This document contains multiple sections that address a variety of topics. Proper wood preparation and measuring the moisture content of the wood prior to application are the two most critical steps to getting the best results. *See the WOOD PREP and MOISTURE CONTENT sections of this document.
The first requirement for proper wood preparation is that the wood is clean and bare, free from any previous product. If your wood is:
Huemiller Combo Stain & Sealant is an oil-based semi-transparent stain. Since oil and water do not mix, the most important, requirement for successful Huemiller Combo Stain & Sealant application is to ensure the wood is completely dry. This can NOT be definitively determined just by touching the wood or by simply allowing a certain number of hours, because different regions have higher humidity, colder temperatures, variable weather conditions, or the wood may be very porous and holding onto moisture longer than a denser wood.
Huemiller Combo Stain & Sealant is intended to be a two-coat application, and the representation of tones above and on the Huemiller Combo Stain & Sealant website is indicative of two coats of Huemiller Combo Stain & Sealant. However, because Huemiller Combo Stain & Sealant is not a paint or coating the covers the surface of the wood, but rather penetrates down into the wood pores, there are some projects where the wood simply will not take a second coat, including brand new, smooth-milled wood (such as deck boards or raw furniture), as well as some exotic hardwoods. Both of these wood categories are very dense, and it takes several years for dense wood to open up enough to take a second coat. Doing a pre-treatment with a 50/50 bleach-water solution (spray on, let sit for 30 minutes, and rinse well) can serve to open up those wood pores a little. If this is done, the wood must be allowed to dry down to 12% or less before applying Huemiller Combo Stain & Sealant.
Two Coat Verification Test Method:
Not sure if your project will take two coats? Here is how you can tell: After applying the 1st coat and allowing 1 hour to dry, then apply a few drops of Huemiller Combo Stain & Sealant in a few test areas. Let those drops sit undisturbed for 30 to 45 minutes, and then wipe your fingers or a paper towel across test areas. If you see nothing at all or just clear oil, the pigment has penetrated in and the wood is ready for a second coat. If you see color/pigment when you, you will have to wait a year or more for subsequent application.
Huemiller Combo Stain & Sealant can be applied with any tool you are comfortable with:
CLEAN-UP: tools can be cleaned with mineral spirits when finished.
If using a sprayer, do not use on a windy or breezy day, as overspray may inadvertently travel to nearby structures, vehicles, windows, stonework, or furniture, and it is difficult to remove if not caught early. You may want to wait for a less windy day.
Cover all nearby plants and vegetation with plastic drop cloth before applying Huemiller Combo Stain & Sealant to protect against drips and overspray. Be cautious of extreme heat- plastic drop cloths on hot summer days can burn and/or kill vegetation and plants.
Prior to staining, you can generously wet down any nearby concrete or stone or other surfaces. Because oil is lighter than water, this gives you a window of opportunity to address any spills, drips, or overspray, as the water will delay the penetration of Huemiller Combo Stain & Sealant into a porous surface. Rinsing areas again after staining washes away the floating oils. Don’t allow water to evaporate or Huemiller Combo Stain & Sealant can stain concrete.
It is always recommended to protect skin and eyes when working with any chemical products.
