Floor Scored & Several Days Ago

The floors of our home are going to be colored, or stained concrete, we had a top coat of concrete poured over the rough, what I call sub-floor. Which is the steel reinforced concrete slab through which the plumber and I coursed several conduit runs, and the plumber his water supply lines, hot and cold; as well as waste piping.
The top coat of concrete, poured on an average 3/4" to 1" thickness, is white cement. That is, white Portland Cement, instead of the normal shade of gray; the product we used was actually a product of Denmark. Interesting, considering the Danes owned and ran the plantations on these United States Virgin Islands, until the good ole USA bought them prior to WWI, to protect the Panama Canal, I think it was in November of 1917.

In this series I show you the stages of preparation and application for scribing and staining concrete floors. This is my second attempt at this craft, O.K. third try, our Harwich, (MA) barn was project one, the master bathroom in 71 Vista Concordia; and, now, the West Wing. The blue room, above, is in the process of protection from water based concrete stain application. We covered the lower 12" of the walls for this protection, sealed top and bottom to prevent leakage behind the protective membrane. We will leave this in-place until the floor is stained, scored, rinsed and the mildly acidic stain is neutralized; and, finally, sealed with a lacquer based concrete sealer.

We are using products from a company in Florida, under the name of Decosup, or decorative concrete supplies. Decosup's floor stains are a non-acidic solution which don't require HAZMAT (Hazardous Material) shipping. After all, shipping to this Island, 2,300 miles from Miami, FL, is expensive enough as it is for normal shipping rates.This shot of the south bedroom, sorry, the blue room, viewed down the Greenie Beanie (the name of the paint color) hallway, shows the application of the 1st stain coat, note the plastic film wall protection, taped to the wall top and bottom.

That black, cylindrical. & hosed aparatus in the center of the doorway is the stain applicator. I simply pour in the stain, pump up the pressure and pull the pistol grip handle to spray the liquid on the floor.

The vacuum cleaner I use for dust collection, and the floor jig for cutting straight lines is on the floor. The jig consists of two pieces of 1/4" masonite held parallel at the right dimension to allow for the concrete saw's footprint. This insures a straight and unwavering cut in the surface. The white cement, used to pour this layer, is extremely hard at this point, being fully cured now for several weeks. The handle of the saw pokes out of the closet at left of photo.
