Estimating Surface Area

How to Estimate the Amount of Coating Materials Required to Properly Cover 3 Dimensional Objects

When ordering spray on or other coating materials for proper coverage, you must first determine the square footage of any surface you need to protect. This applies to coatings from Spray Lining and Coatings, or any other manufacturer. We have developed some useful tools initially designed for our dealers, but these can be equally beneficial to DIY customers as well. Originally published on our dealer website, you can take advantage of them by following these links:

Remember that once you determine the square footage, you will have to consider the thickness of your coating requirements. Depending on your application, this can range from 15 mils to 125 mils on average. Never accept a generic answer regarding coverage from any coating manufacturer. Always ensure that the coverage is equal to the protection level you are expecting.

When using the surface calculator to estimate surface of objects where all sides are to be coated (drums, boxes, etc.), be sure to double the measurement for lower surface. Our pond and pool surface calculator does not add that surface area since it will not be coated in those applications.

    Your calculators for true qty of polyurea needed are the most honest tools I found. I’ve used your SLC bedliners but as a landscaper I got into high end water featues, koi pond builds and now doing a cascade repair. SLC Pond Coating is different than your bedliner… a little more costly, but works better on ponds.
