Builders Instructions
The final appearance of stained floor project will be determined primarily by the quality of the concrete pour, the finish of the slab surface and the ongoing protection of that slab during construction. The builder should be responsible for relaying all of the following information to the concrete contractor, the concrete finisher and all sub-contractors involved. Communication of these issues to all construction personnel is vital to the success of any staining project.
General slab components for interior and/or exterior flatwork:
Five (5) sack mix
Usually a smooth but porous machine trowel finish
Not too slick or too hard
Swirls from troweling will add uniqueness to the floor
Standard mixture with no additives, fillers or curing agents
Texturing (broom drags) may be desired for exterior slip resistance
Allow slab to dry for 24 hours before any foot traffic
No to little fly ash
No moisture restrictors
If a wet cure is called upon, place burl lap over concrete. Plastic will create folds/lines and leave an unfavorable impression.
These issues will have an adverse impact upon the quality of the finished stained floor:
DO NOT use additives, fillers, or curing agents, if possible
DO NOT apply a CURE and SEAL as this will need to be mechanical ground off altering the final look
DO NOT cover slab during early construction as it needs to cure for 4 to 6 weeks
DO NOT nail support studs into the concrete
DO NOT spill or drip plumber’s glue of flux onto the slab
DO NOT use paint sprays to locate floor plan locations or outlets
DO NOT tape or adhere anything to the slab
DO NOT use muratic acid, acid washes or acid etch at any time
DO NOT use alkali cleaners on the slab
DO NOT leave or place wood on the slab as it will leave an impression
DO NOT leave nails or metal on the slab as they will create rust marks
DO NOT use silicone based chalk or crayon as removal is near impossible without sanding
DO NOT drip or spill plastering, texturing materials or paints on slab. We recommend to use heavy duty temporary floor protection after the slab has cured.
Some additional issues:
Protect the slab well during the installation of blown insulation (foam and fiber)
Pest control products that are petroleum based should not come in contact with the floor
Always allow complete curing of any patching or pour back before attempting to stain
