Envirolak Envirothane High Solids Primer, ELPR 170 & 170TB

Introducing ELPR170 and its tannin-blocking variant, ELPR170-TB—two premium wood primers by Envirolak, designed for interior wood finishing. Whether you’re working on cabinetry, furniture, or millwork, these primers offer fast drying, superior filling properties, and versatility for professional-grade results.

Key Features

✔️ High-Solids Formula: Both ELPR170 and ELPR170-TB are high-solids urethane primers, providing excellent filling capabilities. This means fewer coats are needed, saving you time and material.

✔️ Smooth Surface Preparation: Perfect for medium-density fiberboard (MDF), solid wood, and veneers. These primers help prepare surfaces by preventing swelling and improving adhesion. ELPR170-TB includes a special tannin-blocking formula to stop stains from bleeding through, making it ideal for problematic woods like oak or cherry.

✔️ 1K or 2K Systems: They’re flexible in their application—whether you want a one-component (1K) or two-component (2K) system. Add CAT100-LV Hardener for even better performance and adhesion to different substrates.

✔️ Fast Drying & Easy Sanding: These primers dry quickly and are ready for sanding in just a few hours, helping speed up your project timeline.

Differences Between ELPR170 & ELPR170-TB

• ELPR170: A universal urethane primer without tannin-blocking capabilities. Ideal for general interior wood applications.
• ELPR170-TB: The same high-quality primer but with a tannin-blocking additive, making it better suited for woods that release tannins (which can cause discoloration).

Application

Both primers can be applied using a variety of methods—spray, brush, or roller—and they can be top-coated with most waterborne or solvent-borne topcoats.

Ideal Uses:

• Cabinets
• Furniture
• Millwork
• Veneers
• Solid Woods prone to tannin release (ELPR170-TB)
