207-sa Special Clear Hardener, 10.6 Oz

West System 207-SA is a special clear hardener curing agent designed for epoxy coating and fiberglass cloth applications where an exceptionally clear, moisture-resistant, natural wood finish is desired. When blended with West System 105 epoxy resin, this hardener will not blush or turn cloudy in humid conditions, solving a common problem in woodworking and marine projects. It is ideal for builders and DIY enthusiasts who need reliable results on wood and fiberglass surfaces without the frustration of a hazy or cloudy finish.

This blush-free formula allows thin film applications to roll out and tip off smoothly, requiring less sanding in preparation for finish coatings. Professional and first-time builders alike appreciate the 207 hardener because it is reliable, easy to use, and produces consistent results. Three coats or more can be applied in one day without additional surface preparation, and in most cases the final coating can be sanded the following day, allowing projects to progress faster.
