General Finishes®, ENDURO® White Undercoater, 5 Gallon
General Finishes Professional Enduro White Undercoat is similar to General Finishes Sanding Sealer with the addition of white colorant to provide a primer undercoat for white/off-white wood finishes. Want to tint to a darker color? Use Enduro Deep Base Primer instead. Both are EXTERIOR rated and tintable, and the high solids, heavy-bodied formula facilitates a fast film build and easy sanding. Use as a basecoat for pigmented finishes. It dries tack-free in 30+ minutes. Particularly effective on MDF. Enduro White Undercoat can be brushed, rolled or sprayed and applied over raw wood, MDF, existing finishes. Perfect for using as an undercoat for lighter-colored pigmented topcoats and paints. It acts as a physical barrier rather than a chemical barrier. For priming light or pastel colors.
- To accelerate dry time in humid conditions, add General Finishes Accelerator and work in a space with good ventilation and air movement.
- Spills may be able to be removed from fabric and carpet if cleaned immediately with soap and water.
- General Finishes products do not last forever, even when unopened. They are best used within 1 year. The life of the product may be extended with proper can closure and storage conditions.
- Water-based products can last 3-5 years if the can is unopened, in good condition and stored in correct temperatures.
- Product that is 3 years old will not look like product that is 6 months to 1 year old. You will see more stratification or separation as the product ages. Settling is natural. Always stir thoroughly before using.
- If your product has a foul smell, it is contaminated and no longer in useable condition.
- Gravity can cause some solids to settle on the bottom of the can and slight separation on the top. This is normal. If working with older product stir with a paint mixing attachment on a drill. If the solids dissolve and clumps smooth out after mixing from the bottom, the product is in good condition for use. Inability to reincorporate large, chunky lumps after stirring for several minutes is an indication that the product has frozen and can no longer be used.

Preparation for Raw Wood:
- Sand with 120-grit sandpaper followed by 150- or 220-grit sandpaper.
- Remove dust with a water-dampened rag or oil-free tack cloth.
- Let dry completely before applying GF product.
- Do not over-sand with fine-grit sandpapers; this will close and seal the wood grain, preventing ideal color absorption.
- Do NOT use steel wool with water-based finishes; the particles will get trapped in the finish and rust.
