Deco Gel Patina Stains are composed of a unique formulation of blended metallic salts, in an acidic, water – based gelled solution. These metallic salts penetrate and react with the chemical substance in concrete to deposit the colors into the pores of the concrete. Each color is composed of a complex proprietary formulation containing no pigments or resins. This formulation creates a more effective chemical reaction and deeper colorization.

Limitations:
Deco Gel Patina Stains are not to be used in order to hide or cover blemishes or errors in concrete. In certain cases, the stains may accent finishing marks or blemishes in concrete in an unpredictable manner. All the Deco Gel Patina Stains available require various times of activation in order to achieve optimal performance. Because of this, when stains are first applied, they appear different than their end result. Use the chart in the column below to reference color, required time as well as first appearance of color. Each individual concrete substrate will create different effects that may appear significantly different from the color shown on the chart. Some of the many factors include, but are not limited to: finishing technique, mix designs, curing practices, age, condition, porosity and base color of concrete.

Due to the transparent color Deco Gel Patina Stains leave on the surface of the concrete, There is an element of uncertainty and unpredictability in its final appearance, which can include uneven or molten effects. This is however not considered to be a defect, but the reason this method of coloration is chosen. In particular, our blue and green stains react to the presence of moisture and create black spots and should not be applied to a wet or damp surface. It is always strongly recommended to test the stain on the surface in an inconspicuous place.

Coverage:
Coverage will vary widely depending on the porosity, texture, application techniques, age of concrete, number of applications and various other factors. A typical gallon of Deco Gel Patina Stain will cover approximately 150 square feet.

Application & Color Effects:
There are various designs and effects achievable using the Deco Gel Patina Stain System which is why a test sample is highly recommended and nearly a necessity. When preparing the area to be stained, make sure not to perform an acid wash to clean the surface. Doing this will inhibit the Deco Gel Patina Stain and it will remove the lime necessary for reaction and optimal colorization. Experienced applicators may want to sand the surface prior to staining using a palm sander with 50 or 100 grit mesh or paper.The function this will serve is to open the pores of the concrete so staining is easier and colorization is more thorough. Surfaces must be completely dry and free of dust before application.

The application of the stain will vary according to size, design and desired effect. To apply Deco Gel Patina Stain, a foam brush or foam roller is the most common tool. Both of these items will give you a varied effect with diverse colors and hues. For a more diverse effect, use a plastic drywall trowel for application.

Deco Gel Patina Stains are typically applied with one even coat, while working the color into the surface using the above mentioned foam brush or foam roller. When you first apply the stain, you should notice a “fizzing” reaction to the concrete. This is the metallic salts and acid reacting with the concrete surface and is a sign that the surface is accepting the stain. A second coat may be applied if needed. Do not rinse the surface during or between applications, but allow the color to remain on the surface for the allocated amount of time referred in the previous column to achieve optimal results. After the stain has been applied and has sat on the surface for the amount of time allocated, you need to neutralize the surface using 1 tablespoon sodium bicarbonate per gallon of water and apply directly to the surface. This is not exact, and you can use more bicarbonate if necessary. This will neutralize the stain and give you an idea of the final color. The surface needs to be thoroughly scrubbed using soap and water if necessary to remove all residue.

After the surface is completely dry and neutralized, you can apply a sealer to protect the area and highlight your freshly stained surface. We recommend using Sprayable Satin Finish Concrete Sealer or Krystal Kote High Performance Cross-Linking Water Based Concrete Sealer. Both of these products can be applied using a foam brush, lambs wool applicator or a Padco™ “Floor Coater”. It is best to apply at least two coats of sealer to the surface to protect the finish and keep your concrete looking new for years. Sealer must be reapplied every 1 to 3 years depending on wear and weather.

Shelf Life:
The typical shelf life of our Deco Gel Patina Stains is two years from the date of purchase. Containers should always be stored out of direct sunlight, tightly closed and upright. Always rotate your inventory when storing.
