Painting Doors And Trim – part 3
Painting Interior Brick
1 SCRUB THOROUGHLY WITH A TSP SOLUTION and a brush with firm, synthetic bristles. Wear goggles and protective gloves. Rinse at least twice. TSP is a suds-free cleanser; you may not see residue, but it will interfere with adhesion. Allow the surface to dry thoroughly.
2 REPAIR JOINTS WITH THINSET MORTAR AND A SMALL TROWEL, called a tuck pointer. Brush wet mortar off bricks with a stiff brush as you go. For a finished edge, smooth joints and corners with a tool called a jointer or with a copper pipe, as shown here. Allow to dry completely. Mask adjacent surfaces with painter's tape. Spread drop cloths to keep paint spatter off adjacent surfaces.
3 APPLY A LATEX PRIMER SPECIALLY FORMULATED FOR BRICK, masonry, and stucco using a roller with a 1-inch nap. Let the primer dry and roll on a semigloss or gloss latex paint. Touch up corners, cracks, and crevices with a 1-inch brush.
Painting Interior Concrete
1 TEST FOR MOISTURE IN OR UNDER THE CONCRETE BY TAPING A 4’ x 4’ V POLY SHEET OVER THE FLOOR FOR 2A HOURS. If the sheet is damp or wet, there is too much moisture seeping through the concrete. Leave the surface unpainted. The moisture would cause the paint to blister. If the sheet is dry, proceed to step 2.
2 SPRAY THE SLAB WITH WATER. If the water beads, scrub with a TSP solution to remove any grease; rinse and test again. If the water still beads, then scrub with a degreaser/concrete cleaner. Once the concrete is clean, etch it with a solution recommended by the manufacturer of your chosen paint. Follow its safety recommendations carefully. Rinse thoroughly. Cleaners may react with the paint or interfere with paint adhesion.
3 APPLY A CONCRETE PAINT USING A 9-INCH ROLLER WITH A %-INCH NAP. Let the paint dry and apply a second coat. Use a paint formulated to withstand hot-tire pickup, such as one-part epoxy, acrylic garage floor paint. Two-part epoxy is also available for particularly tough jobs. [Avoid using porch and floor enamel or ordinary epoxy on a garage floor: Hot tires will stick to it and lift it.)
Paint is made of materials that are good for the wall but bad for the water and plants and animals. Due to studies showing the toxid effects of paint, clean-up methods have changed. The basics remain the same—clean up latex paint with water and alkyd paint with mineral spirits. The goal is to use as little of either as possible, and then to dispose of them wisely.
BASIC CLEAN UP
• Put as much paint as possible from rollers, brushes, and trays back into the paint cans. Begin by scraping the roller with the round section of a painter’s 5-in-l or 6-in-l tool; scrape a brush with the flat end of the tool. Then put brushes and rollers on a brush and roller spinner, insert the roller inside a waste container, and spin. Let the paint dry and toss the container.
• Wash brushes and roller covers in as little water or mineral spirits as possible. Wash brushes or rollers where the liquids will not go down a drain. They pollute the water; even nontoxic solids inhibit aquatic life.
• When washing more than one roller tray, pour the water or mineral spirits from the clean tray into another tray to be washed.
• Place the water or mineral spirits used for cleaning into a covered 5-gallon (or larger) bucket, and let the solids settle. What you do next depends on whether the paint is latex or alkyd.
DISPOSAL OF LATEX WASH WATER AND WASTE
• According to the EPA you should “dispose of wastewater by tipping it onto a flat, grassy area or area of soil that can retain the liquid; put it in a place where it won’t run into any sewer, storm water drain, or natural waterway.”
• Seal the solid wastes in a can and put the can out for a trash disposal service or take it to a licensed landfill.
DISPOSAL OF ALKYD WASTE
• Once the solids settle, pour the liquids into a sealable container. You will be able to use them next time you need to clean up alkyd-covered brushes, rollers, and pans.
• Seal the solid wastes in a can and put the can out for a trash disposal service that will take it to a licensed landfill.
• If the liquids are too old or too paint-laden to use again, do not dump them on the ground or pour them down the drain. Do not let the solvents evaporate and throw out the remaining solids. Solvents are prime sources of volatile organic compounds and are strictly regulated. Find a solvent recovery depot and take the solvents there for proper disposal.
Since requirements vary, always check with local authorities for approved disposal methods.
SAFE CLEANING - This 4-step process is one of the best ways to clean brushes; it's also environmentally friendly and cuts down on solvent use.
1 Half fill each of three cans with water (for latex paints) or paint thinner (for oil-based paints).
2 Clean the brush in the first can by moving it up, down, and sideways to remove most of the paint.
3 Repeat the process in can #2, and then again in can #3.
4 Dry the brush by slapping the ferrule on the heel of your hand, then pressing the bristles between newspaper or paper towels. Put the brush in its original cardboard holder to help it keep its shape. Hang it vertically to dry.
Allow the solids to settle into the bottom of the cans. Pour the thinner or water into clean cans for reuse. After the solids have dried, toss them.
