Solomon Colors ColorFlo"  Liquid Concrete Colors are predispersed iron oxide pigments containing high pigment solids in an aqueous base liquid. The use of ColorFlo" Liquid Concrete Colors provides an easy handling, dust-free environment for integral coloring of concrete block, concrete pavers, concrete floors, plus vertical precast and poured-in-place concrete construction.

Due to shade variations associated with individual color monitors and printers, we suggest utilization of our literature request form to review an actual ColorFlo" Liquid Color Brochure. We strongly recommend that a test slab be poured and approved prior to starting the a job. Test slabs should be poured replicating job site conditions. Lower dosage of color and variations in gray cement may effect the final shade.

OVERVIEW OF BENEFITS

Convenient and accurate batch control.  Iron oxide liquid colors can be easily pumped at a measured rate to assure accurate color batching. They can also be measured by weight or volume for batching purposes.

Location flexibility. Because of its ability to pump the liquid colors, the dispensing system can be located away from the congestion of your mixers, machines and forklift equipment. Product can be pumped to second-level mixers from ground level, eliminating the need to lift heavy dry pigment to upper floors. 

Reallocation of personnel time.  Most dispensing systems are automatic and require little attention during operation. This allows you to redistribute manpower to other productive areas.

Cleaner and safer operation. There is no direct handling of dry pigment, resulting in a cleaner and safer environment. 

Inventory ease and consolidation. You only need to stock four primary liquid iron oxide colors to create hundreds of standard or custom color blends. (The color chips on the reverse side are just a sampling of liquid colors available to you.)

GENERAL GUIDELINES

Color Pigments 

• Color pigments may be added at any time after aggregates, water, and cement.

Aggregates 

• Pre-wet aggregates before adding color pigments.

• Use clean aggregates with low soluble salt content.

• Weigh all aggregates and cement accurately for each batch.

Mixing

• Mixer should be loaded to a minimum of 40% capacity to insure good color dispersion.

• DO NOT LOAD the mixer beyond the recommended capacity. OVERLOADING will reduce mixing efficiency.

• Begin each new truckload with a thoroughly cleaned mixer.

• Mix for a minimum of 10 minutes AT HIGH SPEED before pouring.

• Maintain consistent slump at or below four inches.

• Adding water to concrete during a pour, to allow for the placement of concrete in stages, should be kept to a minimum. 

Additives 

• DO NOT use calcium chloride. This product can cause discoloration in the form of light and dark areas in the finished product.

• The use of lignin in the mix will enhance color dispersion.

• The use of plasticizers and air entraining products designed for colored concrete production are acceptable.

Final Finish

• Initial floating should be discontinued as soon as the surface becomes wet. Floating may be resumed after the surface water disappears.

• The final finish such as broom, swirl, or imprinting may be completed after floating.

• Do not cover, fog or otherwise attempt to "cure" the slab at this time. Any of these actions will create uneven coloring.

• Use of a clear non-yellowing breathable UV-stable acrylic cure and seal after a minimum of 24* hours is acceptable. (In locales where high heat and low humidity conditions exist, a non-staining evaporation control and/or sealers may need to be applied sooner)

* When conditions are cool or when sub-base or concrete is overly wet, efflorescence may appear on the concrete surface as a white powder. This can be removed before sealing by scrubbing with water and a push broom, pressure washer or a mild acid solution. depending on the age of the concrete. Allow surface to dry completely before sealing.
