2. Reinforcement. A secondary reinforcement like polypropylene fiber will help minimize cracking.
3. Cure. A wet cure is preferred over a disappearing cure and seal, since a cure and seal will need to be removed.
4. Cutting. Timing is critical for joint cutting. The depth of the cut should be at least one-fourth the slab depth but one-third is better.
5. Slab protection. All trades involved on a job should understand how their spills and traffic can ultimately affect the success of the floor finish. Don’t allow trades to use the slab as a staging or cutting area as this could result in damage to the concrete or differential curing which can leave visible discoloration on the slab.
6. Timing. Pour the concrete as late in the process as possible.
7. Edges. Install non-load bearing walls as late as possible to reduce hand edge work — saves the contractor labor time and results in a better floor.
8. Strength. 4,000 psi concrete and higher is ideal for an exposed aggregate finish.
9. SCMs. Minimize fly ash or slag cement replacement in an exposed aggregate finish.
10. Materials. Use one source for your cement and aggregate throughout a project.
11. Mix design. Get your mix designs approved by the architect and talk through the characteristics of a mix design that contribute to a successful exposed aggregate floor.
12. Color. If adding integral color, use liquid color or make sure the disintegrating bags are removed from the batch (don’t let them disintegrate in the mix). If your floor will be dyed or stained, make sure your trowel blades are clean and use plastic trowel blades if possible.
13. Placing. Plan your pours from the front door to the back door, not side to side. This will put your pour joints front to back instead of side to side, reducing the impact of slight color variation in the different pours.
14. Flatness. FF and FL numbers 40 and above will make for a better polished finish by offering a flat and level floor that produces a better clarity of reflection
15. Decorative cuts. Make your decorative saw cuts before you grind/polish to avoid finish degradation.
16. Finishing. Keep the finishers off the slab during the finishing process to avoid depressing the aggregate. An even aggregate distribution will result is an even aggregate exposure.
Total Polished Solutions runs multiple job sites, oftentimes is different states throughout the U.S. A few years ago the company started using Salesforce.com CRM (customer relationship management) software. Salesforce.com is a cloud-based program that allows project managers access through an Internet connection anywhere in the country. "Every morning, project managers upload job site photos and progress reports for each job. Company leaders can review this information from anywhere," Thomas explains.
