Remove surface dirt by sweeping or hosing.
Shake Dex Prep thoroughly and mix in a plastic container or bucket. For general cleaning, one part timber cleaner to five parts water. For severe staining or
discolouration a stronger or undiluted solution or repeat application may be necessary.
Quantum Dex Prep may not remove old deep seated fungal stains and timber marking dyes.
Wet the surface to be cleaned.
