Where application is over an existing sound coating, trials should be conducted to ensure compatibility of the Durafloor PU with the existing coating as well as retention of the bond of the existing coating to the host substrate. For further advice contact your local distributor or Parchem sales office. Application 1st Coat For porous surfaces the first coat must be diluted to penetrate into the substrate and provide better wetting. Dilution can be up to 50/50 with xylene. If there are some doubts about application and appearance, test a small area first. Diluted sealer must be used immediately and not stored or returned to original sealer. Decant the quantity of Durafloor PU required for immediate use only. The original container should be re-sealed immediately against moisture. Apply Durafloor PU by either a brush, roller of airless spray. For spray application, between 5% - 10% xylene can be added. A slip resistant additive may be required, particularly if the area gets wet. Refer to Parchem for advice. Application recoating Re-coating should be within 16 -18 hours dependent on conditions prevailing. If too much time is allowed for cure, adhesion can be difficult to obtain on subsequent coats. If too much time has elapsed then the first coat will have to be sanded to provide extra key before the second or third coats are applied. After sealing it is recommended that the sealed surface be protected from: Foot traffic for a minimum of 48 hours Vehicle traffic for a minimum of 72 hours Cleaning Durafloor PU can be removed with water when wet and with xylene. Once cured Durafloor PU should be removed from tools etc by mechanical means. 245 Durafloor® PU Single pack, high build, clear high gloss, high abrasion resistant polyurethane coating Uses Durafloor PU is a high build coating, formulated for both interior and exterior applications to provide a clear, high gloss, high abrasion resistant finish.
