"\nEnvirolak T9000 primer is a 1K bonding and stain blocking primer for new construction or refinish applications. \nEnvirocryl T9000 offers industry leading stain, dye and tannin blocking in an easy to use, one-component water based acrylic primer. T9000 has excellent adhesion to a variety of existing coatings (solvent or water based) as well as veneers, solid wood or MDF.\n\nT9000 blocks tannin, stains and dye migration in one coat in most cases. For stubborn bleeding a second coat may be required. \nIf you are using a dark colored topcoat, it is necessary to apply 1 coat of Envirolak 170 or 180 primer after applying T9000. T9000 cannot be tinted and is only available in white.\n\nRaw wood/veneer/MDF: The surface should be sanded with 180 - 320 grit sandpaper prior to applying primer. Very lightly sand primer with 320 grit or fine sponges prior to application of next layer for best appearance. You may apply another coat of PRT9000 on itself without sanding in between. If using powered sanders it is beneficial to reduce the speed to prevent heat which will reduce clogging.\nRefinishing: The existing finish needs to be thoroughly cleaned with a degreaser to remove oil, grease, surface stains and any chipped or flaking paint. Sand the substrate with 180 - 320 grit sandpaper or fine sanding sponges. Failure to properly prepare a previously finished surface prior to finishing with ELPRT9000 may result in film failures such as fisheyes or loss of adhesion.\nTypical system for light color refinishing with a 1K topcoat:\n\nPrep surface with degreaser and clean (simple green, krud-kutter, insl-x heavy duty degreaser). Rinse with dish soap and water. Let the surface dry.\nSand with 220-320 sand paper or fine sanding sponges.\nApply a coat of T9000 bonding/stain blocking primer at 4 mils.\nWait 1-2 hours, 2 hours to be safe, sand with 320 grit or very fine/super fine sponges.\nMix in 3% by weight/volume of isocyanate free crosslinker (optional) and apply a coat of Envirothane 800 series 1K topcoat. \nApply additional topcoat after 1-2 hours, if necessary. \n\nDrying schedule:\nTo Touch: 30 minutes \nTo sand: 1-2 hours\nTo topcoat: 4-24 hours (1-2 hours with Envirothane 800 series 1K)\n\nThe unique stain blocking chemistry of T9000 makes it sensitive to early recoat times when using 1K polyurethane products. Most acrylic, urethane/acrylic or 2K isocyanate based coatings can be applied within 2-4 hours of primer application. One component polyurethanes (PR170/ELNYW200) may require overnight drying or longer if more than one coat (&gt;5 wet mils) of T9000 was applied.\nAir movement or heat applied to any subsequent coat over top of PRT9000 will reduce recoat times and the risk of that coat from cracking."
