| Item | Area | Coats | Wax type | Estimated needed |
|---|---|---|---|---|
| Patio table (top + edges) | 18 ft² | 2 | Paste wax | ~18–22 oz |
| Two chairs (slats) | 22 ft² | 2 | Beeswax blend | ~20–26 oz |
| Garden bench (open grain) | 28 ft² | 3 | Carnauba blend | ~34–45 oz |
The calculator estimates wax needed using this structure:
Coverage is per coat; factors help match real garden furniture surfaces.
Outdoor tables, benches, and planters rarely share the same shape. Break each piece into rectangles and cylinders, then total the visible faces. For quick estimating, add 8–12% for legs, rails, and underside edges that still catch moisture.
Coverage is expressed as square feet per ounce, per coat. Paste wax often spreads thicker, so practical rates can be 2.0–2.5 ft²/oz. Liquid blends can reach 2.8–3.5 ft²/oz on sealed surfaces. Beeswax mixes often sit near 2.4–2.8 ft²/oz because they buff with a heavier film. Use a custom rate when a label lists grams per square meter; 1 oz is about 28.35 g and 1 m² is about 10.76 ft².
Two coats suit seasonal touch‑ups on protected patios. Three coats is common for high‑traffic seating and tabletops. Four coats can help on exposed, sun‑heated surfaces where water beading matters after curing. If you recoat yearly, reduce porosity and waste assumptions after the first season because the surface becomes more sealed.
Open‑grain woods and weathered lumber absorb more wax, so a porosity factor of 1.20–1.50 is realistic. Slats, carvings, and woven details increase applicator passes; a 1.05–1.20 detail factor covers that extra spread. Below 20°C, wax stiffens and transfers less evenly; plan 3–6% more wax for every 10°C drop, up to a practical ceiling near 20%.
Match the container size to your workflow. Smaller tins reduce leftovers for single items, while larger jars minimize per‑ounce cost for multiple pieces. Rounding up is safer when you expect rework, sanding, or uneven absorption. Many DIY projects finish a 16 oz tin on roughly 30–45 ft² per coat, depending on texture. Download the CSV to compare scenarios and keep a simple maintenance log.
Approximate curves as rectangles using the longest length and widest width, then reduce by 10–15% for rounding. For multiple identical chairs, measure one carefully and multiply to avoid repeated errors.
Raw teak is moderately porous. Start around 1.15–1.30, then adjust after a small test coat. If the first coat soaks in fast and looks dry, increase the factor slightly.
Cooler temperatures thicken wax and reduce spread, so you need more product to cover the same area. Warmer conditions improve flow, but very hot sun can cause uneven buffing, so work in shade.
Round up when you cannot easily buy partial containers, when surfaces are uneven, or when you expect touch‑ups. Nearest whole works for controlled, indoor pieces with consistent wood and stable conditions.
Yes. Select a wax type closest to your blend, or choose the custom rate and enter the label’s coverage figure. Keep coats and factors consistent so brand comparisons stay meaningful.
Use a measured applicator pad, apply thin coats, and buff promptly to avoid heavy buildup. Pre‑clean surfaces so wax doesn’t load onto dirt. Store the lid tightly to prevent drying between sessions.
