Plastering a pool is a crucial step in construction or renovation, ensuring a smooth and durable finish. To simplify this process, we’ve created the Pool Plaster Calculator, a handy tool that helps you estimate the surface area and plaster volume required for both rectangular and round pools.

Below, we explain the formulas used in the calculator, along with their LaTeX representations and practical examples.

1. Rectangular Pool Calculations

Surface Area of a Rectangular Pool

For a rectangular pool with:

Length (L)
Width (W)
Depth (D)

The total surface area (including the bottom and all four sides) is calculated as:

$\text{Surface Area} = (L \times W) + 2 \times (L \times D) + 2 \times (W \times D)$

Plaster Volume for a Rectangular Pool

Once the surface area is known, the plaster volume (V) is calculated by multiplying the surface area (SA) by the plaster thickness (T):

$V = \text{Surface Area} \times T$

2. Round (Circular) Pool Calculations

Surface Area of a Round Pool

For a round pool with:

Diameter (D) (or Radius (R) = D/2)
Depth (H)

The total surface area (including the bottom and side walls) is calculated as:

$\text{Surface Area} = \pi R^2 + 2 \pi R H$

Plaster Volume for a Round Pool

The plaster volume (V) is then:

$V = \text{Surface Area} \times T$

Example Calculations

Example 1: Rectangular Pool

Length (L) = 10 m
Width (W) = 5 m
Depth (D) = 2 m
Plaster Thickness (T) = 0.02 m (20 mm)

Surface Area:

$= (10 \times 5) + 2 \times (10 \times 2) + 2 \times (5 \times 2)$

$= 50 + 40 + 20 = 110 \, \text{m}^2$

Plaster Volume:

$= 110 \times 0.02 = 2.2 \, \text{m}^3$

Example 2: Round Pool

Diameter (D) = 8 m → Radius (R) = 4 m
Depth (H) = 1.5 m
Plaster Thickness (T) = 0.015 m (15 mm)

Surface Area:

$= \pi \times 4^2 + 2 \pi \times 4 \times 1.5$

$= 50.265 + 37.699 \approx 87.964 \, \text{m}^2$

Plaster Volume:

$= 87.964 \times 0.015 \approx 1.32 \, \text{m}^3$

Conclusion

With the Pool Plaster Calculator, you can quickly determine the required plaster quantity, saving time and reducing material waste. Whether you have a rectangular or round pool, simply input the dimensions and plaster thickness to get accurate estimates.
