How Much Paint Should I Buy

Generally, one gallon of paint will cover approximately four hundred square feet of wall space. Keep in mind, however, that this is just a rough estimate. Some paint (usually higher quality paint) will cover more area, and some paint may take two or three coats to cover that same amount of space. When buying paint, talk to the customer-service representative. He or she will be able to tell you how well the paint will perform, and you can thus buy accordingly.

• How do you tell what four hundred square feet of wall space looks like? Well, you measure your wall multiply (yes, you do need it after school) the length of the wall by the height to get the square footage. For instance, if your wall is ten feet long and eight feet high, your square footage is eighty feet.

• There is interior paint and exterior paint. Check the label to be sure that you are buying the right paint for the job.

• What about trim paint? The trim is usually a different color from the walls of the home it can be lighter or darker, depending on your preference. For every six gallons of wall paint, you will need one gallon of trim paint. If you have a lot of trim around windows and doors, it might push your need to two gallons per every six. Trim paint is no different from regular paint—except, of course, for the color.


Interior Painting – Frequently asked questions

Can I paint directly over wallpaper?
No. Wallpaper can be painted over with the proper preparations. Be sure to remove any loose wallpaper, scuff/sand the surface, then apply interior oil-based primer.

Can I apply latex paint over oil based paint?
Yes. Be sure to prepare the surface properly before painting. Oil-based paints should be sanded to a flat finish before painting. After rinsing, apply Dutch Boy® oil-based primer and apply desired latex paint.

Can I apply paint directly over a semi-gloss paint?
No. Semi-gloss paint must be dulled to a flat finish by sanding*, allowing proper adhesion. Removing or disturbing old paint from interior or exterior surfaces by sanding, scraping, abrading or other means may produce dust, debris or fumes that contain lead. Exposure to lead dust, debris or fumes may cause brain damage or other adverse health effects, especially in children and pregnant women. Structures built before 1978 should be tested by a licensed inspector prior to removing or disturbing old paint.

Can I use exterior paint on the inside of my house?
No. Exterior paints are formulated to be more flexible to withstand temperature and climate change.

How can I best prepare my walls before I paint?
Walls that have never been painted should have a recommended primer applied before painting. For previously painted walls, thoroughly wash them with a mild soap and water solution, then rinse with clean water. If your existing surface was painted previously with semi-gloss paint, the surface should be lightly sanded to a duller finish. If the walls have not been painted in five years or longer or are stained then primer should be used.

How much paint do I need?
To achieve one-coat coverage, paint should be applied at a maximum of 400 square feet per gallon. Rough or textured surfaces may require more paint. On these areas allow for 125-300 square feet per gallon.

How do I prepare the surface?
As a general rule, all surfaces should be clean before painting. Remove any loose, peeling paint, and/or any other substrate that is on the surface*. Scrub all surfaces to remove all dirt, grease, oil, etc. Rinse surface well and allow to dry. Apply appropriate patching material to cracks, nail holes, or other surface imperfections, sand smooth, and remove sanding dust.

*If your existing surface is glossy, dull surface by sanding or use an abrasive cleaner. Remove any residue.

How do I take care of my freshly painted surface?
Freshly painted surfaces may be washed after 30 days. Avoid touching, wiping, or wetting any freshly painted surface for 30 days. After that time dirt and stains may be removed with a mild, non-abrasive cleaner and water. Do not place objects on windowsills and shelves until paint is thoroughly dry.

How long should I wait before applying a second coat of paint?
A second coat of latex paint may be applied 6 hours after the first coat. With oil-based paint, you should wait 24 hours between coats.

Should I paint the trim before or after I roll the walls?
The wall area around the doors and windows and along the ceiling should be cut in with a brush, this will prevent the wall from having an obvious and unsightly picture frame effect. Then, the main part of the wall can be painted with a roller, rolling into these areas.

Why do I need to use a primer?
Primers are specifically formulated to seal porous surfaces, block stains, as well as to insure the proper adhesion of the topcoat and produce the best possible coverage.

What is the proper order to follow when painting a room?
When painting a room, the ceiling should be painted first, followed by the walls, then the trim (including doors and windows) and finally the baseboards.

When should I apply?
Room and surface temperature should be between 50 and 85 degrees. Paint dries best between 65F and 85F. Allow at least 4 hours of drying time before recoating.

What is the proper rolling technique?
Fully load the roller with paint by dipping the entire cover deep into the tray of paint. Carry as much paint to the surface as possible. Make a letter “V” in a small 2 foot by 2 foot area with a generous roller load of paint. Fill in the “V”, spreading the paint evenly from left to right. Lightly smooth out with downward motions. Repeat “V” with a freshly loaded roller for every 2 x 2 foot area.

Using paint is an easy, very economical, and effective way to decorate a room. There are many different types and colors of paint now available and a range of easy-to-do paint effects.

Paint can also disguise flaws in walls and ceilings.

PAINT IS QUICK & EASY TO USE


HOW MUCH PAINT?

To estimate the amount that you will need, read the instructions, taking into account the number of coats required and the type of surface-a porous surface, for example, will need more paint than a surface that is nonporous. Useful guidelines are:

• Divide the room into units of the same color or type of paint.

• Multiply together the height and width of each unit.

• Add together the unit totals.


COLOR Frequently asked questions

How do colors effect room size?
Generally, warm colors like reds, oranges, and yellows close in a space. Blues, greens, and violets tend to make a room look larger. Dark colors have a diminishing effect. Whites are always a good choice for making a room look larger.

My room has a chair rail and I am using two colors….?
This depends on the look you want to achieve. If you want an open, airy look, always paint the portion of the wall below the chair rail darker allowing the lighter color to dominate.

Should trim work be painted the same color as the walls…?
Use the same color to hide trim work, use a lighter or darker color to bring out the trim work and add highlights.

Will the paint I choose look lighter or darker on the wall?
Larger surfaces make the paint appear darker. As a general rule, always choose colors that are a shade or two lighter than what you want. Do keep in mind that colors can also appear lighter or darker depending on surrounding colors and lighting.

What is the best way to decide which color is best for my room?
Take color chips home to determine the color of your room. A nice technique is to hold the color chips in the daylight and at night so you will see how lighting will effect your color choices.

What color should I paint my ceiling?
White or off-white colors will create the illusion of having a higher ceiling and more open space. Whereas medium to dark colors will create the illusion of lowering the ceiling. Customarily, white or off-white tend to be used.

Will the paint actually match the color chip?
As a general rule, paint on a color chip will appear slightly lighter than when applied in a room. Always take into account the sheen of the paint, the lighting in the room, and other colors that are in the room.
