HOW TO LOCATE DRY ROT
 Tap questionable areas with a hard instrument and listen for
hollow sounding dead spots. Probe suspect areas with an ice
pick or sharp knife. Check areas where fresh water is likely to
accumulate. Particularly check the following: Spar checks,
hatches, deck seams, transom, companion slides, checks in
planking, toe rails, exposed end grain, stem, ribs, and stringers.
AMOUNT REQUIRED
For complete saturation and ultimate strength, in average type
rot, it will require a volume of "GIT"-ROT approximately equal to
half the volume of the rotted wood.
TIME AND TEMPERATURE
The optimum temperature for applying "GIT"-ROT is between
50Deg and 70DegF (10Deg and 21DegC). Only mix small batches (no more
than 4 oz.) since the larger the quantity the greater the reaction
and the faster the cure. After adding 1 part "B" to 3 parts of "A",
shake vigorously for at least one (1) full minute (TIP: use a
watch while shaking the bottle.) Once the two parts have been
thoroughly mixed, a thermal reaction will begin to occur.
Penetration is best immediately after mixing. When working in
temperatures over 70DegF (21DegC), chill "GIT"-ROT overnight. At
70DegF, properly applied "GIT"-ROT solidifies into a tough resilient
mass overnight. Allow one week for ultimate strength. Cold
temperatures will slow the cure. When painting, check
compatibility with paints.

PROVIDE RESERVOIRS
The mechanics of the actual treatment will vary for each case
depending upon location and construction. Where rot is deep
into a large member it is advisable to drill a staggered series of
overlapping holes approximately 1/4" in diameter, 2" apart,
slanting downwards. This will expose the necessary end grain
and provide reservoirs for the penetration as shown here. In areas where sections of rot contain extensive
holes where wood fibers are actuallymissing, it is recommended to mix sawdust with "GIT"-ROT and
use it as a fill material. In areas such as transoms, stringers, and
balsa core decking, drilling thru the fiberglass surface may be
necessary. For transom repairs, you may drill vertically down
through the transom, and then pour in "GIT"-ROT. For decking, drill
thru the surface to treat the wood underneath. Holes left by
drilling may be filled with a mixture of dry saw dust and "GIT"-ROT
or a marine repair epoxy compound.
PENETRATION
Capillary action is the principal on which "GIT"-ROT works.
Therefore, the most expedient way to apply the "GIT"-ROT is into
the end grain of the wood wherever possible. To avoid trapping
air in the middle of the rot always start at one end or on one
surface and work progressively along. A considerable amount of
patience is required during the actual penetration until complete
saturation is achieved. This is determined when the reservoir
holes fill and remain filled and the surface remains shiny.
DAMPNESS
"GIT"-ROT will eventually cure in damp wood. However, "GIT"-ROT will not displace water. So wet wood cannot be fully saturated. Any reduction in the amount of "GIT"-ROT simply reduces ultimate strength. Dry the affected area as much as possible. Soaking with acetone will assist drying; however, be cautious of fire hazard. CAUTION: Reaction between part A and B will produce heat. Do not use in high temperatures. Avoid all external additional heat sources.
