Install K-Kron units with installation clips or by securing the unit through the frame. In extreme and isolated cases, however, it may be necessary to secure a unit through the K-Kron finish. In such a case, predrill the casing before securing the unit to the wall, then fill any exterior nail holes with a complementary colored sealant. Fill the holes flush with the exterior casing surface to ensure that moisture cannot penetrate the wood. The K-Kron warranty will be void if the holes are not filled or if there are an excessive number of holes.
Formulas are available to color-match field purchased finishes.
Perform an annual inspection of the K-Kron finish. Repair where necessary, as stated above. Remove superficial dirt by washing with a garden hose equipped with a spray nozzle or a soft bristle, long handled brush. Remove heavier accumulations of airborne dirt, dust, smoke and salt spray with a mild solution of household detergent, such as Mr. Clean TM , Ajax TM , etc. Wet paint, tar or caulking compound may be removed with kerosene or mineral spirits.
