458-1288 Reslack Polyester Clear Sealer

458-1288 is used as a sealer for all types of closed grain finishes and is especially recommended for surfaces where it is difficult to perform a proper sanding.

Apply to MDF after sanding substrate with 120/150 grit paper. To obtain maximum adhesion over MDF and for use over wood, application of the urethane washcoat is required. After curing, the washcoat should be sanded with 240 grit paper.

Agitate material before use and while adding accelerator and/or hardener per mixing ratio. To ensure product consistency, the mixed material should be agitated at all times. Times between coats for wet on wet spray are about 20 minutes so the sealer will gel in order to give good intercoat adhesion. The topcoat must be applied within 8 hours following sanding of 458-1288 Reslack Sealer Thix. It may be overcoated with ora Verde Chiaro 436-48XX, ora Verde Acrilico 436-38XX or Reslack Clear 458-1290.

With profiled doors, care must be taken with sanding of the primer to avoid sanding through on sharp edges. Complex profiles or profiles with sharp corners may cause difficulties in obtaining an effective prime coat of even film thickness. In these cases, profile design must be discussed with your technical representative. Maximum film build of 458-1288 should not exceed 20 mils dry.
