Lenmar’s 1C.5300A MegaVar^TM Catalyzed Vinyl Sealer is a versatile, non-yellowing, field catalyzed sanding sealer offering numerous benefits for the professional woodworker.  Once catalyzed, this fast drying VOC & HAPS compliant sealer offers an exceptional amount of solids for initial build, seals and fills most porous wood species in a single coat, and sands easily.  The high solids content helps lock in and protect stained wood from being marred when scuff sanding.  This sealer also offers strong resistance to cold checking and safeguards against cracking.  If desired, this sealer can serve as an excellent foundation for use under 1D.33X, 1D.35X, 1M.430X or 1M.530X series or other Lenmar precatalyzed lacquers or conversion varnishes.  Lenmar’s 1C.5300 field catalyzed sanding sealer requires the addition of 4 ounces of 1A.622B Catalyst (3%) per gallon.  Once dry, the sealer should be sanded with 320-grit sandpaper.  Only catalyze sufficient amount of sealer that will be applied in an 8-hour period.
