You can never sweep your stained concrete floor often enough, as dirt and foreign particles act as abrasives. By removing these abrasives, we decrease the threat of deterioration to our floor’s shine while protecting the low maintenance characteristics of a concrete floor.
Do not use any liquid curing compound to retard water evaporation from the slab. Anything oil or waxy completely blocks penetration of acid stain. Of course, use no sealers.
Use normal, moderate troweling. Do not allow burnishing with metal trowels and avoid the use of a power troweling machine. If slab is too smooth, the pores are closed and staining becomes spotty.
You will need to protect the slab from tar and paint overspray or plaster residue. Let slab cure for at least two weeks, and then lay down plastic. Wrinkle the plastic in a random manner, so there are not long, straight folds running across the floors. Every light-dark difference in the concrete will show through our translucent stains. Do not worry about rain spots; we have found that these give a natural looking mottled effect.
When covering the slab, do not use sticky tape to hold the covering down. This leaves dark, blocky marks in me concrete, which are permanent. You might place 2x4s or chipboard down to weight the plastic.
Framer’s markings can be impossible to remove if they are done with red chalk or crayon. The best thing for us is blue or white chalk, with hairspray used as a fixative. Even pencil and felt-tip pen can be indelible if left on for months. Wash off or sand these as soon as possible, if they are applied to the slab.
The acid stain can be wicked up and turn wood black, so it is good to have wood doorframes painted or sealed before floor staining begins. (Have the painter use brown paper below to catch drippy sealer. It looks invisible until floor staining begins). If kitchen islands and cabinets must be installed before floor is stained, it is a good idea not to install the kickboards along me bottom edge until after the floors are done. If hardwood floor areas are going to abut the acid-stained floors, the staining should come before laying the wood floors.
