Dirt Pickup: Accumulation of dirt, dust particles and/or other debris on the paint film; may resemble mildew.
Use of a low quality paint, especially lower grades of satin or semigloss.
Soil splashing onto siding.
Air pollution, car exhaust and flying dust collecting on house body and horizontal trim.
Wash off all surface dirt before priming and painting. If unsure whether the problem is dirt or mildew, conduct a simple spot-test (see Mildew). Clean off dirt with a scrub brush and detergent solution, followed by a thorough rinsing with a garden hose. Heavier dirt accumulations may require the use of a power washer.
While dirt pickup can’t be eliminated entirely, top quality exterior latex paints typically offer superior dirt pickup resistance and washability. Also, higher gloss paints are more resistant to dirt pickup than flat paints, which are more porous and can more easily entrap dirt.
Painting tips & tricks
Rub petroleum jelly on the hinges and door knobs before you start to paint a door. If you get paint on them, they will wipe off easily.
To keep white paint from yellowing, add 2 drops of black paint to each Gallon of white.
When painting ceilings, cut a child’s rubber ball in half and put your paint brush in one of the halves to catch the drips.
An old pair of swimming goggles will protect your eyes from paint splatters and drips when painting ceilings.
When painting, protect your hands and face with moisturizer. Cleanup will be easier and the moisturizer will prevent paint from seeping into the pores.
To stop paint from dripping, punch a few holes in the rim of the paint can. When the brush is wiped against the edge, the paint flows back into the can. The lid covers the holes so the paint won’t dry out.
Before pouring paint from a can, cover the rim with masking tape. After pouring, remove the tape — the rim will be clean and the cover will fit tightly.
To remove lumps from paint: Cut a piece of screen to fit the inside of the paint can. Set it on top of the paint and let it float down to the bottom of the can. It will take all the lumps with it, trapping them at the bottom of the can.
When painting a room, dip a small card into the paint so that you have the exact colour with you and can match accessories in store.
When painting inside corners, trim the paint brush bristles to a V to save strokes and spread paint more easily.
When you poke a paint brush into corners or allow it to rest on the bottom of the paint can, the bristles curl and stray. To straighten natural bristles (not synthetics), try wrapping the brush in a couple of thicknesses of damp cloth and press gently with an iron. The steam and cloth binding do the job. Only light pressure is needed. Let the bristles cool before you unwrap the brush.
When painting old woodwork fill in the holes or cracks with a mixture of flour and some of the paint you are using. It hardens like cement and matches perfectly.
