ELPRT9000 is designed to be used as a 1K product in order to achieve a smooth white basecoat for new construction or refinish applications. PRT9000 offers industry leading stain, dye and tannin blocking 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 or MDF.

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


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 causing signficant clogging. Reduction is generally not required. Product should be at room temperature and mixed thoroughly prior to finishing to ensure consistency.

Raw wood/veneer/MDF: Substrate 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 appearances. 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: 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:


4-5 wet mils*

Dry to Touch
Dry to Sand
Dry to Stack

30 Minutes
1-2 Hours

*if you apply a second coat or a heavy first coat these times will double.
Dry to Topcoat 4-48 hours (See Below)
The unique stain blocking chemistry of this primer 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 PRT9000 was applied. Air movement or heat applied to any subsequent coat over top of PRT9000 will reduce recoat times and the risk of that coat from cracking.

Adding ELCAT100 to the subsequent coat over top of PRT9000 will also help prevent cracking in that coat. See drying notes on using hardener/crosslinker below.

Air Drying with a 2K Topcoat:


If you use ELCAT100 Hardener or ELCAT150 Crosslinker in your topcoat over ELPRT9000 you can recoat in a much shorter window. The following reocat times are recommended when using 2-component topcoats.

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.
These products are designed for industrial use only. Please refer to the Safety Data Sheet prior to use.


12 months in unopened containers


Store in a tightly closed container at room temperature (18-25°C/64-75°F) and protect from direct sunlight and foreign material. Do not store at temperatures below 5°C/41°F.
