The gallonage required for Wood Finishes is always an “approximation.” The air temperature during application, dryness and porosity of the wood, the wood species, and how you apply it will affect coverage. The following is what we recommend on average if applied strictly according to directions.

Square footage = length X height or length X width Note: add in extra sq footage for deck rails

New or Fairly New Decks – Deck & Fence Formula (225–250 sq ft per gallon per coat approx)

200 Sq ft = 1 ¾ gals will provide 2 coats
300 Sq ft = 2 ½ gals will provide 2 coats
500 Sq ft = 4 ½ gals will provide 2 coats
Note: Exotic wood species such as Tiger Wood, Teak, etc. figure 10% less gallonage

Older Weathered Decks – Deck & Fence Formula (200–225 sq ft per gallon per coat approx)

200 Sq ft = 2 gals will provide 2 coats
300 Sq ft = 3 gals will provide 2 coats
500 Sq ft = 5 gals will provide 2 coats

Rough Sawn Fencing New – Deck & Fence Formula (200 sq ft per gallon per coat approx)

Don’t forget to double square footage if you plan to treat both sides of fence
500 Sq ft = 5 gals will provide 2 coats
1000 Sq ft = 10 gals will provide 2 coats
1500 Sq ft = 15 gals will provide 2 coats

Rough Sawn Siding New or Older Log Homes – Log & Siding Formula (225–250 sq ft per gallon per coat approx)

Note: Add 15 to 20 % to sq footage to allow for log curvature
Don’t forget to add in square of exterior wood soffits, fascia boards, exterior posts, and beams, etc.
500 Sq ft = 4 ½ gals will provide 2 coats
1000 Sq ft = 9 ½ gals will provide 2 coats
1500 Sq ft = 13 ½ gals will provide 2 coats
For final 3rd coat of Clear UV use 1 gal to every 250–275 sq ft

New Log Homes or Smooth Wood Exterior Siding – Log & Siding Formula (250–275 sq ft per gallon per coat)

(On smooth siding, formula used dependent on wood species and smoothness)
Note: Add 15 to 20 % to square footage to allow for log curvature
Don’t forget to add in square of exterior wood soffits, fascia boards, exterior posts, and beams, etc.
500 Sq ft = 4 gals will provide 2 coats
1000 Sq ft = 8 gals will provide 2 coats
1500 Sq ft = 12 gals will provide 2 coats
For final 3rd coat of Clear UV add 1 gal to every 275–300 sq ft

Interior Wood Beams, Wood Ceilings, Wood Trim, Wood Doors, Wood Windows, etc.

Log & Siding or Deck & Fence Formula = Smooth wood will absorb 1 gal per every 225–275 sq ft approx
(On smooth siding, formula used dependent on wood species and smoothness)
Crystal Urethane = 400 sq ft per gallon per coat (see application guide for appropriate number of coats)
Log Yard Treatment = One gallon will treat 200–275 sq ft depending on wood age and porosity


Masonry & Concrete Sealers, Wood Stabilizer

Internal Concrete Sealer = 1 gallon will treat 150–250 sq ft depending on age/porosity of concrete
May require 1–2 additional coats

Masonry Top Sealer = 1 gallon will treat 250–300 sq ft on very smooth dense concrete
1 gallon will treat 100–225 sq ft on bricks, pavers, or other more porous masonry

Internal Wood Stabilizer = 1 gallon will treat 150–250 sq ft depending on age/porosity/species of wood
