includes the entire area

Although the house has 102 m² of construction, the area effectively considered for plastering was much larger. Among walls, external and internal walls, the total reported reached 840 m² of surface.

Items charged separately changed the budget

The stage also involved services prior to wall finishing. It was necessary to open walls, embed outlet boxes, run conduits, and execute the internal plumbing of the house.

For cuts, boxes, and conduits, the charge was R$ 600. The internal plumbing cost R$ 2,200. The counter frames were R$ 600, after a discount related to a change in the kitchen ceiling.

The construction also included a charge of R$ 100 per stone for window sills and drip edges. The house had six windows and two sills accounted for, an example of an expense that often appears when the initial budget does not detail everything.

Materials totaled almost R$ 8,000

The list of materials reported included 22 m³ of fine sand, at R$ 140 per meter, totaling R$ 3,080. Also used were 110 bags of cement, averaging R$ 32 each, totaling R$ 3,520.

The hydraulic material for internal installation and external points was R$ 102. The conduits cost R$ 260, as part of the material was leftover from a previous stage of the construction.

With these items, the total material cost reached R$ 7,882. The account does not rule out small occasional purchases, such as nails or additives, but the value presented remained within this range.

Planning needs to anticipate unforeseen events

In addition to execution and materials, the construction had R$ 700 for a dumpster, referring to two months, and R$ 200 for renting 17 linear meters of scaffolding.

The sum shows that the initial estimate of less than R$ 30,000 was far from the actual expense. For those researching how much it costs to plaster, the main lesson is to request a detailed budget, separate labor, material, and extra services, and reserve a margin for unforeseen events before signing a contract with a professional.
