Helps Control Heat and Moisture
Lumber is processed in dry kilns to remove excess moisture. High heat is used for this process. Temperatures in the dry kiln average 180°F. The vapor pressure of water at this temperature is 7½ pounds per square inch. The difference in pressure between the inside and outside of the dry kiln causes heat and moisture to squeeze through the walls, doors, etc. Lumber Kiln Coating provides a rugged barrier to help control heat and moisture loss within the dry kiln.
Heated air laden with moisture rises to the ceilings in dry kilns. lumber kiln coating retards this moisture from penetrating the ceiling, walls and decking of dry kilns. By minimizing decay and rot in wood roofs and decking, lumber kiln coating substantially reduces expensive structural repairs or replacements. Proper application of KILN SEAL is beneficial in helping keep dry kilns operating efficiently and continuously.
Lowers Fuel Costs
KILN SEAL forms an air-resistant, moisture and waterproof barrier. Controls outside air from coming through and retards moisture and heat from escaping. Steady heat is maintained, affecting savings in fuel costs.
Heat and moisture ratios within dry kilns are more easily and effectively controlled with KILN SEAL. With a steady temperature maintained, lumber is cured more rapidly, steadily and efficiently.
Is Easy To Apply
KILN SEAL is ready to apply as it comes from the pail or drum. No mixing or thinning is required. Before applying lumber kiln coating, all cracks should first be sealed with MIGHTYPLATE PLASTIC CEMENT. KILN SEAL is then sprayed or brushed on the interior walls, decking and ceiling. Apply as recommended in "KILN SEAL Coverage."
KILN SEAL must not be applied to Dry Kiln fans, fan blades, thermostats or other mechanical operating parts.
KILN SEAL is not recommended for use in Kilns processing Brick or Tile!
KILN SEAL Coverage
It is recommended that 1½ to 2 gallons KILN SEAL be used for each 100 square feet of interior surface. The average Lumber Dry Kiln requires from two to three drums KILN SEAL. If surface is very porous (concrete block or concrete construction) a minimum of 2 gallons per square is recommended, and 2½ gallons may be necessary to obtain a complete VAPOR BARRIER.
After application of KILN SEAL, it is advisable to leave Dry Kiln open and inoperative for two days. If this is impossible, Dry Kiln may be used at once. The immediate use may cause small blisters to develop on KILN SEALED surface but these soon disappear. KILN SEAL is uniquely self-healing. Inspection should be made, however, and if any pinholes have developed, a touch-up application completely reseals.
The moisture and vapor barrier properties of KILN SEAL are actually increased by the approximate 180° Fahrenheit heat used in most Lumber Dry Kilns.
