The first thing we like to let folks know is that you can always come back to Bonds Décor to buy more stains. That’s why it really is preferable to buy too little stain than too much. Calculate the surface area being stained and divide that by the number of square feet a gallon of stain can cover. We can help you find this number, or the stain company’s website should have this info. Also important for stains is the type of surface you’ll be staining. A rough or porous surface will require more stain than a smooth, well-sealed surface. Your Bonds Décor Ottawa stain specialist will be happy to work with you to get the right amount of stain for your home staining project.
