PRODUCT DESCRIPTION
Keeping safety for the user, your customers and the environment in mind, EFC-38 was developed to tackle your tough wood deck restoration projects fast. This unique formulation provides the strength necessary to strip most semi-transparent stains and sealers, dead, gray wood, mold, mildew and heavy accumulations of grime.

Unlike other per carbonate based cleaners, EFC-38 utilizes a proprietary blend of specialized ingredients which controls pH allowing you to melt off existing finishes without the need for excessive masking.

PRODUCT USAGE
For best results always use EFC-38 as instructed by the product label. Always perform a test patch to determine product suitability. EFC-38 is designed for use on all exterior wood.
First apply EFC-38 to a small inconspicuous area of about one square foot. Choose a spot on the deck, fence or siding that is well protected from the elements such as behind a bush or under a planter or mat on a deck. The idea is to choose an area that will present the greatest challenge.
After you have applied the EFC-38 to the test patch, allow to dwell 5 - 10 minutes and perform a scratch test. Using a tongue depressor (or a stick) scratch with light pressure back and forth over the treated surface. If the surface can easily be removed showing bare wood stop the test and note the dwell time. If the surface resists the scratch test allow an additional 5 minutes of dwell time keeping the surface wet with EFC-38 and perform another scratch test. When you are able to easily remove the finish with a scratching motion, note the total dwell time and rinse the surface thoroughly.
Depending on the age, type and condition of the finish you are removing, the dwell time can be anywhere from 5 - 15 minutes. The dwell time may be longer if there are multiple coats of finish that need to be removed.
PRODUCT APPLICATION
When applying EFC-38 be sure to take necessary masking precautions. Protect all adjacent surfaces that are not to be stripped. Protect vegetation from direct overspray. EFC-38 should not cause spotting on most plants. If plants do spot, this will only effect existing foliage. New growth will not be effected.
Apply product from bottom to top being careful to saturate the entire surface you intend to clean. When working on large areas, keep the product wet for the duration of the dwell time. If the product dries, it has quit working. For best results keep wet with a mist of EFC-38.
When cleaning a cedar home or log cabin treat the bottom three courses of an entire wall then work back treating the next three courses. Continue in this manner until you have reached the top of the wall. Keep the surface wet with an additional misting of EFC-38 as necessary.
FINISH REMOVAL
Perform a scratch test on the finish being sure to pick a spot that would likely be the toughest to remove. If the surface can easily be scratched off revealing bare wood beneath you are ready to rinse. If the surface is not easily removed, allow additional dwell time keeping the surface wet.
When you are ready to rinse the surface use a pressure washer at the lowest possible pressure. 600 - 900 PSI is ideal. Work following the same pattern you used when applying the EFC-38. Rinsing should be done in a sweeping motion, fanning your strokes at the beginning and end. After you have removed the finish from the entire surface you are working on give the surface a good rinse.
BRIGHTENING
After rinsing apply Citralic Brightener / Neutralizer to restore the woods natural color and pH.
