Armor Acid Stains react chemically with the mineral content and excess lime of the concrete surface for a deep penetrating, UV stable and permanent stain.
Per gallon coverage is 150-300FT2.
Coverage rates vary depending upon surface porosity and texture, and application method. Excessive build up should be avoided. Please note that product can be diluted up to 1:1 with water yielding double the coverage per actual gallon of stain purchased.
Always test the stain in an inconspicuous place. Allow to dry for 4-6 hours. Rinse the test area and observe the color while wet.
Any of the Foundation Armor solvent-based top coats can be applied to the surface once stained. For a durable, long-lasting finish consider one of the many Foundation Armor concrete coatings including the Armor UTN60, Armor Epoxy, Armor AR350, Armor AR500, or the Armor AX25.
