ELPRT9000 is a specially designed 1K primer for refinishing and new construction. PRT9000 offers industry leading stain, dye and tannin blocking with great adhesion in an easy to use, one-component water-based primer. ELPRT9000 has excellent adhesion to a variety of existing coatings (solvent or water based) as well as veneers, solid wood, MDF, concrete and stone. Grease and oils will bleed and must be removed prior to application.

NOTE: Do not use 100 series topcoat directly over PRT9000 as it will not adhere. If you require a dark colour we recommend applying a coat of PR180 (tinted) over the PRT9000 to achieve adhesion then apply the tinted 100 series topcoat.


This product is designed for interior wood finishing applications such as cabinetry, tables, furniture and millwork.


IMPORTANT!! LIQUID PRT9000 DOES NOT MIX WITH OTHER MATERIALS!!! Make sure you flush your system thoroughly with water before and after using ELPRT9000. If you load any other product into your system after PRT9000 without a water rinse you will cause resin to kick out leaving grit in your finish and cause signficant gelling or clogging. Reduction is generally not required. Product should be at room temperature and mixed thoroughly prior to application to ensure consistency.

Raw wood/veneer/MDF: Substrate should be sanded with 150 – 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 appearances. If using powered sanders it is beneficial to reduce the speed to prevent heat which will reduce clogging. Two coats can be applied same day back-to-back without sanding between and still acheive good adhesion, a quick scuff is required if more than 8 hours elapsed between coats. All of our primers must be sanded same day as topcoat application as they cure quickly, if the primer is sanded and left overnight it will require a quick scuff with maroon scotchbrite or a super fine sponge for adhesion before applying topcoat.

Refinishing: Thoroughly clean the existing finish to remove old oil, grease, surface stains and any chipped or flaking paint. Sand the substrate with 180 – 320 grit sandpaper or fine sponges depending on the condition of the surface to be refinished. 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.


ELPRT9000 loves heat (conventional or IR) and will be recoatable much faster if you are able to dry it at elevated temperatures.
Please see our notes regarding Dry Times below:

Air dry:

(20°C/68°F) 4-5 wet mils*

Dry to Touch: 30 Minutes
Dry to Sand: 1-2 Hours
Dry to Stack: Overnight

if you apply a second coat or a heavy first coat these times will double.
Dry to Topcoat 2-8 hours (See Below)
The unique stain blocking chemistry of this primer makes it sensitive to early recoat times when air drying without heat curing. Most acrylic, urethane/acrylic or 2K- isocyanate based coatings can be applied within 2-4 hours of primer application. One component polyurethanes are not reccomended for use over T9000 (PR170/ELNYW200) will require CAT100LV hardener or CAT150 crosslinker in order to be applied over T9000. Failure to follow these guidlines can result in topcoats aligator cracking.

Air dry times before applying

1K Topcoat

Envirolak’s 400 or 800 Series can be applied as a 1K over T9000 with 2 hours of air drying at 20C/68F temp or higher with gentle air movement.

Flush all equipment with water until it runs clear. DO NOT MIX LIQUID PRT9000 WITH OUR ELRX110 CLEANER, it will turn into a gelatinous mass that will be very hard to clean up. Clean up wet product with water (no soap) or a blend of alcohol/water. Dried material can be cleaned with ELRX110.


Use stainless steel (304/316) equipment for all water based products.
Keep containers closed when not in use and keep from freezing.
