I am the Southern California distributor and master installer for SealwiZe products. In response to your question regarding our sealer pls note the following...1. The ZR-44 wood sealer is guaranteed for up to 30 years. Not a lifetime. 2. This is an inorganic sealer and unlike organic sealers it does not break down over time. 3. We have been restoring wood decks with ZR-44 for years and have not had a single warranty claim. 4. The wide difference in price is not due to the cost of the sealer. It is due to the cost of labor to properly prepare a deck to receive the sealer. 5. It is important that the deck is thoroughly stripped with a 100% environmentally safe stripper, brightened and then neutralized to balance the PH value. It must then be thoroughly sanded and profiled so the pores are open and will absorb the sealer. 6. Finally the deck must have no more than 20% moisture content before the sealer can be applied. ZR-44 will seal a deck and seal it well provided the above steps are followed. 7. The only thing that is required is an occasional cleaning. 8. If you chose a colored version of Zr44sealer the color will need to be refreshed every 5-7 years. However the sealer itself will continue to work well beyond that.
