Transformation Stain Siding and Trim was developed as an easy to maintain stain for exterior trim, siding and fences. It is a water and oil emulsion that won’t crack or won’t peel, even under the most extreme conditions. Maintenance is simple – just give it a light power wash and re-coat. Great for decks, wood siding, and fences. It can also be applied on interior surfaces under Symphony Interior Clear Coat.
