Polish smarter with accurate dosing every project. Adjust coats, dilution, and wastage for real conditions. Plan refills, save money, and protect wood longer always.
| Scenario | Area | Coats | Rate | Dilution | Wastage | Estimated finish |
|---|---|---|---|---|---|---|
| Indoor table, cloth | 3.50 m² | 2 | 18 ml/m²/coat | 1:2 | 6% | ≈ 134 ml |
| Garden bench, porous | 22.00 ft² | 2 | 0.60 ml/ft²/coat | No | 10% | ≈ 64 ml |
| Fence section, spray | 14.00 m² | 1 | 24 ml/m²/coat | 1:3 | 12% | ≈ 438 ml |
Base finish (ml) = Area(m²) × Coats × Rate(ml/m²/coat)
Adjusted finish (ml) = Base × MethodFactor × AbsorptionFactor × FinishFactor
Total finish (ml) = Adjusted × (1 + Wastage%/100)
Concentrate (ml) = Total × (PolishParts / (PolishParts + DiluentParts))
Coverage rate is the biggest driver of dose accuracy. Many liquid polishes fall within 15–30 ml per m² per coat when applied by cloth, while waxes can exceed that range due to thicker films. Use the product label first, then confirm with a 1 m² test patch and measure the volume used. Enter the tested value as the coverage rate to match your technique. Record temperature and humidity, because they alter spread noticeably.
Dilution changes spread and leveling, but it must be label-approved. The calculator splits total finish into concentrate and diluent using parts. For example, a 1:3 mix means 25% concentrate and 75% diluent by volume. Mix in a marked container, stir gently, and keep notes so every batch matches. If the surface flashes dry too fast, reduce dilution or increase coat count rather than flooding the wood.
Application method affects loss and film thickness. Cloth usually yields the lowest waste, pads add moderate uptake, and spray adds overspray and airborne loss. Absorption also matters: tight-grain hardwoods often need less finish, while weathered or porous outdoor wood can require 20–30% more. Select the closest absorption level to avoid underbuying and uneven sheen. When switching methods mid-project, rerun the calculator to keep totals consistent.
Container planning converts the final dose into a count of refill units based on your chosen container size. This helps you compare 250 ml, 500 ml, and 1 L options quickly and reduce last-minute store runs. If you are coating large areas, choose a larger container size to reduce changeovers and measurement errors, then round to the nearest 10 or 25 ml for speed.
Wastage captures drips, cloth retention, and leftover mix. For careful indoor work, 5–8% is common; for outdoor or spray application, 10–15% is safer. Keep containers closed, work with ventilation, and avoid ignition sources because some polishes and thinners are flammable. Clean tools promptly to reduce waste and maintain consistent coverage across coats. Budget extra for edges, joints, and end grain absorption.
Select ft² for area and ml/ft²/coat for rate. The calculator converts internally and still outputs milliliters, liters, and ounces for easy measuring.
No. Enable dilution only when the manufacturer allows it. If dilution is not recommended, choose “No dilution” to keep the dose as a single finished volume.
Use 5–8% for careful cloth work indoors, 8–12% for mixed conditions, and up to 15% for spray or rough outdoor surfaces where loss is higher.
Porous or weathered wood absorbs more finish and can require thicker application to achieve even sheen. The absorption factor increases the base dose to reduce shortages.
It can help planning if you enter the correct coverage rate and coat count. However, drying behavior and film build vary, so test a small patch and adjust inputs.
Rounding simplifies measuring in real conditions. Choose 1 ml for precision, 10 ml for routine work, or 25 ml when estimating large batches quickly.
