Make sure that a sufficient amount of paint is purchased and prepared for the painting job. This is essential when semi-gloss needs to be mixed with other types of paint to obtain a specific sheen or luster. Trying to duplicate the luster can be unmanageable when the amount of paint is not appropriated correctly. To estimate the amount you need, measure the space you want to paint and calculate it in square feet. Generally, a gallon of paint covers 300 to 400 square feet. This estimate, however, applies to primed and well-prepared surfaces without any embellishments or grooves. Surface conditions and designs also play a part in the amount of paint that a surface may need. In addition, remember to double the amount you need if you will be using two coats of paint. To get a more accurate estimation of the amount of paint you will require, it often is best to ask an employee at your local paint store.
Make sure the paint is thoroughly mixed. Start by pouring off floating thin paint on top into a separate receptacle. Any paste that settles at the bottom of the paint should be stirred and blended into the rest of the paint with a paddle. Then slowly and carefully mix in the thin paint that was taken out initially, with the paddle going in figure eights. Pour the paint from one container to another a few times to achieve even blending and uniform thickness.
Achieving desired colors often entails mixing semi-gloss paints with other types. This is doable as long as the base remains consistent – water-based paints should be mixed with water-based paints, and oil-based paints should be blended with oil-based paints. Also, when mixing with an old paint, screen out any impurities by allowing a small piece of window screen to float down and carry lumps or dirt down into the paint can’s bottom as the paint in the can is gradually reduced. When mixing two different colors, mix a small amount first to see if the end result will be the color you want. Get a larger container and pour in the first paint. Gradually add the next color, using the same mixing technique as above.
Generally, paint manufacturers produce oil-based interior semi-gloss paints that possess more luster than interior latex semi-gloss paints. Trim and woodwork are ideal surfaces to use semi-gloss paints on. Semi-gloss oil or latex paint can be applied on living room woodwork, while woodwork in kitchens needs semi-gloss oil paint. Use semi-gloss latex paint on kitchen walls. For bathrooms, use special semigloss paints that are resistant to mold, moisture and mildew. Make sure your surface is dry, dull and clean before applying. A primer needs to be applied on a wall that is being painted for the first time, while a pre-painted wall needs to be thoroughly washed with water and commercial detergent before being rinsed off completely with water. Then dry before painting.
