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. You scuff up existing paint for two reasons. First, you want to get rid of any oil, grease or dirt trapped in the top layer of paint. This is the stuff that cleaners and degreasers can't get off. The second reason to scuff is to set up a physical bond for the new primer and paint to adhere to. You want to give the old paint some tooth so the new sticks better. Like this, it will actually take quite a while to reach a number that is close enough to the yellow color you've chosen that you can't tell any difference (and mathematically, you will never actually reach an average of 4!)
Preparation, the key to a successful paint job is to take the correct steps when preparing the job. Preparation for this article, has two parts, the first part is wall prep. The walls you are going to paint may have nail holes or imperfections that need to be filled before you paint. The proper way to fill them, if they are smaller is with water putty, by simply forcing a little bit of the putty in the hole and breaking it off flush with the surface. For larger depressions, use a drywall compound or spackle, which may require a second application to fully fill the indentation and make the repair/"patch" flush with the wall. When it comes to makeup, the best eye pencil colors are in the shades of brown to brown-black espresso. To bring attention to your eyes, wear eye shadows in medium shades of copper, medium olive green and medium to dark brown. For instant goddess glow, use blush colors anywhere from terracotta to deep tones of salmon. Let your lips look fuller with shades of cinnamon, peach and terracotta. Finally, let your lashes look fuller with brown or black brown mascara. Special paints have been innovated from different consumer insights and brilliant paint technology that allows specific paints for specific needs. If you have large holes or cracks in a wall purchase a small can of vinyl repair paste. The reason I prefer it over regular wall Spackle is that after it dries it is much harder and sands easily. You can even use it for minor wood repair in a pinch.
