You can apply the brightener right away after cleaning. If there are puddles of water, try to broom those off before applying the brightener. There is no maximum amount of time you can wait, as long as you apply the brightener at some point before you stain.
Yes, you can usually wait up to about three weeks before the sun will start causing the wood to lost its natural color.
Short Answer: 150 square feet
HD-80 should be applied heavily at a rate of about 150 square feet per gallon. The stripper is designed to soften existing stain and sealers to a near liquid consistency. The amount of time this process takes depends on many factors. The type/brand of finish being removed, the number of “coats” or applications, the amount of direct sunlight the wood receives and the amount of time since the last application all play a major role.
HD-80 stripper is only active when it is wet. If the stripper begins to dry before the existing finish has softened enough, more stripper should be sprayed on to keep it wet. This will reduce your effective spread rate.
A high quality oil based exterior stain should be reasonably easy to strip. The “dwell time” or the amount of time the stripper needs to soften it thoroughly is usually about 15 min or less when the temp is about 70 degrees. Under these conditions you can count on that 150 square foot per gallon estimate.
If you are stripping several layers of a cheap water based, or worse a water reducible alkyd based product the dwell time is going to be much longer. Film forming products that crack and peel are often the most difficult to remove. Sometimes you have to keep the surface wet for up to an hour to completely soften all the layers to the point they can be gently power washed off.
If you are doing this work in the direct sun, on a breezy day you are going to have to apply the HD-80 several times in order to keep it wet that entire time. Each time you soak the surface your spread rate is going to be roughly 15o square feet per gallon, however your effective rate for the project might be half that or less.
This is the main reason professional contractors will almost always perform a scratch test to determine how long its going to take to strip the surface and better estimate how much stripper they will need to complete the job. For the DIY community we offer sample test kits so you can determine how easy your wood will be to restore.
We recommend using either the EFC-38 cleaner and mild stripper to remove outdoor wood furniture stain. Use also the HD-80 heavy-duty wood stripper. Then you would follow with the Citralic wood brightener and neutralizer.
It is okay if the wood is damp (with no puddles) or dry when applying EFC-38. The cleaner could become diluted if the wood has a lot of puddles. Wood that is in the direct sun can become hot to the touch. It is okay to mist the wood with a little water to cool it off before applying the EFC-38. This will help the cleaner stay wet and active longer.
HD-80 and EFC-38 are both very effective cleaners for concrete and hard surfaces.
Of course you want to follow all of the same safety precautions as when they are used for wood restoration.
Citralic Brightener/Neutralizer will effectively remove rust and other mineral stains from concrete.
For severe concrete stains, you can wet the area and then grind in some of the dry Citralic powder making a thin paste. Allow that paste to dry on the surface and then rinse away. Repeat as necessary.
It is easiest to use a pressure washer after the HD-80 has softened the existing finish. For larger jobs, it is a good idea to test the HD-80 first to be sure that it is going to effectively remove your finish. There are sample kits available for testing.
Yes. You neutralize with Woodrich Brand Citralic Brightener / Neutralizer before applying the new stain.
HD-80 is a heavy-duty wood stripper. It is effective at removing most semi-transparent deck stains and sealers. HD-80 is a caustic material. So care should be taken to protect surrounding vegetation such as grass and plants. We also recommend the use of protective clothing to protect the skin and eyes. Woodrich-Brand also manufactures EFC-38 which is a mild stripper that will effectively remove most oil-based semi-transparent deck stains and sealers. If you are not sure which product is best suited for your project, you can order a product sample kit. Then test them each to see which you prefer. You can also contact the Woodrich-Brand project support hotline at 636-288-8512 if you have questions before you order.
I believe that you would get better results with a paint stripper. This product works best for removing wood stains and sealers.
No. This product will not effectively remove that finish.
I am not sure this would be the best option for removing latex paint. You might consider trying the sample test kit first to be sure it is going to be effective. If the stripper is effective at removing the old paint, it will not effect the new application, as long as you rinse thoroughly and neutralize after using the stripper.
You should protect the plants from overspray, while applying the HD-80. You can either use a spray shield, or cover the plants while you apply the HD-80

This stripper is most effective at removing wood stains and sealers. This stripper will not remove latex paint. It will remove some oil based paint. There is a sample test kit available.

Yes! Wear protective gear when using this product. Read all MSDS and first aid material completely before beginning. Knowing what to do if something goes wrong while using HD-80 will help minimize the risk of serious injury. Keep animals away from areas (confined in home is best) where HD-80 is being used.

Not only will the end result be less attractive, most assuredly the finish you apply will fail prematurely.
Use Citralic Brightener/Neutralizer to brighten up the wood. This helps to neutralize any sodium hydroxide after stripping. Citralic also returns the wood to it’s natural color.
In most cases HD-80 will easily remove mold and mildew. If there is an extreme build up of mold and mildew you can add one cup of bleach per gallon of product. Please note that bleach can damage the wood and should be rinsed as soon as possible. (NEVER mix bleach with EFC-38)
The best method is the dry scratch test. Use a stir stick or similar item to scratch at the finish. When it can easily be removed down to bare wood it is time to rinse.If any stain is still present, reapply HD-80 again until it is easily removed. We recommend that you perform several scratch tests in different areas prior to rinsing.
Depending on the coating you are removing, it can take from just a few seconds to as much as 15 minutes per layer of finish being removed.
The coating will change color and the wood will turn dark. Use a scratch test to determine when the existing finish has been fully emulsified and is ready to strip.
No. HD-80 is stable in solution and has a long shelf life. You can premix it with water into a concentrate for use later. Just dilute it in order to meet your needs.
Mix 8 oz (1/2 LB) per gallon of water for full strength. In dry measure that is about 2/3 cup. You can then dilute it up to 4 to 1 with water depending on the job at hand.
