Prior to covering a wood airframe, it is critical that the wood is sealed to protect it from the deterioration from exposure to moisture. Stewart Systems EkoSeal is an excellent choice for this application. As with our other products, this wood sealer is non-hazardous and non-flammable. It is a single-part, waterborne polyurethane and leaves a beautiful, glossy finish. It can be ordered in clear or satin.
We also offer a sanding wood sealer for applications where filling and sanding is necessary. After sanding, a coat of standard wood sealer or a topcoat should be applied for a permanent seal. EkoSeal can be applied by spray application, brush, or roller. EkoSeal provides an excellent surface for the application of EkoBond on fabric covered aircraft. For areas where fabric terminates without an overlap joint, EkoSeal should be lightly scuffed for best adhesion.
