The best type would be an exploded tip nylon brush for use with water or solvent based wood paints.
Yes, 896 colorant is compatible with Hemp Shield. Only care should be taken that deep base (solid color tints) many have slower dry times than normal.
Mill Glaze is a common problem with mill cut wood which is manufactured using a dull planning blade. The surface of the wood becomes heated bringing the wood tannins and acids up to the surface, heating and, than sealing the wood. The wood will then not accept stains. There are two basic ways to deal with mill glaze. The first is exposure to weather which will open the wood naturally over time. The wood may than be stained. The second method is using
a commercially available Wood Glaze Remover. These materials are a combination of water, solvent and wetting agents which dissolve the glaze and open the wood for staining. If you do not remove the glaze and attempt to wood floor stains, the wood will stain unevenly and you will have blotches in the look of the deck.
It is not possible to give a definitive answer because projected life is dependent on the “where” and to “what” the product is applied. However, weatherization tests data can be used to estimate the projected life compared to competing products. You can review our test data on the Hemp Shield website. “Unofficially” we expect the longevity to be at least 3-3.5 years.
Steve Neiswander the Vice President and inventor of the Hemp Shield formula, explains it best: “As coating chemists our research lab decided to throw out all the stops, when we developed Hemp Shield. We went to the very best technology available in the market. We used UV absorbers, typically found in automotive coatings, in our deck stains, so we could reduce the amount of discoloration in the wood. We chose biocides that are brand new to the market,
which are encapsulated, so rather than releasing a large quantity of biocide in the environment at one time there is a time release on the biocide, keep it just as effective without damaging the environment, this new biocide has now been approved in California. We also developed the lowest VOC coating we could which means it has the least amount of Volatile Organic Compounds, far below what the legal limits are in any state in the United States. We think that this coating is the “greenest” deck finish on the market today” This along with the synergistic benefits of using emulsified Hemp Oil, truly differentiates Hemp Shield from traditional wood floor stains sold in today’s market.
Yes, Hemp Shield will produce any color with a minimum order of 50 gallons.
The tints used in Hemp Shield add no VOC to the product since Hemp Shield uses a stir in modified Trans oxide pigment rather than a conventional tint base.
Hemp Shield is dry to touch in 1 hour, serviceable at 77F/50% relative humidity in about 12 hours with full cure in 48-72 hours. Hemp Shield contains no alkyd resin so it dries strictly by evaporation and therefore dry times are dependent on relative humidity.
Any former sealant traces have to be gone from the grain of the wood before HS will work properly. The surface should be clear of anything blocking the grain either by using a deck cleaner, power washing or sanding (or any combination of these actions) so that stain colors can penetrate the wood unobstructed.
“Coverage rates” are a simple calculation. The volume of solids of the coating times 1,604 equals the square feet at one mill dry film thickness. So if you’re coating has 50% volume solids the coverage rate is 802 square feet at one mil. If you are applying at .5 mil then your coverage rate is 1604 square feet. This is independent of any penetration into the substrate. The penetration into wood varies greatly with the species of wood, and the porosity of the surface.
The porosity may be affected by the cut of the grain, the amount of weathering of wood, and the amount of moisture in the wood. Hemp Shield is a blend of emulsified Hemp Oil and flexible acrylic polymer. The formula contains wetting agents to lower the surface tension and help pull the polymer as deep into the wood as possible to not only coat the surface but fill the wood cells with the polymer, UV inhibits and Hemp Oil. This stabilizes the wood from UV degradation as much as possible. Hemp Shield has higher volume solids than most products on the market. Part of the reason for Hemp Shield superior performance is the increased solids. We are not filling the wood with solvent or water; rather, we are filling the wood with oil and stabilizing polymers.
