Wood Hardener for Rotted Wood Repair

PC PRODUCTS 128442 is a liquid wood hardener designed to penetrate and solidify damaged or rotted wood. The milky white formula comes in a 128 oz bottle suitable for indoor and outdoor restoration projects. It prepares compromised timber for patching, painting or staining once cured.

Ambient Cure with One Hour Working Time

The water based polymer cures at ambient temperature and provides a working time of 1 hr before setting. Full cure is reached in 1 wk, after which the treated surface becomes paintable and stainable. Coverage reaches approximately 200 sq ft depending on wood porosity and damage depth.

One Gallon Capacity for Medium Scale Jobs

The 1 gal container handles typical repair areas on furniture, trim or structural elements without frequent refills. Low VOC formulation meets SCAQMD standards for regulated environments. Very large or severely deteriorated projects may require multiple bottles to achieve full penetration and strength.
