This will enable the finisher to create a denser surface paste with no obstruction due to the appearance of coarse aggregate, allowing for a uniform sand texture. Contact manufacturer’s representative for installation instructions of the flatwork finish retarder. Mock -up shall be provided as noted under 1.5 Quality Assurance.
1. Protect all curbs, borders and adjacent concrete and masonry surfaces, pavers, stones etc. that are not to receive retarder finish prior to concrete placement and retarder application using Tem-Protect.
2. Place concrete in the manner prescribed previously. Screed or strike off the surface in two (2) directions using a wooden or metal straight edge to achieve the proper elevation in a sawing motion back and forth.
3. Allow the bleed water to evaporate the surface. It can than be floated using a wooden hand float or a bull -float preferably wooden to close the surface and surround the coarse aggregate with cement paste. Float to a uniform appearance. Follow float operations with hand trowels or Fresno steel trowels to create tight dense smooth surface. (This may require two or three passes depending upon mix design and or desired finish to be achieved)
NOTE: Do not burnish the surface or allow the exposed sand surface to prematurely dry prior to the application of Optimus Flatwork Finish Retarder.
4. Spray-applied, film forming top surface retarder, calibrated for specific sized aggregates and finish requirements without plastic covering. Color coded to allow for ease of application and verification of grade being used as well as even and complete coverage.

It is the responsibility of the applicant to ensure the recycling requirements are met by working closely with the approved waste hauler(s). Applicant must keep records from all waste hauler(s), weight tickets from the C&D recycling centers/landfills for all aspects of the project including construction, demolition and subcontractor activities. These records will be necessary to prove your recycling tonnages and will be required to have your retention released at the end of the project. Failure to comply with this requirement may result in a forfeiture of retention funds for non-compliance.
City of Santa Clarita Franchised Haulers
All temporary bin and roll-off box services in the City of Santa Clarita are franchised by the following companies. General contractors who subcontract services shall ensure all subcontractors are either using a City franchised hauler or are eligible to self-haul. Records of all contractor and subcontractor activities are required to be maintained for project closeout.
If you are not self-hauling, you must use one of the haulers listed below:
Self-Haul
Contractors and sub contactors may self-haul their own construction and demolition materials only if they possess a valid California contractor's license for their scope of work. For example, in order for a framing contractor to self-haul, the framing contractor shall be licensed with the California State Licensing Board (CSLB) to conduct framing services and can only haul materials attributed to their specific trade and may not offer hauling services to other unrelated trades.
Completion of a self-hauler verification form is requested for project closeout.
