Junckers' primer range covers two different jobs — WB Primer for whitewash-style colour effects, and SB Primer as a general-purpose bonding primer suited to a wider range of wood species.
WB Primer: Whitewash Effects in Three Shades
Junckers WB Primer (formerly Prelak) is a water-based, fast-drying primer that adds a whitewash shade to the floor as it primes it, available in Clear, White and Nordic. It's designed to be overcoated with Junckers MT500 or HT700 floor lacquer, or other compatible water-based finishes, and the choice between the three shades comes down to how strong a whitewash effect you're after.
SB Primer: For Sanded and Exotic Wood
Junckers SB Primer (formerly BasePrime) is a quick-drying primer that works with both Junckers' solvent-based and water-based lacquers, and is suited to most sanded and untreated parquet floors — including most exotic wood species where WB Primer's whitewash effect isn't wanted. Rather than whitening the wood, SB Primer gives light-coloured woods a subtle light-gold appearance instead.
Common Questions About Junckers Primers
What's the difference between WB Primer and SB Primer?
WB Primer builds a whitewash effect and is used with water-based lacquers. SB Primer works with both solvent- and water-based lacquers, suits a wider range of wood species including exotic timbers, and gives a light-gold tone rather than a whitewash.
Which WB Primer shade should I choose?
This depends on how strong a whitewash effect you want — Clear, White and Nordic give progressively different levels of whiteness, so it's worth checking a sample against your specific floor before committing to a full 5L.
Can SB Primer be used with any Junckers lacquer?
It's designed to work with both solvent-based and water-based Junckers lacquers, making it a flexible choice where WB Primer's water-based-only pairing doesn't fit the planned finish.
