حاسبة دهان مسابح مجانية — تقدير اللترات ومساحة الطلاء

Measure the wetted floor and wall area of the drained shell, adjust for porosity, multiply by the number of coats, and divide by the practical spread in square metres per litre printed on the coating datasheet. This calculator automates a standard rectangular model with shallow and deep ends for you.

We estimate total wetted area as floor area (length × width) plus wall area modelled as (length + width) × (shallow depth + deep depth) for a simple hopper-style pool, then apply a surface factor, assume two topcoats, and divide by your spread rate. Primer volume uses a single full application over the same adjusted area when the substrate needs sealing.

Not always. Solids content, film thickness, and whether you are converting systems all change consumption. Use the spread values from the actual product you intend to apply; rubber and epoxy lines on the same pool can differ.

Bare cementitious surfaces, pebblecrete, and marble-sheen finishes are usually sealed before high-performance topcoats. Repainted epoxy over sound epoxy may not need the same primer stage—always follow the manufacturer’s system sheet.

This tool is optimised for rectangular outlines. Curved walls, steps, benches, and spas add area the model does not automatically include, so add manual allowances or ask a pool contractor to field-measure.

Kit counts round litres up to 4-litre increments for quick shopping guidance. Real kits vary (for example 3.5 L, 4 L, or 5 L), so treat the count as approximate.

Yes. Bright-to-dark or white-to-blue transitions often need additional coats; increase coats in your planning or lower the spread figure to reflect extra build.

No. HomeSols provides a neutral geometry-based planner. Brand-specific pack sizes, tie-coats, and warranties differ, so always finalize quantities with the supplier whose system you are applying.
