Mary and I had the good fortune to ask David several questions we believe you may have regarding staining concrete.
correcting mistakes is not easy, we thought it best to learn from the experts.
Staining Concrete Floor Basics - Interview with David Goddard
David, what factors should be considered when staining new porch concrete flooring, such as
surface texture and color considerations? Anything different to take into account for
older concrete flooring?
Most exterior concrete patios, walkways and driveways can be stained regardless of age.
However, a general rule of thumb is that the newer the concrete the more vibrant the colors will
be. This isn't always the case though since there are techniques and methods available to clean
and even restore older concrete surfaces.
As long as the concrete surface is intact, not previously treated with a sealer and free
from other chemical spills/imperfections, then you can enjoy stain to its full potential.
Color options generally vary and depend on the region you live in.
Here in the mid-west, earth-tone colors are popular since most homes are constructed with some degree of those
red, browns and tans (brick, stucco, siding, etc).
This was a beautiful sunroom that David worked on a few years ago. Cola and Vintage Umber were the colors
chosen and he couldn't have been more pleased with the outcome.
Exterior concrete in most cases are textured (broom finish, etc), and as a result acid
stain can look a little differently than staining interior concrete which is generally
smooth and texture-free. Either way, you can't go wrong with adding color to your concrete!
Staining Concrete Floor Basics - Staining Process
Briefly explain the staining process.
Acid and water-based staining is a process in which a chemical reaction takes place
between the stain, the lime and other minerals inside the concrete. Depending on the
application method, you can achieve a wide variety of results.
However, each concrete surface has its own "personality", so it is difficult to specifically predict the final
color(s) intensity and other character traits associated with the process.
Multiple colors can be skillfully used together to create a dynamic that's visually stunning!
David writes: "This was our very first custom home that we built a few years ago. We always knew we wanted
something unique for our driveway and walkway so I painstakingly created a custom design. This
beautiful pattern is so time-consuming that I haven't duplicated it on another driveway since!
However, I would certainly provide this custom design again should a client ask for it."
A high-quality sealer is needed to complete not only the staining process, but
also the final color aesthetic. For exterior surfaces, it's vital to select a
sealer that is non-yellowing and UV resistant. This will add considerable life
to your protecting top coat and provide longer protection against the elements.
Explain various staining techniques if there are several.
There are actually many staining techniques in the world of decorative concrete. Some
factors that influence this are region, trends, individual concrete artist and client
request (to name a few). One of the most common methods is spraying. This method provides
a nice conical, uniform and consistent pattern.
Brushing and ragging are also techniques to apply stain. You can achieve interesting effects
by using these, however the application time can sometimes be extended as styles such as
ragging are often done by hand.
This back patio is an example of how vibrant and stunning the overall design looks with a border,
especially if it's stained a darker color for contrast. The diamond pattern
is a timeless classic and can add elegance and style to any porch or patio.
More intricate and specialized designs are hand 'painted' with stain. Examples of these
might be custom scoring patterns that are stained a variety of colors by hand. Detailed work
such as this would make spraying or other techniques undesirable since the application cannot be controlled.
Staining Concrete Floor Basics - Designs and Patterns
How do you create designs and patterns like diamonds, checks, etc.?
Decorative scoring is a creative technique in which desired patterns and designs are cut
into the concrete surface. The depth usually averages between 1/8 inch or greater. Regardless
of which design is used, the one common denominator is math.
Figuring out where everything goes, how big they are and whether there's a need to proportion it all is part of the calculations.
Decorative scoring always starts with a little math and imagination! In most cases,
any concrete space can be scored with a beautiful design. Once the pattern is decided then
the entire design is applied to the surface using blue contractors chalk. You can then
see exactly how the overall design is going to look before cutting a single line with a saw.
Scoring is a permanent application and therefore mistakes cannot be undone! As such,
concentrating and a steady hand are essential throughout the cutting. All in all, scoring
goes hand in hand with acid staining and should be given consideration prior to deciding
which options will be chosen for the client.
Staining Concrete Floor Basics - Maintenance
How do you care for and maintain stained concrete?
Stained concrete is usually a low-maintenance affair. The sealer top coat protects the
stain underneath from water and other elements. Dirt, leaves and other exterior debris are
swept or blown off with ease.
There are a few concerns though. The first is outdoor furniture,
especially of the metal or iron-made type. A higher degree of care is essential when it comes
to exterior furniture due to the fact that dragging metal chairs across a finished surface
can damage the stained concrete (sometimes severely).
You wouldn't believe it but this floor actually used to have carpet on it! Not all concrete
slabs post-carpet are suitable for stain. In most cases this is due to the excessive amount of
glue, paint, chemical spills and other things that were spilled on the floor during construction.
Having said that, there are extensive preparation techniques that can bring an otherwise
unacceptable floor to stain readiness. In severe cases, it's best to have an overlay (skim coat)
of fresh concrete applied to the surface.
I generally tell clients to treat their stained patios (etc) like they would a blu-ray disc.
You don't want to drag metallic objects across the surface because it will scratch. A deep enough
scratch can actually penetrate through the sealer and stain thus exposing raw aggregate. Touch-ups
can often times be applied, but this doesn't always camouflage the initial damage.
The second concern is rock salt, which is obviously used to melt ice during the winter season.
Using rock salt on regular concrete is fine (although a white discoloration may
occur) but this can be very damaging to sealers. I highly recommend replacing rock salt with
kitty litter, or other non-chemical deicers.
The color (vintage umber) complements the stone fireplace and furniture.
Staining is a permanent application. The only thing not permanent is the protective sealer
top coat. That can eventually wear down or even off. In time a revitalization cost may be necessary.
The frequency will depend on traffic. Most residential households
might not need to worry about a fresh coat of sealer but once every 1-2 years or so. Clients
who entertain frequently on treated areas or commercial flooring with high traffic might need
to address this situation sooner.
Staining Concrete Floor Basics - Topcoats
What are our sheen options?
Sealers come in the luster (shiny, glossy, etc) and matte (dull, non-glossy) types. Most
applications use a sealer with some degree of gloss as this accentuates the
stain colors and final visual aesthetic. It all comes down to personal preference, but
regardless ensure that a high-quality non-yellowing UV rated sealer is being used.
Describe concrete stamping and clear coating.
Concrete stamping is only possible when a brand new patio, walkway, driveway,
etc is being poured new or when a thick enough micro-overlay (skim coat) is being
applied over an existing surface. Stamping is a very specialized technique where
rubber stencils containing various patterns are "stamped", or pressed onto the soft
The window for this application is very small, however. The surface needs to
be hard enough (set up) for the contractor(s) to carefully stand/walk on, but also
soft enough to receive the stamp imprints. Since stamping is done in sections, poor
timing and planning can be absolutely devastating, with worst case scenarios calling
for the concrete in question to be ripped out and re-poured (at the contractors expense).
Stamping is very unique in that there are many designs available to create
stunning effects on your concrete. Some designs include making surfaces look like:
Italian Slate, Marble, Hardwood Flooring, Stacked Stone, Riverbed Rock, etc.
Staining Concrete Floor Basics - Costs
Could you address average costs of staining concrete?
Pricing for decorative concrete in many cases falls into 1 of 3 categories: Price per square
foot, price per linear foot or a predetermined total. There are other exceptions, though.
As a guide only and to give you a general idea, decorative
concrete services may range from $2.00 per square foot to $15.00 per square foot depending on where you live.
Labor-intensive services will cost more. High-quality concrete overlays and stamping may fall within
the previous estimated pricing range.
A basic stain and score package, depending on location and size of the project,
can range anywhere from $2.50 per square foot on up. More complex staining or intricate
scoring designs may increase the price.
Concrete overlay systems generally start around $5.00 per square foot. This can vary significantly
depending on factors such as thickness desired, total amount of product needed and whether or not
decorative services are requested after the new overlay has been applied.
The differences between hiring a professional and doing a project yourself can have considerable
pros and cons. Those who are pressed for time and/or lack the necessary knowledge and skills to DIY
should consult a reputable professional. Many companies offer complimentary estimates as well.
This is a classic diamond pattern with a border.
The stain colors used were Vintage Umber and Black. Note the depth and dimension of the colors;
random darks and lights give any concrete surface personality and character.
Staining Concrete Floor Basics - Final Thoughts
However, prior to contacting a professional, it's advised to at least spend a little bit of time
researching the basics of how decorative concrete works, or more specifically the service(s) you're
interested in getting. This can often times be very beneficial between the client and the contractor,
especially since doing research can eliminate unreasonable expectations, concerns or anxieties
regarding the project.
For those who like to get hands-on with their home or business, doing it yourself is a double-edged
sword: On one hand you stand to save a lot of money initially on materials and other labor-related
costs, but on the other hand, if you make a mistake (or several mistakes) you can quickly go upside
down financially on the project in an attempt to correct whatever happened.
Because stain and other
decorative concrete services are semi-permanent to permanent, mistakes can have very undesirable
outcomes. Those who spend the necessary time researching and getting hands on experience stand a
greater chance of success in whatever it is you're wanting to accomplish. Be sure and follow each
and every recommended process and take your time.
This beautiful porch patio was stained with two different colors. The outcome was
completely random and stunning.
