At some point or another a homeowner may be faced with the task of plastering concrete walls to change the appearance of the wall, make it resistant to moisture, eliminate unsightly cracking, or to add texture. Plastering kitchen, bathroom or concrete living room walls is easy and the finished wall will be able to withstand abrasion.

Follow these instructions to plaster the concrete walls in your home.

Step 1 - Prepare Your Concrete Walls

Before you begin to plaster your concrete walls you need to remove peeling paint and flaking bits of old plaster. Your walls should be free of paint, oil, and dust so the plaster can bond properly.

Caulk cracks and kill any mold on the walls. Use a wire brush to clean stains left by the mold or mortar joints.

Step 2 - Apply a Layer of Dash

The texture of the concrete walls should be sufficiently rough so the plaster will adhere to it. To help achieve this, you need to make dash by mixing one part cement...

Acid Stain Walk-Off Acid Stain Close Up

In this article we will talk about the do’s and don’ts of acid stain and polished concrete:

Decorative Concrete

Decorative concrete is truly flourishing and seems to be here to stay. Millions of feet of acid staining are done a year and most people (even in the industry) don’t understand the process. They recommend “sample” and “test.” I hope this article does better than that for you. Acid staining concrete has a place in decorative concrete…that is if the industry is not ruined by misunderstanding the product and what is required of the concrete substrate so it will accept acid stain properly. As with all social transitions or advances in technology, there is some catching up to do as the new transition or technology is adopted by a wider segment of the population. Green and sustainable architecture is being widely adapted.

Ugh, what have we started?

With two bowsers and allergens abounding in Austin, for sinus survival, our wall-to-wall Berber had to go. We didn’t have the $ resources to hire a crew to de-carpet the house, so my husband & I decided to wing it ourselves. Our ultimate goal was to end up with shiny concrete floors that wouldn’t hug pollen and spores and who knows what else. We did it! Here’s the play-by-play:

The scope of our project:
The entire main floor of Casa Przybylinski (other than kitchen & bathroom) was carpeted with allergen hugging Berber loops when we purchased the home in 2004. By 2006, having mustered my way through 3 sinus surgeries, my husband & I knew the Berber had to go.

General budget?:
After paying over $20,000 out of pocket for medical bills that our insurance carrier chalked up to deductibles, our general budget was merely a piggy bank. Piggy squealed when we peeked at wood, laminate or tile floors. Even getting a contractor to do...

Many municipal and even some well water sources have iron as a contaminant. It can cause rust marks in the bathtub or toilet, and it can stain your pool.

First, what type of pool do you have? There are two types of pool surfaces that are susceptible to rust and staining: plaster pools and vinyl pools.

Types of Pool Surfaces Susceptible to Staining

Plaster pools are common among older swimming pools. With a plaster pool, you can expect to get a good five to seven years out of the plaster before you need to refinish it.

Plaster was, and still is, the most common type of finish. Essentially, a plaster pool is what many refer to as a concrete pool. The finish is a mixture of cement and water. Plaster finishes are more likely to stain because the surface of the finish is porous. While the finish appears smooth, it is not. This means two things: grime can seep in and become difficult to remove, and overtime, the plaster begins to chip away and erode. This...

Janine Bjornson is a natural builder, practitioner and educator. She began her career in natural building when she trained with The Cob Cottage in 1996. Since then, she has taught over 65 workshops in Canada and the United States, from east to west. Her passion for building with natural materials bloomed out of her love for the earth, in conjunction with her concern for diminishing ecological resources and toxic buildings. As a result of this, Janine has devoted the last 14 years to immersing herself in the world of natural materials and the knowledge of how we can shape dwellings that are healthy, healing, inspiring, and beautiful. She has developed a penchant for natural paints, and plasters and loves the concept of “naturalizing” any kind of home. She loves to share this knowledge with others and this is evident in her enthusiastic teaching style. Janine has assisted in organizing 2 Natural Building Colloquia. She has presented at the Natural Building Colloquium in...

Iron Sulfate is the cheapest and probably also the least toxic concrete stain ingredient. You don't even need any acid for this stain. Iron sulfate is also known as "Copperas" and is sold for the purpose of helping yellowed plants regain a dark green color. A four-pound bag of "Hi-Yield" brand Copperas costs about 5 dollars. I purchased one of the bags below at Ace Hardware and the other at a plant nursery.


Mix the iron sulfate into the water in a non-metal bowl. The light yellow powder will dissolve yielding a tan colored solution. Do not mix the solution far in advance of when you want to use it because, over time, rust particles will precipitate out of solution.


The solution was brushed onto 10 square feet of clean gray concrete.

The iron sulfate solution gradually turns rust colored as it is exposed to air. It dries to a nice orange...

Currently, per the building code, a portland cement plaster is only required to have a weather resistant barrier (WRB) behind it, which is satisfied by the ICF; hence, building paper would not necessarily be required. However, in an insulating concrete forms-stucco installation, the paper’s primary function is to serve as a bond breaker and not as a weather resistant barrier between stucco and insulation, which have significantly different rates of expansion and contraction due to changes in temperature and moisture condition. Therefore, best practice indicates isolating the two materials from each other to allow independent movement and reduce stresses that might otherwise lead to cracking in the plaster layer. By using a permeable paper, the permeability of the wall system remains unchanged.

If it is desired to apply a finish directly to the foam form, an exterior insulation and finish system (EIFS) material may be considered. These finishes are thin, lightweight,...

Pool stains – yuck! Everyone wants their pool to be without stains. But sometimes those hard-to-remove spots and stains can take a bit more than just brushing. Here’s how you can treat and prevent unsightly swimming pool stains.

The first step to getting rid of those eyesore spots is to diagnose the stain type. Swimming pool stains can be caused by metals in the pool water, rust coming through the wall or by any organic material. The first clue to identifying the type of pool stain is the color of the stain.

A greenish-brown colored pool stain is generally due to something organic – such as leaves or mud sitting in the bottom of the pool over the winter. Algae, worms or other dead animals can also leave an ugly stain on your pool surfaces.

Pool stains that look reddish-brown, are very dark in color, or have a rust-like appearance to them are likely caused by metals. Copper stains in a pool will normally form blue, green, or black stains, while iron may...

Remove metal stains with ascorbic acid.

Minerals respond best to chemicals, and if you believe your stain is related to metals, or if the suggestions above for organic pool stains do not improve your stain, try ascorbic acid based pool products. If you want to try an easy and effective home method, crush up vitamin C tablets, and rub them against the stain. After a few minutes, check to see if it begins to lighten.


Keep in mind that ascorbic acid is best for treating iron stains, while citric acid is best for treating copper stains.

Treat large stains by adding ascorbic acid to the pool water by sprinkling it evenly over the surface of the water. Start by using a 1/2 pound of ascorbic acid per 10,000 gallons of water in the pool. Set the filter on "circulate" and turn it on. Allow the ascorbic acid to work for a half-hour. Check the pool to see if the stains are gone. If they're still there, add more ascorbic acid, and let the filter circulate the treatment for...

When your pool and backyard is as post card pretty as this pool, the last thing you want are stains on your pool’s vinyl liner.

Above ground or inground pools both use vinyl liners, and are susceptible to staining from minerals, organic materials and chemical damage.

For all of you vinyl liner pool owners, here’s how to identify, treat and prevent staining of your vinyl liner pool.


One advantage of vinyl pool liners is that the slick surface often reduces mineral staining. It’s not uncommon to see the pool stains more pronounced on plastic and metal items in the pool, such as on your ladders, steps and pool lights.

Vinyl liners also can stain in localized areas or spread throughout the pool surfaces. It can be just one small spot or only at the waterline, on on the pool steps. Size, color, location and any “behavior” of the pool stain can be helpful in identifying the source or cause of the...
