- Treatment you’re considering: TW2200, TW2200 EX, TW3300 or TW4400.
- Lumber species, dimensions and approximate quantity.
- Job location, intended use and expected exposure.
- Builder, designer or building-official document requirements.

Clear roles. Complete information.
REZWOOD is treated by Texas Wood Tech using TechWood protective wood-treatment technology supplied by Chemical Technologies Holding Corporation (ChemTech), the company behind TechWood. Applicable TechWood limited warranties are provided by ChemTech—not by DrJ—and are subject to the complete written terms.
Technical evaluation, certification and warranty coverage are separate. Original documents retain their issuer, identification and conditions. We’ll help confirm which documents apply; building officials and project professionals still receive any required reports and installation information.
