induro® GP Seal Floor Sealer and Primer

This state-of-the-art wood warming waterborne floor sealer and primer is formulated to enhance the natural appearance and grain of all types of wooden flooring. Use before overcoating with induro® XL1XL2, NATRO%, XLA or SPORT waterborne flooring lacquers for an extremely strong but flexible varnish with excellent clarity and strong chemical and mechanical resistance. Unlike other waterborne floor sealers available this product does not require the addition of an extra crosslinking additive.

If sealing a particularly oily or waxy wood such as tropical hardwoods, use induro® ISO Seal shellac-based sealer.

Floor Staining

Morrells standard Light Fast range of stains give excellent grain definition and overall colour. Due to this range being spirit based (fast drying), care should be taken on application not to stain too large an area at once as this could lead to a patchy appearance once the stain is dry.

  1. Stain should be applied by brush/rag or mohair pad
  2. Remove excesses with a clean rag

It is important to remove as much excess floor stain as possible so as not to create a film as this could result in poor adhesion of subsequent coats of floor lacquer.

Stains intended for other uses i.e. decking, fencing, garden furniture etc should not be considered for floors as these will contain water-repelling properties, and therefore water based floor lacquers would not adhere to these stains.


Prior to starting the sanding process the floor should be checked for any protruding nail or screw heads and these should either be removed or countersunk. All wooden floors requiring a varnish finish will have to be sanded. Newly laid floors are sanded to achieve a nice level floor and old floors are sanded to remove existing finishes and to level out worn and heavily used areas.

Sanding will have to be carried out in several grit stages and this will be dependent on the unevenness and general condition of the floor.
