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.
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.
I would recommend starting with the sample kit to test for efficacy.
Yes, that is the fastest way to apply.
This product will not remove paint that is in good condition. If the aluminum windows are well aged and heavily oxidized, the cleaner may remove some of the surface oxidation. Thus, leaving what looks like either clean or faded areas.
No, this product is not an effective paint remover.
No, HD-80 would be a better choice for that finish removal. Sample test kits are available to help you determine the required product dwell time.
Yes. EFC-38 is a perfect choice for restoring the weathered exterior of log cabins.
This product is designed to be mixed with water and then applied at “full strength” using a pump-up garden sprayer. Injecting the solution using a power washer would dilute the product too much.
It depends on what type of stain it is. This product will remove most true oil based stains and sealers. We also offer a Heavy Duty Stripper called HD-80, for solid stains and other hard to remove finishes.
HD-80 can be used to clean concrete, vinyl siding, brick, Trex and PVC. You can also use EFC-38 as a safe roof cleaner
Not harmful for pets if you use common sense and handle it properly. EFC-38 was designed in order to be safe for the user and for the environment.
Nope, unless they are extremely delicate such as lacy ferns or soft petel flowers and they are in direct sunlight. In such cases the water causes the sun to burn the plants. Shake the excess water off to prevent burning.
No, EFC-38 finishes off close to neutral. As long as you rinse well you do not have to use a neutralizer. You may wish to brighten that extra bit to help make your work stand out among the competition.
Use Citralic Brightener/Neutralizer in order to brighten up the wood.
In most cases EFC-38 will easily remove mold and mildew. You should see it work drastically when it comes in contact with mold or mildew. If there is an extreme build up of mold and mildew you can apply additional EFC-38 to fully eradicate the infestation. (NEVER mix bleach with EFC-38)
If you are working on a solid color stain you should be using HD-80. EFC-38 is only going to make the finish nice and clean.
It is going to do it’s job in about 15 min. If you have a stubborn finnish you may allow for additional dwell time keeping the surface wet.
The coating will change color and any mold or mildew should activly fizz up and turn white. Use a scratch test to determine when the existing finish has been fully emulsified and is ready to strip.
Use EFC-38 within a couple of hours from the time of mixing. Beyond that, it loses its effectiveness as a stripper. You should also take care to keep the powder dry when you store it. The shelf life of the dry powder is 6 months so be sure to keep your supply fresh.
Mix 8 oz (1/2 LB) per gallon of water for full stregnth. In dry measure that is about 2/3 cup. You can then dilute up to 4 to 1 with water depending on the job at hand.
EFC-38 works on removing oil-based finishes such as TWP, READY SEAL, WOLMAN, OLYMPIC, CUPRINOL and other semi-transparent finishes.
EFC-38 contains a percarbonate, but is not like a straight percarbonate cleaner. EFC-38 was designed to remove aged and failing oil based wood finishes. It will perform many jobs that a percabonate cleaner can not do. EFC-38 is safe to use and makes an excellent tool for wood restoration.
