Running out halfway through a job means downtime and a second delivery. Over-ordering ties up cash and shelf space. A quick estimate before you ask for a quote gets you the right amount the first time.
1. Measure the area
Multiply length by width for each surface, in square feet, and add them up. Remember the parts that are easy to miss: walls and curbs on a parking deck, both sides of a railing, the shell and the roof of a tank. A rough sketch with measurements is all we need.
2. Check the coverage
Coverage depends on how porous and rough the surface is. Smooth steel takes far less than rough, thirsty concrete. As a guide, one 20 L (5.3-gallon) pail covers about:
- Metal Coating: 3,150 to 4,200 sq ft per coat.
- Concrete Coating: 1,050 to 3,150 sq ft.
- Algae Guard: 2,100 to 4,200 sq ft.
- Natural Seal: 1,050 to 2,100 sq ft.
For porous or rough surfaces, plan at the low end of the range. Add about 10% for overspray and touch-ups. Each product page lists its coverage and drying times, and you can download the data sheet there too.
A worked example
A 6,000 sq ft parking deck in older, porous concrete, protected with Concrete Coating. At the low end of 1,050 sq ft per pail, that is just under 6 pails, plus 10% spare: about 7 pails, or 140 L. If you are protecting the stairwell walls with Natural Seal at the same time, those litres count toward bulk pricing too.
3. Pick the pack size
- 20 L (5.3-gallon) pails. Held in US stock. The minimum order is one pail.
- 1,000 L IBC totes. Factory-direct, for large projects and regular users.
- Bulk pricing from 500 L. You can mix products across the range to reach it.
We do not offer free samples. If you want to try a product on your own surface first, a single pail is the way to do it.
4. Plan the delivery
- Pails ship by ground from California: 2 to 5 business days across the contiguous US.
- For Canada and Mexico, timing depends on the carrier and destination, and we confirm it when your order ships.
- Totes come from Vietnam and typically take 4 to 6 weeks from the port to you.
- We do not currently ship to Alaska or Hawaii.
For a project with a fixed start date, order totes well ahead, or start on pails and switch to totes for later phases.
Let us do the math
Send us the products, the area and the surface type, with a photo if you can. We will quote the best mix of pails and totes, and the price.
