Concrete Polishing Maintenance Program Schedule

School Maintenance Program

Products: Floors have been densified and polished with Consolideck® Ls and with the Protective Treatment, Consolideck® LsGuard.

Concrete Floors: Polished concrete floors contain reactive sites even after the initial densifying and polishing. A chemical reaction occurs when the densifier comes in contact with calcium hydroxide produced during the concrete hydration process migrating to the surface of the slab. These sites remain ready for exposure even after densifying and polishing. When the surface is scratched during normal foot traffic from rocks embedded in shoes new reactive sites are exposed. We recommend a cleaner be used that includes silicates to react with those sites. Consolideck® LsKlean™ was developed with a lithium silicate along with neutral cleaners. LKlean Super Concentrate was developed taking the water out, but is the same product.

Evaluating the Floor Area and Create Cleaning Zones: Not all floors experience the same exposure. Traffic across in different areas of the building will lead to different exposure rates. Some areas will require a higher degree of cleaning and certain times of the year because of climate conditions can affect the cleaning cycle. We recommend that meet owner's expectations, not only on maintenance cost, but specifically surface specular gloss levels the floor be broken into cleaning zones. Individual areas are impacted differently. Obviously the entry/exit and multi-purpose areas need attention daily, but other areas will not require the same degree of attention. Finding a method to analysis the facility will go a long way in managing costs.

Daily Cleaning: This needs to be a step by step program explaining dusting, sweeping, how to treat the floor etc. and needs to be tied to the Cleaning Zones.

Supervisory Inspections: All facilities face varying activity and therefore, require adjustments to any schedule. We recommend supervisory personnel walk area to confirm activity and abrasion on the floor are normal. If additional activity or abrasion is noted additional corrective actions should be taken. Areas such as; cafeteria, entries, etc. where issues may be developed should be paid close attention.

Quarterly - Surface Evaluation and Burnishing

• 4x / Day – Survey hot areas determined by where spills may occur
• Evaluate the gloss level by taking readings and comparing to gloss level at finish of project
• If Gloss level drops 10% below final gloss level, burnish surface with high speed propane burnisher using Consolideck® HEAT Burnishing Pad
• Evaluate water resistance by pouring drops of water from one (1) foot off the floor and confirming water bead
• Allow water to sit for a minimum of five (5) minutes. Then blot up excess. Concrete below should show dark wet spot. Check back after thirty (30) to sixty (60) minutes and confirm water spot has NOT blushed white and has disappeared.

Spill Mitigation

Note: Prepare Spill Kits to have available in area where spills, standing water etc. are expected. We recommend a Log Book be maintained to insure communication to other maintenance staff. His would involve notification if additional work required to protect the floor.

Equipment

Weekly or Twice Week Cleaning

Note: The need to clean the floor is required to prevent abrasive material, i.e., dust, dirt, rocks, etc. from abrading the surface. The use of the cleaner without wax is required to prevent buildup and the need for removal.

Post Equipment Maintenance (when cleaning is complete)

• Remove auto-scrub brushes or pads and hose down pads to remove any dirt or grit. DO NOT LEAVE PADS WITHOUT CLEANING
• Clean mops, buckets and their Equipment to remove dirt or grit

Burnishing - Weekly or Monthly

Note: The Protective Treatment Consolideck® LsGuard is a breathable acrylic polymer. It protects the floor from abrasion and provides open time to mitigate spills. As stated it is breathable and will allow the concrete below to wet out, but moisture will breathe out and the concrete wet spot will disappear. We recommend using a Horiba Gloss Checker IG-331 or similar devise to monitor the floor abrasion. Areas that begin to lose gloss are a result of excess abrasion. If gloss levels fall below 10% of the standard then burnishing may be required. We would recommend records be kept for the first year to evaluate necessary frequency of this procedure. We would recommend that otherwise it should be done monthly.

Protective Treatment Spiff Coat - Quarterly

Note: The Protective Treatment, Consolideck® LsGuard may be required to be reapplied because of abrasion on the floor. If only a select area requires attention then apply Spiff Coat in that area and burnish entire floor. Gloss level or sheen will blend in on all surfaces. It is not necessary to apply to entire area. The entire area should be coated annually.
