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.
Remember, you will need to clean the airless in that same fashion before you return the airless back to the rental company.
Is some color dominating?
If you have a timber floor that's not particularly attractive or is made from a patchwork of old and new wood, paint makes the perfect disguise. There are plenty of choices - all the colours from Farrow & Ball are available as floor paint and Nordic Style offers an elegant selection, too.
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.
Now is the time to paint the exterior of your home. It is best to start painting on the sunny side of your home first and the reason for that is because it's likely there is still dew on the shaded side of your home in the morning. Tip: Your house must be perfectly dry in order to start painting.
Cutting Down on Paint Chemicals. Everyone knows the nasty smell of paint drying - worse with oil-based paints, but also noticeable with vinyl emulsions. This is caused by paint solvents containing VOCs. They are proven health risks, and can cause allergies, headaches and breathing problems and irritate eyes, nose and throat. They are also an environmental hazard.
