Masonry Walls and Ceilings. Interior masonry walls and ceilings above grade may, in general, be painted in much the same manner as plaster surfaces. Here again, it is necessary to allow adequate time for the masonry to dry before applying paint and, in addition, attention should be given to the preparation of the surface. When decorating a wall containing Portland cement (concrete, for example), it is essential to take precautions against the attack of alkali. For this purpose, alkali-resistant primers such as rubber-base paints may be used when oil paints are to follow.
Matt - Describes paints that give a flat, non-reflective finish. It is ideal for walls and ceilings that are not perfectly smooth.
Semi-gloss paints are very similar to gloss plaints except it has lesser sheen. Semi-gloss is also suitable for rooms with high humidity (best used for children's room) and can be used for trim works and casings. These paints ensure maximum durability.
CONCLUSION. Once again go through the images and the story of the painting. Was your first impression different from what you see now? Take a 5-minute online test to explore your preferences in fine arts. In 5 minutes you will confidently say "I prefer impressionist cityscapes", or "This room calls for a color field painting", "I need to have an art nouveau nude in my bedroom" - and you will know what you are talking about!
Once you figure out which position is prime and which position is spray, place the valve in the prime position and grab the primer hose. Point the primer hose in the empty bucket near the top and at an aproxx.45 degree angle from the side (the reason for this is that there is likely to be pressure still built up in the airless and when you first switch on the airless to prime it, paint will likely burst out of the primer hose and you don't want to have it go everywhere). Now turn the airless paint sprayer on and you will see that the airless is sucking up the new paint and pumping out the primer hose. At first you will typically see a cleaning solution come out followed by your paint. When you see your paint coming out switch over the primer valve to the other position and you will see the airless pumping paint into the main hose.
So lets start with Warm and Cool. When thinking about Warm, think about a desert panorama of gold, brown and earth tones. When thinking about Cool think of colors in the artic such as gray, black, white or think of the deep blue sea such as deep blues, blue greens and turquoise. Everyone can wear just about any color, the difference is in the shade of the color. When thinking of clothing, makeup or accessories, visualize Cool as a color with a drop of silvery-blue. Visualize Warm as a color with a drop of gold. For example, if you put a drop of gold to a red sweater it becomes a Warm red, but if you put a drop of silvery blue it becomes a Cool red.
Satinwood or semi-gloss - These paints are commonly used on woodwork, such as skirting boards. This sheen level is between eggshell and gloss.
