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.
GF advises extra care and prep when applying any finish over laminate surfaces because they are specifically designed not to mar and therefore they are not very "sand-able", making adherence difficult.
In addition to this non-permeable surface factor, General Finishes Gel Stain is an oil-based product, and it is more difficult to obtain proper drying characteristics over a dense manufactured surface such as laminate. Gel stains, as all wood stains, were formulated to go over raw wood which has an "open" surface and can absorb some of the stain.
Newly formulated Enduro Stain Blocker is General Finishes' revolutionary water-based stain-blocking primer that now provides improved sandability and advanced performance for interior AND exterior projects. It can protect pigmented finishes from stains, dyes, and wood tannin bleed-through.
You can apply Gel Stain to MDF, stained surfaces
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...
Haze (the technical term is blush) is caused by too many coats applied too quickly. A recoat time of 12 hours is not enough dry time when applying over an EXISTING finish. To remove the blush or haze, you can either wipe the area with a strong solvent, like xylene or lacquer thinner, or you can try sanding out the haze and then reapply the topcoat.
This response is true of prepping and existing finish on furniture, but kitchen cabinets are more problematic because they are work areas where grease, steam, food splatters and oil from hands are common. Prep is basically degreasing and abrading the surface for better adhesion. Oil or substances on hands really show up on a failed re-finish around doorknobs and hands if the surface is not cleaned thoroughly.
Recommended for use on Interior/exterior wood applications such as raw wood, existing finishes, and MDF.
This is General Finishes' most advanced primer, and it is the most expensive. If bleed-through is NOT a concern, use one of our other physical primers: Enduro White Undercoat or Enduro Deep Base Primer.
