When comparing General Finishes Outdoor Oil and Exterior 450 outdoor water-based topcoat , there are several key differences to consider:
Outdoor Oil:
Exterior 450 Topcoat is a tintable clear-drying low VOC finish suitable for vertical exterior surfaces, such as fences, patio furniture, garage doors and entrance doors. It is not recommended as a deck finish.
GF's Exterior 450 Stains are low VOC premium quality, exterior pigmented water-based wood stains designed for outdoor projects with vertical surfaces such as garage doors, entrance doors and furniture.
General Finishes NEW Exterior 450 White is a water-based exterior-rated pigmented coating for use on vertical surfaces such as outdoor kitchens, entry doors, garage doors, and windows.
As seen in Green Building and Design Magazine.
Water-based coatings are the future of finishing. You may not be using them today, but you will be in the next five years.
It would depend on whether you plan to use the furniture outside or under the protection of a roof. Theoretically, both water and oil-based products could be used.
For example, you could "antique" wicker with thinned Gel Stain to pop up the color depth on an aging piece of natural wicker. However, Gel Stain is not exterior-rated and is very thick, making it cumbersome to apply and wipe off on a highly textured surface such as wicker.
Now more than ever, water-based stains offer a viable alternative to oil-based and other solvent-based stains.
Water-based stains penetrate deeper into wood than oil-based stains, resulting in deep, rich colors in only one coat. Manufacturers, professionals, and DIY users moving away from solvent-based products to water-based systems find immediate advantages...
Yes, you can. The resin systems for General Finishes Exterior 450 Topcoat and Milk Paint are the same.
General Finishes Outdoor Oil is an exterior-rated penetrating oil that is a wood maintenance preservative. It contains UV prohibitors, heat stabilizers & mildew prohibitors. Use Outdoor Oil for all exterior outdoor wood projects, particularly wood furniture.
