What is concrete engraving?
The concrete engraving process consists of several combined methods in which the concrete floor or wall is colored and carved (engraved) to achieve a beautiful transformation from dull gray to fantastic color(s) and design(s). A penetrating water-based or chemical stain is used to color the surface before a precise pattern is permanently engraved (cut) INTO the concrete with a patented machine utilizing various diamond blades for straight and radius patterns, or various patented engraving tools for intricate designs. The process is completed with the application of a clear top coat to seal the surface area.
How long will an engraving job usually last?
Engraved bricks, tiles or designed patterns will never come loose. The design is cut into the concrete rather than through it. Weeds and grass will not grow between pieces of the design. The design will last as long as the concrete because it IS the concrete.
Where possible can staining and engraving be applied?
Staining and engraving can be achieved almost anywhere that there is concrete. Of course if the surface is beyond recovery, reconsideration is warranted.
Should existing cracks be repaired beforehand?
Most cracks as well as chipping, if not too large, may be disguised with little or no repair. In most cases, when the stain is applied and the engraving is complete, most minor cracks are not that noticeable. Extensive concrete damage may require repair or replacement before engraving.
How long after new concrete is placed can staining and engraving be applied?
Usually 30 days.
In what way does concrete need to be prepared for staining/engraving?
The concrete MUST be first cleaned with a high pressure washer if outside and chemically and/or mechanically prepared if inside. If previously sealed, the existing sealer has to be removed. Oil and paint stains are treated and removed as much as possible. In some cases the surface is sanded to accept stain. Depending on the type used, the stain may need to be neutralized and power washed again.
Can concrete that has existing glue, paint or oil stains have a color stain or engraving applied?
Yes, some residual discoloration may remain. Often after a thorough cleaning, the darker spot(s) are disguisable in the design by various means. Costs may be greater due to the extra labor and cleaning agents for removing such items.
Can a concrete surface with a poor finish accept staining or engraving?
Yes, depending on how poor the surface is, it may require surface grinding for the desired finish. This may expose the aggregate depending upon the depth of grinding. While at times an undesirable occurance, it can also add to the appearance. Grinding, if needed, will add to project cost.
If a section of a previous design has to be duplicated due to concrete removal, is it possible to match the remaining colors and the pattern?
Patterns and designs can be matched and colors may be tinted to match very closely.
Can select portions of a concrete surface be stained and engraved?
Yes, in many instances a separation of design or fade in color is more pleasing.
How do weather conditions affect staining/engraving/sealing?
The concrete surface temperature needs to be between 40 and 100 degrees Fahrenheit for stain and sealer application. It is highly recommended that the surface be dry during the engraving process and completely dry for sealer application.
How thick is it?
No thickness is added at all. The engraving cuts into the concrete to give the appearance of a grout line or a mortar joint, giving the surface dimension without any need for material build up.
How long does it take to complete the staining/engraving process?
Relatively the same as many other flooring methods. A concrete staining and/or engraving process may take several days to complete depending on the size of the project, accessibility, as well as weather conditions. The cleaning and preparation of the concrete surface is of utmost importance to the longevity of the finishes. All areas should remain clean and uncontaminated until dry. In some cases a particular stain may be applied on damp concrete. Sealers can not. The stain and sealer applications must be protected from contamination and surface contact during all steps of the process. The project area(s) should be blocked or roped off during each stage of application to ensure proper adhesion of each coating. Staining/sealing areas must be avoided during the process and should not be used until the coatings are completely cured. Occupation availability times are contingent upon specific weather conditions. In most cases a 24 to 72 hour waiting period is required after the final finish is applied.
What does the coloring or staining as well as the sealing do?
The stain permanently penetrates the concrete surface and becomes a colored sealant promoting longevity. Stain applications react with the concrete producing various natural tones and hues. Other stains can give a tint or opacity to concrete surfaces. Depending upon the choice of sealer used for the appropriate project parameters, a sealer can repel or resist certain types of spills. It is best to wipe up any spill ASAP because prolonged contact could be detrimental to the finish as some chemicals are more corrosive than others.
What happens if the concrete becomes scratched, or chipped deeper than the stain?
Scratches/chips can be repaired, touched-up or both. A list of stain(s), as well as dilution ratio and sealer type is on record for each project completed. A copy is available upon request.
How many colors are available?
There is a nearly unlimited spectrum of colors. A multitude of manufacturers, all with varying color palettes are available. Typically, just about any color is available or can be mixed to achieve a desired color.
How many colors are possible on the same engraving?
There is no limit. Many colors compliment others.
Do applied colors/stains match those in catalogs or displays?
No. All concrete surfaces stain differently due to many variables, including but not limited to age, mix specification, aggregate, etc. Different dilutions or multiple applications of colors can usually achieve an acceptable match.
Will colors fade with time?
Sometimes colors may get a bit darker. Some will fade under UV rays but overall there will be very little noticable change. Periodic maintenance is helpful in reducing these effects.
How many designs are available?
Designs are as limited as the imagination in most cases. There are many standard design templates available. You can also provide a design or collaborate with Concrete Colorscapes. Templates can be created from these original concepts and used to precisely engrave the design into the concrete surface.
How deep are the engraving cuts?
Generally 1/16" to 1/8" deep. Deeper cuts are possible but usually not necessary. Usually just enough depth to simulate a grout line or mortar joint. Various widths are available.
What will an engraving job look like in several years?
With periodic maintenance using a sacrificial floor finish, any design will look substantially the same for many years after application. Without maintenance over time, engraved brick, stone or tile patterns will take on an antiquated or weathered appearance. Many consumers find this to be a very desirable look.
What maintenance does a completed stained/engraved job require?
A completed project is very low maintenance. Ideally, outside all you need is to wash it down periodically with a garden hose. Inside, a wet mop is all that is required to keep the surface clean and free of abrasives. A sacrificial floor finish, much like a department or grocery store uses, is recommended as well. Quality floor finishes emulsify with the existing floor finish so usually no stripping is needed.
How much will a staining and engraving project cost?
Obviously, a complete job cost relies upon concrete condition, total square footage, accessibility, design parameters and sealer choices. Generally, engraving is very competitive with other types of flooring such as tile, stone, brick pavers, wood and overlays. In most cases it is less expensive.
Is there a guarantee on staining/engraving?
The engraved concrete carries a guarantee for the life of the concrete, excluding negligence or deliberate damage. As long as the concrete was in good condition beforehand, the engraving will remain.
