If the paint job on your house is in good condition and is not chalky (a chalky film comes off on your hand when wiped over the surface) then you do not need to prime it. You should wash the house to remove dirt and mildew before you paint. The finish paint will be either a satin or semi-gloss acrylic latex paint and be sure to buy the best the PAINT STORE has for the best value.
