Envirolak T9000 Primer Stain Blocker and Bonding 1K ELPRT9000
ID: #593082
Description
Envirolak T9000 primer is a 1K bonding and stain blocking primer for new construction or refinish applications. Envirocryl 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. T9000 blocks tannin, stains and dye migration in one coat in most cases. For stubborn bleeding a second coat may be required. T9000 can be tinted gray up to 5% by weight with T9000 Black Tinter . The new version of T9000 can be used outside, sands better, and is compatible with 100 series. The new version of T9000 cannot be mixed with the old version. Raw 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. Refinishing: 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. Typical system for light color refinishing with a 1K topcoat: Prep surface with degreaser and clean (simple green, krud-kutter, insl-x heavy duty degreaser). Rinse with dish soap and water. Let the surface dry. Sand with 220-320 sand paper or fine sanding sponges. Apply a coat of T9000 bonding/stain blocking primer at 4 mils. Wait 1-2 hours, 2 hours to be safe, sand with 320 grit or very fine/super fine sponges. Mix in 3% by weight/volume of isocyanate free crosslinker (optional) and apply a coat of 800, 400, or 510 topcats Apply additional topcoat after 1-2 hours, if necessary. Drying schedule: To Touch: 30 minutes To sand: 1-2 hours To topcoat: 4-24 hours (1-2 hours with 800, 400 or 510 1K) The 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 (>5 wet mils) of T9000 was applied. Air movement or heat applied to any subsequent coat over top of T9000 will reduce recoat times and the risk of that coat from cracking.

If you're spraying clear coats, or WB coatings like Centurion , Novalk , Envirolak , or Renner, the most popular sizes are: For topcoats: 306 , 406, (Centurion 400 & thinner viscosity clears) 308, 408 (for most 1K/2K topcoats & thixo products). For primers: 308, 408, 310, or 410. When spraying with 06 tips it is recommended that you strain your material with a fine mesh filter before spraying. 06 spray tips are not recommended with the Graco Quickshot, box store Graco airless sprayers, or for use with trim paints like Emerald Urethane. Highly thixotropic products like Novalk 932, Renner 765 or ICRO 5000 will also struggle with an 06 tip. We recommend a 308 for thixo products. Tip sizing: the first number is the fan size in inches. It is multiplied by 2 and is approximate. For example, a 308 has roughly a 6 inch fan, and a 0.008 inch orifice size. All 06, and 08 tips are not recommended for use with a Graco Quickshot.
