Preparing concrete for painting or staining

Raw Concrete up to 5 Years Old

1. Wash with Muriatic Acid 2/3 water, 1/3 acid.

(Caution: Add acid to water not water to acid. Wear safety clothing and rubber gloves.)

2. Puddle out on surface and spread with broom. Allow to sit for 5 to 15 minutes. A foaming action will occur.

3. Scrub with stiff bristle brush.

4. Rinse well with hose.

5. Note: do not do this project in bright hot sunshine.

6. Apply concrete stain or clear solvent based concrete sealer (penetrating type).


1: Wash with Bio-Wash Simple Wash available at most building supply stores.

2. Follow steps 2 thru 6 as above.

Previously painted or stained concrete

1. Sand surface using large pad sander available at most rental outlets or building supply stores (coarse grit).

2. Wash with T.S.P General Household Cleaner and rinse well.

3. Follow steps 2 thru 6 as above.

4. Apply concrete stain or epoxy concrete paint.

5. Where car tires are resting, place rubber matting.

How to Preparing Woodwork for Painting

Prepping woodwork for painting isn’t difficult, but wood trim and other details can have lots of little hills and valleys. You’ll need to clean, patch, and sand the woodwork before you can paint it, so a little patience is needed to make sure the job comes out looking great. Liquid deglossers work well for prepping glossy surfaces such as enamel paints, but pay attention to the manufacturer’s instructions – the deglosser can’t be left on too long.

1. To start, wash the woodwork with TSP solution or a phosphate-free substitute, and then rinse it thoroughly. Be sure to wear protective gloves and safety gear when using harsh cleaners and chemicals. Scrape away any peeling or loose paint. If your woodwork is badly chipped, it’s probably best to remove the old finish entirely by sanding it or stripping it.


2. Use a putty knife to press some latex wood patch or spackling compound into any nail holes, dents, or other scratches. Colored wood patch material also can be used. Let the putty dry thoroughly.



3. Sand the surfaces with 150-grit sandpaper until they are smooth to the touch. Wipe the woodwork with a tack cloth before priming and painting.

Poor Sheen Uniformity Interior Paint Solution

Poor Sheen Uniformity: Shiny spots or dull spots (also known as “flashing”) on a painted surface; uneven gloss.

Possible Causes:

Uneven spread rate.

Failure to properly prime a porous surface, or surface with varying degrees of porosity.
Poor application resulting in lapping ( see Lapping )


New substrates should be primed/sealed before applying the top coat to ensure a uniformly porous surface. Without the use of a primer or sealer, a second coat of paint will more likely be needed. Make sure to apply paint from “wet to dry” to prevent lapping. Often, applying an additional coat will even out sheen irregularities.

Eccentricities Fill a London Flat.

As with all good homes, a tour of this one-bedroom flat in East London is like walking inside the mind of its owner. Lego, typographic prints, Barbie dolls, taxidermy, train station signs and a giant teacup all sit under the same roof. It’s an eclectic mix, but owner Tom Chalet makes it work.

What’s even more impressive is that he did most of it by himself. “People don’t often think of me as the DIY type,” he says, “but it was pretty easy to do all of this alone. For one thing I had no budget, so I just decorated as I went along, using bits and pieces I’ve gathered over the past four years.”

Poor Scrub Resistance Interior Paint Solution

Poor Scrub Resistance: Wearing away or removal of the paint film when scrubbed with a brush, sponge or cloth.

Possible Causes:

Choosing the wrong sheen for the area.

Use of a lower quality paint.

Use of an overly aggressive scrub medium “see Burnishing.”
Inadequate dry time allowed after application of the paint before washing it.


Areas that need frequent cleaning require a high quality paint formulated to provide such performance. High traffic areas may require a semi gloss or gloss paint rather than a flat paint to provide good scrub resistance. Allow adequate dry time, as scrub resistance will not fully develop until the paint is thoroughly cured. Typically, this will be one week. Try washing the painted surface with the least abrasive material and mildest detergent first.

Poor Hiding Interior Paint Solution

Poor Hiding: Failure of dried paint to obscure or “hide” the surface to which it is applied.

Possible Causes:

Use of a low quality paint.

Use of low quality tools-wrong roller cover.

Use of an improper combination of tinting base and tinting color.

Poor flow and leveling (see Poor Flow-Leveling).

Use of a paint that is much lighter in color than the substrate, or that primarily contains low-hiding organic pigments.

Application of paint at a higher spread rate than recommended.


If the substrate is significantly darker or is a patterned wallpaper, it should be primed before applying a top coat. Use a top quality paint for better hiding and flow. Use quality tools; use the recommended roller nap, if rolling. Follow manufacturer’s recommendation on spread rate; if using tinted paint, use the correct tinting base. Where a low-hiding organic color must be used, apply a primer first.

Poor Gloss Retention Exterior Paint Solution

Poor Gloss Retention: Deterioration of the paint film, resulting in excessive or rapid loss of luster of the top coat.

Possible Causes:

Use of an interior paint outdoors.

Use of a lower quality paint.

Use of a gloss alkyd or oil-based paint in areas of direct sunlight.


Direct sunshine can degrade the binder and pigment of a paint, causing it to chalk and lose its gloss. While all types of paint will lose some degree of luster over time, lower quality paints will generally lose gloss much earlier than better grades. The binder in top quality acrylic latex paint is especially resistant to UV radiation, while oil and alkyd binders actually absorb the radiation, causing the binders to break down. Surface preparation for a coating showing poor gloss retention should be similar to that used in chalking surfaces see Chalking.

Poor Galvanized Metal Adhesion Exterior Paint Solution

Poor Galvanized Metal Adhesion: Paint that has lost its adhesion to a galvanized metal substrate.

Possible Causes:

Improper surface preparation, such as inadequate rust removal.

Failure to apply a primer before application of an oil-based or vinyl latex paint.

Failure to sand baked-on enamel finishes or glossy surfaces before painting.


Any rust on the metal should be removed with a wire brush; then, an acrylic latex corrosion-resistant primer should be applied (one coat is usually sufficient). New or previously painted galvanized metal that is completely rust-free can be painted with a top quality acrylic latex paint without applying a primer; however, a metal primer should always be applied to unpainted galvanized metal before applying an oil-based or vinyl latex top coat.

An Oregon Cottage With 21 Flavors of Color.

Eric and Mimi Kauffman’s 1912 cottage in Oregon is a bold reflection of their zest for life, cuisine and comfort. Bright colors and a verdant garden invite those strolling by to linger and enjoy the wonderful aroma from the kitchen window.

The couple spent the first few decades of their marriage traveling far and wide, guided by their bohemian spirits. When it came time to put down roots, they chose Halfway, Oregon, nestled in Pine Valley near the spectacular Wallowa-Whitman National Forest. Halfway is also the gateway to Hell’s Canyon and the Snake River. This town, with a population of 350, is known for ranching, outdoor recreation and, above all, hospitality.
