Your contractor will sweep or scrub the concrete first with a dry brush, and then clean it thoroughly with trisodium phosphate (TSP) and warm water, then let it dry. TSP is a mostly alkaline solution that does a great job cleaning grease and oil off concrete surfaces. Brush painting concrete siding costs $138 per 100 sq. ft., roll painting costs $50 per 100 sq. ft., and spray painting $32 per 100 sq. ft. Louisville House Painting
Painting a straight line, also called cutting in a line, is another painting technique worth mastering (Photos 7 – 9). Begin by removing excess paint from the brush either by laying it off onto the piece you’re painting or by wiping it on the edge of the can. Then, holding the brush like a pencil with the bristles edgewise (Photo 8), draw down along the line. If too much paint begins to build up under the bristles, threatening to spill across the line, sweep the brush away from the line. Then go back up to the top of the stroke and draw down again, moving the paint closer to the line. Continue this process until you’ve cut in the entire line.
Turn the brush to paint the adjacent edge of the same inside corner and repeat the process. Reload the brush and remove excess paint from the bristles by laying on the paint close to, but not against, the edge you’re cutting in. Without reloading the brush, go back and paint close to the edge. Fan the bristles slightly and use a slow, steady stroke while concentrating on the line you’re painting. Complete the exterior house painting job by smoothing the paint in the center of the panel with long, sweeping strokes, keeping well away from the completed edge. House Painting Louisville Colorado
