Waterlox® produces a variety of different products that may have different spread rates. They can generally be classified as *Buffer Applied ^{1} coatings* and

*Wet Applied coatings (brush/pad)*.

Our Find Your Finishing System tool will recommend 3 total coats for almost all projects. Typically, they will consist of one coat of a *Buffer Applied*^{1} coating and 2 coats of a *Wet Applied* coating, although there are some combinations that may vary.

The important take away is that the *Buffer Applied*^{1} coatings have a much higher spread rate of 3200-4000 sq. ft. per gallon per coat and the *Wet Applied* coatings are 500 sq. ft. per gallon per coat.

Calculate the amount of product needed for each coat using the following formula:

(Total Square Footage of Project)÷(Spread Rate of Product)

It is a good idea to err on the higher side for projects to ensure you do not run out in the middle of the application. Most products can be stored for long periods of time if done properly. See our Storage of Waterlox® Products guide for more information.

## Buffer Applied^{1} Coatings

1 Gallon (128 oz.)=3200-3800 sq.ft.

1 Quart (32 oz.)=600-800 sq.ft.

1 Pint (16 oz.)=300-400 sq.ft.

1 Half Pint (8 oz.)=150-200 sq.ft.

2 oz. Bottle=20-30 sq.ft.

These coatings are high solids, so a little goes a long way. These coatings include our TRUETONE® and UNIVERSAL Tung Oil Sealer products. To ensure there is enough product, it is wise to use the 600 sq. ft. per QUART per coat. Note that the spread rate of a quart is a little less than expected based on a gallon (same is true of the 2 oz. bottle size; possibly more so). This is due to losses in the buffing pad itself and erring on the side of under promising to ensure enough product is purchased. Some particularly absorbent, “punky” or soft woods (e.g. pine, fir, reclaimed, rough-sawn, dry, etc.) may even need a little more product.

**Examples**

BASED ON A 1500 SQ.FT.PROJECT:

(1,500 sq.ft.)÷(600 sq.ft.)/QUART)=2.5 Quarts

BASED ON A 250 SQ.FT.PROJECT:

(250 sq.ft.)÷(300 sq.ft.)/PINT)=0.833 Pints

BASED ON A 50 SQ.FT.PROJECT:

(50 sq.ft.)÷(150 sq.ft.)/(half pint)=1/3 of a half pint

Very small projects (end tables, some furniture, small woodworking projects, etc.) can usually be done with 1, 2 or 3 of our 2 oz. bottles. Note that the spread rate of a 2 oz bottle is less than expected based on a gallon (more so than a quart). This is due to losses in the buffing pad itself and erring on the side of under promising to ensure enough product is purchased. Some particularly absorbent, “punky” or soft woods (e.g. pine, fir, reclaimed, rough-sawn, dry, etc.) may even need a little more product.

## Wet Applied Coatings

1 Gallon (128 oz.)=500 sq.ft.

1 Quart (32 oz.)=125 sq.ft.

2 oz. Bottle=6 sq.ft.

Wet applied coatings are typically applied with a brush, pad, t-bar or other method that leaves behind a wet film layer. These coatings include our ORIGINAL, H2OLOX®, MARINE and URETHANE product lines. Because these products form uniform films there is less variability in their spread rate. At least two coats are always recommended to ensure a good continuous layer of protection that has enough thickness to be durable and waterproof. Therefore, calculate what you would need for one coat and double it to determine how much product is needed to purchase.

*****Note**: Coverage numbers are based on the recommended application method for each product. If the application method is changed, this **will** alter the spread rate. See the Number of Coats For Your Project guide for more information.

**Examples**

BASED ON A 1500 SQ.FT.PROJECT:

(1,500 sq.ft.)÷(500 (sq.ft.)/GALLON)=3 GALLONS

BASED ON A 250 SQ.FT.PROJECT:

(250 sq.ft.)÷(125 (sq.ft.)/QUART)=2 QUARTS

BASED ON A 50 SQ.FT.PROJECT:

(50 sq.ft.)÷(125 (sq.ft.)/QUART)=0.4 QUARTS

## 8 to 1 Rule

Most of our finishes will recommend a three coat process with one coat of *Buffer Applied*^{1} sealer followed by two coats of a *Wet Applied* finish. Because the spread rate of a QUART of the buffer applied^{1} coating is approximately equal to the spread rate of one GALLON of wet applied finish, the general rule of thumb is that you’ll need about 8 times the amount of *Wet Applied* finish for each amount of *Buffer Applied*^{1} coating.

**Example**

For a matte finish on 500 sq. ft. of flooring the guide recommends:

1 coat of UNIVERSAL Tung Oil Sealer

2 coats of H2OLOX® Matte Finish

(500 sq.ft.)÷(600 (sq.ft.)/QUART)=0.833 Quarts needed for the first coat

(500 sq.ft.)÷(500 (sq.ft.)/GALLON)=1 Gallon needed per coat

So total for the project, I would need about 1 quart of UNIVERSAL Tung Oil Sealer and 2 gallons of H2OLOX® Matte Finish. Two gallons = 8 quarts, so we need 8 quarts of H2OLOX® to one quart of UNIVERSAL Tung Oil Sealer.

^{1}IMPORTANT: Spread rates are based upon properly sanded wood applied with a buffing machine. Spread rates can be lower if a trowel is used for application, and significantly lower if hand-applied with a cloth or rag, or over applied. Porous or “punky” woods (e.g.: reclaimed, soft, porous, barn wood, rough-sawn, dry wood, etc.) will reduce spread rates. You may wish to order extra to avoid waiting for more to arrive if you should run out.
