How to Budget a Painting Project

If you’re in charge of the budget for a commercial project that you’re working on, making sure you have the related costs taken into account is crucial. You don’t want to under estimate and buy too little paint, and you certainly don’t want to over estimate it and buy way too much and waste funds.

Whether you’re using normal interior or exterior paint or a protective coating such as National Coatings Surface Master, getting the right amount can make a big difference to your overall costs.

If you’re painting the outside of a building a few relatively simple sums should help you get a fairly decent idea of how many tins you’ll need. Firstly, measure the perimeter of the building and then measure the height. Multiply these two numbers to get the total of square feet of the building’s surface area. If your building has windows measure the height and width of one and multiply the numbers to get the window surface area. Do this for each window, add them together and subtract that figure from your building’s surface area.

Next divide this number (building surface minus window surface) by the coverage that is stated on the can of paint or Surface Master coating and the resulting number will be how many gallons you will need to complete your job.

Of course if you are looking to cover a flat area such as a garage or warehouse floor, the walls of a paint spray booth or even a swimming pool, your math will be much simpler to work out. All you need to do here is to multiply the height and width which will give you the resulting square footage. For example if your wall or floor is 10 foot high and 6 foot long, you have a surface area of 60 feet.

Other things to take into account when planning a budget for a commercial paint job or project is the method of application. For example, using a spray rig to apply paint or National Coatings Surface Master will use up a lot more liquid than a paint brush or roller, so you will probably need to get a couple of extra gallons to be on the safe side. Of course using a spray rig may well be your only option if you have a vast area to cover.

Also bear in mind the texture of the surface that you are painting as roughly coated surfaces use more paint than smooth ones. Generally speaking one gallon of regular, decent quality paint should cover around 350 square feet on an average smooth base.

Don’t forget that whether you’re using paint, varnish or Surface Master, you’ll also need to factor in the cost of your tools and other materials. Brushes, rollers, paint spray rigs, paint trays and protective sheeting and clothing all add up to a fair bit of expenditure too so it will be just as well to add a bit more onto your budget in case you need more paint or equipment than you anticipated.
