How to use Git Rot
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 50 and 70F (10 and 21 C). 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 70 F (21 C), chill Git Rot overnight. At
70 F, 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 actually missing, 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.
