Notes & FAQ
How should I estimate board gaps?
Most decks use 3–8 mm gaps, which equals about 5–10%. Leave gap at 0% for concrete or tile terraces.
When should I use primer?
Turn on primer for bare wood or porous concrete. For recoats with self-priming paints, disable primer or set coats to 0 if the product label allows.
How do I include railing or steps?
If you know the railing height and run, multiply them and enter the area here. For detailed pickets/rails, estimate in the Fence Paint calculator and paste the paintable area.
