Proline Dura-Color hardeners

DESCRIPTION AND BASIC USE: Proline DURA-COLOR HARDENER is a colored dry-shake hardener that is broadcast by hand over the top of freshly placed concrete and worked in with a wood float to form a dense, colored concrete ‘skin’ on the slab. Dry-shake color hardener is best applied to a concrete slab containing no more than a 4 inch slump and between a 5 and 6 sack per cubic yard cement content. This product is compatible with most admixtures, but avoid those containing calcium chloride. Apply Proline DURA-COLOR HARDENER shortly after screeding and floating the new concrete just as the bleed water is coming to the slab surface. It should be broadcast by hand as uniformly as possible and then worked in with a wood float. Start with the edges first then work in toward the middle when broadcasting and floating. Most colors will go on with two shakes, or coats, followed by touch up but lighter colors may require three shakes. If the surface is to be textured, then a light troweling is recommended. Over-troweling will discolor the concrete. For a textured ‘antique’ look, a light hardener color should be paired with a darker Proline DURA ANTIQUE RELEASE and Proline TEXTURE MATS for stamping. It is always recommended that a representative job site sample be done to test the look of the color and texture combinations.

BENEFITS: Proline DURA-COLOR HARDENER is formulated with only quality ingredients for a denser, more durable surface. The denser surface will pick up even more details from the texture mat. DURA-COLOR HARDENER is made with U.V. resistant, alkali-friendly, iron oxide pigments and it’s blended in a carefully monitored process for maximum consistency. COVERAGE: One 60 pound bucket of Proline DURA-COLOR HARDENER covers about 100 square feet.

SEALING AND MAINTENANCE: A quality Proline sealer is recommended to protect the newly colored concrete surface. The concrete must be cleaned and thoroughly dried prior to application. Proline provides sealing products such as, DURA -SEAL HG (High Gloss finish) and DURA-SEAL MATTE (Matte finish), which are solvent-based acrylic clear sealers. Inspect annually for areas of thin or traffic-worn sealer and re-apply as necessary. Standard cleaning practices for colored concrete should be followed; schedule periodic cleaning to avoid accumulation of dirt, flatwork and floors are easily maintained by sweeping, clean spills when they occur, hose off dirt with water, and treat heavily soiled areas by wet mopping and/or scrubbing with a properly diluted, high-quality commercial grade detergent.

NOTES: Experimentation of colors and application methods is recommended, as the color of the actual product may differ. Test sections must be produced on each concrete surface. Even in a controlled environment, cements, aggregates, water content, and concrete curing methods will contribute to different results. Final color approval should be made with actual material and sealer selection; however, variation of even mock-up samples due to reproduction limitations should be expected.

COVERAGE: One 60 pound bucket of PROLINE DURA COLOR HARDENER covers about 100 square feet, but lighter colors may require a rate of 100 pounds per 100 square feet

CURING: Non-staining acrylic, wax curing compound, or sealer is recommended. Do not cure with plastic sheeting, membrane paper, or water misting. Avoid sodium silicone type hardeners. Products not recommended could cause discoloration or mottling of the colored surface. Allow the concrete to cure for 28 days before sealing.
