Dilution: ready to use.

Application:
1. Determine the contact timeGiven the diversity of materials, the most suitable contact time must be determined by running a test on an uninstalled tile or on a small, inconspicuous area.Protect the adjacent materials and areas not being treated.PROGR1P takes effect after just one minute. After running the 1-minute test, if more time is required the test may be repeated with progressively longer contact times.2. Prepare the surfacePrepare the surface for treatment by washing according to the type of dirt on the surface (e.g. DETERDEK PRO for limescale or cement grout haze, or PS87 PRO for organic dirt or film caused by improper maintenance).For easier application, split the surface into areas between 10 and 32 sq. ft. delimiting the area at the joints.3. ApplicationApply PROGR1P to a clean, dry surface using a lambswool applicator or white pad and leave for the determined contact time, ensuring the surface stays wet throughout.Then clean with a wet vac or remove the residue with a cloth or mop.Rinse thoroughly with water and move to the next area.It is important to apply the product to all areas being treated for the same length of time and with the same method in order to achieve even results.After treatment, we recommend a neutralizing wash using CLEANER PRO 1:200 (1 1/2 tablespoons of product per gallon of water) and a white pad on the entire treated surface.
