While Gel Stain can be applied over an existing finish, it was originally engineered for raw wood surfaces. We prefer applying the Gel Stain over a slip coat of mineral spirits instead of topcoat as shown in this video, "How to Apply Gel Stain to Raw Wood"

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.

There are several reasons to choose Dye Stain. Here are a few.

It is normal to see a bit of stain on the brush when applying the first coat of topcoat. Topcoats often pull a bit of color on the first pass, but good preparation will minimize this.

To prepare open grains woods such as raw Oak for a water-based stain, we recommend sanding with 180-grit followed by no more than 220-grit sandpaper.

All bright white paint will yellow slightly with time, even without topcoat. You have probably tried to touch up white woodwork in your home after several years and noticed that the new paint is brighter.

But white and light paints can react if clear coated with a waterbased finish; water-based topcoats are reactive and may draw out substances in the wood such as tannins, dyes or unknown substances in existing finishes causing the topcoat to yellow. This is an industry-wide issue and can happen right away, years later or never.

The most critical part of finishing a piece of furniture happens before you open a can of stain or paint - it starts with the sanding. Sanding is critical to creating a smooth surface. Use the following sanding sequences for new wood:

PAINT

For wood that is going to be painted, use 120-grit, followed by 150-grit.
