Prepdeck stripper/cleaner is a professional, high-grade product specially designed for the removing of old solid and semi-transparent stains, unsightly grade stamps and other finishes from wood.
It is essentially a three-in-one product. Its main purpose when undiluted, is as an effective way to prepare a wooden surface for further treatment. Prepdeck strips away existing finishes along with stains, marks, and grade stamps.
When diluted, Prepdeck can also reduce mill glaze on new wood and prepare the surface to accept a penetrative finish.
The product can also be diluted for use as a powerful wood cleaner with the ability to get rid of even difficult marks and stains.

To strip old finishes and grade stamps
To reduce mill glaze
Add 1 part Prepdeck to 4 parts water – except for Ipe; then add 1 part Prepdeck to 1 part water.
Dilute 1 part Prepdeck to 5 parts water up to a maximum of 1 part Prepdeck to 20 parts water, depending on condition of the surface.

Stripping and Cleaning
Work in areas that can be completed in 15-30 minutes.
Apply Prepdeck to the area to be stripped or cleaned and allow to work.
After an appropriate time, test a small area with nylon scrubbing brush to see if finish or dirt is lifting.
If lifting, scrub area with a stiff nylon brush, deck brush or use a Power Washer at 1000-1500 psi (70-103 bars) depending on type of wood.
Always work in direction of grain.
Rinse with copious amounts of freshwater, using the highest pressure from the water source available or use a Power Washer at 500-1000 psi (35-70 bars) working in direction of grain. (Rinse adjacent areas at same time).
NB: The use of hot water makes the job easier.
