V.O.C. (Volatile Organic Compounds): Limit value of maximum V.O.C. content according to EU (Directive 2004/42/ΕC) for the particular product (category A/c: `Coatings for exterior walls of mineral substrate’, Τype WB): 40gr/lt (2010). The ready to use product contains maximum 17gr/lt V.O.C. • Detached elastomeric materials, that are not visible, can be found using a garden hose. Pour water on the roof surface from about 1 meter high. Notice the change of the sound the water makes when it hits the detached parts of the waterproofing and mark them. Cut the detached sections using a razor blade, or other mechanical means and scrape the defective material off. Application: For applications on cementitious surfaces, and by using a roller, first apply the micromolar stabilizer AQUAFIX, or the SOLVENT BASED PRIMER, diluted 30% with THINNER 101 of DUROSTICK. Alternatively, if the roof does not have any deteriorated sections, dilute DS-220 with water, at a ratio of 1:1 and use it as primer. Once the priming product dries, locate any possible hairline cracks (0.1- 0.4mm). Individually coat each crack with one or two layers using the undiluted product, to seal them completely. If the width of the cracks is between 0.5-1mm, it is recommended to seal them using the ACRYLIC CAULK or the elastomeric sealant, DS POLYMER of DUROSTICK, using a putty knife. Continue by applying two coats of DS-220 over the cracks to complete their sealing treatment. Complete the surface waterproofing by applying two coats over the entire area using undiluted DS-220 of DUROSTICK. Apply the second coat crosswise to cover any minor substrate imperfections, once the first one is completely dry and walkable. USEFUL TIPS - NOTES • Mix well before use. • Avoid applying the waterproofer if there is a possibility of rain for the next 24 hours. www.durostick.com
