basic formula? single color exterior labor only ranges from $0.85 to $0.95 per sq foot as a BASE starting point. Prices go up depending on multiple colors, slope of surrounding areas, multiple stories..etc.Some painters charge per window to mask off. Ive seen $25 a window to $50. Interiors without flooring can be factored the same way. When you start having to do multiple colors, cut ins, masking, room isolation...etc. the price jumps considerably. I always start with a base of $0.85 a sq foot and figure it out from there. the season plays a major role too. paint and materials are charged separatly and are typically marked up at a minimum of 15%. I always tell clients this. that way they pick the paint out they want and what quality they want as well. Anyways...thats your base. 1250 sq foot home @ .0.95 a ft = $1,187.50 (one color). Pressure washing, Add another $45-$55 per hour. a 1250 sq ft home is not going to take longer than 2-3 hours if its a single story.
Sand the trim with a fine-grit sanding sponge. Sponges get into crevices where sandpaper can’t go and let you apply even pressure. Then apply the ﬁrst coat of paint, let it dry at least 24 hours, lightly sand it again for a completely smooth surface, and apply the second coat. After each sanding, vacuum the trim, then wipe it down with a tack cloth to remove the dust.
Back to the article. You can add water to all latex based paints / thinner to oil based paint. The tinting base has absolutely nothing to do with it. Say you are working outside and throughout the day you have to add a little water to keep the same consistency. If somebody really tried to add 20% to 50% water they no longer would be painting they'd be performing a whitewash or pickle finish.
