Dilution: ready to use.

Application:
1. Determining contact timeGiven the diversity of materials, the most suitable contact time must be determined by running a test on an unlaid tile or a limited and hidden area.Protect the adjacent materials and areas not being treated.PROGRIP 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. Preparing 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 encrustation, or PS87 PRO for organic dirt or film caused by improper maintenance).For easier application, split the surface into areas between 1 and 3 m2, taking care to delimit the area at the joints.3. ApplicationApply PROGRIP to a clean, dry surface using a leathercloth or white pad and leave for the determined contact time, ensuring the surface stays wet throughout.Then clean with a liquid vacuum cleaner 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 neutralising wash using CLEANER PRO (diluted 1:200 or 25 mL in 5 litres of water) and a white pad on the entire treated surface.
