Stained concrete floors are a low-maintenance alternative to other types of flooring, such as carpets and hardwood floors. A concrete floor is more durable than other types of flooring since it doesn’t easily scratch and can handle heavy equipment. Maintenance needed to keep the floor polished is minimal, and the designs are versatile and can accommodate different kinds of stains, depending on the taste of the home or business owner. In New Orleans, acid stained concrete can be a good functional and decorative option for those who want a sustainable yet stylish floor.
Checking Concrete Compatibility
Before acid staining, we make sure the concrete floor is in good condition for the type of stain to be applied. Floors that have been waterproofed will be resistant to the stain and reaction cannot occur, so checking the floor before attempting to do acid staining is crucial. The water test should be sufficient to know if a surface has been treated with waterproofing agents. Simply pour some water on the surface, and if the liquid is not absorbed and beads form, then the concrete has most likely been treated with waterproofing agents.
Preparing the Surface
Once we’ve checked that the floor can be stained with an acid base, then proper preparation begins. When using acid stains on concrete, such as Sundek’s SunStain SunAcid Reactive Stain, power-washing the area to be stained is the primary step to remove dirt and all possible contaminants that the concrete has on its surface. The area must be allowed to dry out completely afterward until there is no sign of water or moisture left.
Staining the Concrete
Application of Sundek’s SunAcid comes next, and the reaction is given at least two hours to settle. After the concrete is allowed to react with the acid, the stain has to be neutralized. A neutralizing solution, usually part water and part ammonia, is applied to the surface, washing away the stain residue. Fully neutralizing an area may take more than one scrubbing to take away the residue, especially if a darker stain color was applied and if the stain was left on for a longer period.
Once the stain has been neutralized and the floor is ready for finishing, a proper sealer should be applied. To enhance protection of the newly stained floor, Sundek’s Crystal Clear solvent base sealer can be used. It is also used to improve the appearance of the acid stained floor and make sure that the stain stays on.
