Teknos Teknofill 5001 Acrylic Fine Surface Filler

Surface defects, checks and cracks around knots can be visually unattractive and disrupt subsequently applied coating systems, leading to localised breakdown.

Teknofill 5001, Fine Surface Filler is a single component, water-based, white acrylic filler which, when applied by palette knife, fills and levels surface defects.

It has excellent sanding properties and dries in around three hours to a smooth fine surface ready for opaque topcoat application.

It is particularly recommended for use around knots, where it enhances resistance to tannin migration.

Anything in excess of 1 mm deep should be filled with a two pack wood filler.

Used in combination with Anti Stain Aqua 5200, provides enhanced resistance to knot staining.
