Protecting the Concrete Slab
Do not write on slab with anything other than pencil. Framers are to use blue chalk only. The following are examples of what may penetrate and permanently stain the slab - red chalk, wax pencils, adhesives (tape), PVC primer / glue, primers, paint, caulk, flux, oils, gas, grease, liquid nail, silicone, food, coke, coffee, (other beverages included), metals left on slab can leave rust and oil marks (nails, angle iron, etc.). When ladders are being used on slab, the feet of the ladder should be wrapped or capped to keep from scarring and marking the slab. Do not set buckets or cans of anything directly on slab. Liquids and gels are our enemy. Slab should be cleaned daily. Plywood, stacked lumber, sawdust, insulation board, pressboard, polyethylene (plastic) can draw moisture from slab and cause patterned water stains to slab. Wall plates for doorways and cased openings need to be cut out early in framing process. Do not anchor to slab as the divots can be patched but will not match perfectly.
*** Areas that will be scored, stained, or polished should be kept clean at all times ***
Floor must be kept covered during the priming / painting / lacquer processes. Protect floor with rosin paper, green paper overlapped and taped (No tape directly on floors). After trim package is complete and baseboards are to be painted, it is recommended that blue painter’s tape and rosin paper be applied to floor edges to protect finish. Masking must be removed immediately upon completion of paint.
Contractor, Owner and all Sub Contractor Awareness - Finished Concrete Floors
ALL who are involved with the building project should read and understand the following information regarding this process. It must be verbalized often that the concrete slab will ultimately be the finished floor.
Concrete Sub Contractor
Under slab Vapor Barrier / Retarder (10 or 15 mil Polyethylene) to be placed before concrete slab being poured. Vapor barriers can be purchased at most concrete supply stores. All beams should be wrapped and all tears must be repaired prior to placing concrete slab. Preferably use minimum five-sack mix (3000 psi). Do not use surface curing compounds, retarders or chloride accelerators. Do not use fly-ash below 80F. Use no more than 15% fly-ash above 80F. Do not use fiberglass mesh or fibers in concrete mix. Do not walk on slab before surface is dry to avoid footprints. Keep trash from blades to prevent swirl marks. It is important to finish with hand tools around plumbing, risers, floor outlets, or any other areas not accessible by the machine. Blend the areas at the edge of the slab. If the finish is smoother in the center and rougher at the edges there will be a noticeable difference of color tones in these areas.
Interior Applications
The slab should be power trowelled by machine to a smooth finish. The concrete finishers can burn swirls to create a marble-like finish. Try to achieve a consistent / semi-consistent finish over complete area to be stained. Do not have one area super slick and an adjoining area semi-rough. Consistency is the key to a beautiful end product.
Exterior Applications
To achieve a slip resistant, limestone-like finish, the concrete finishers can apply a heavy rock salt finish. Also, a light broom finish can be applied to achieve slip resistance.
The floors should be clean and the room empty, with absolutely nothing on the floors prior to the arrival of our crew. Our fees do not include removing paper, moving furniture, equipment, fixtures, building materials, etc… Additional moving and cleaning will be charged as additional labor.
Application Schedule
Scoring should be done as soon as framing is finished. We will come back to stain and pre-finish immediately after dry in before mechanical, insulation, drywall, or masonry. We will need water on-site. Area should be covered after a minimum of 48 hours of receiving pre-finish. We suggest covering to be with single faced cardboard(smooth side up) overlapped and taped at the seams. DO NOT TAPE TO THE FLOOR. You can find the rolls cardboard at ECONO-BOX, STAIN IT, or PAPER PLUS( all in Austin, Tx.) We will cover for an additional charge. We will return after final cleaning to apply the final finish. We are not a cleaning crew therefore all paint, mud, spills, etc… must be cleaned or scraped before we arrive to avoid incurring additional costs.
