Koopmans Nylostop Wood Rot Filler

Nylostop is a practical, odourless two-component epoxy repair product from Koopmans for filling holes in wood, steel and concrete or stone. On the Koopmans website it is now called Nylostop Houtrotreparatie (wood rot repair); it is the same product as Nylostop Houtrotvuller (wood rot filler).

What you use it for

For wood rot repair, for example on window frames and window sills, and for repairing damage in concrete and bluestone. Also suitable for repairing wooden furniture, bonding all kinds of building materials and filling seams and corner joints in steel. Can be used indoors and outdoors. Not intended as a filler: repairs from about 5 mm.

Properties

Solvent-free epoxy resin that does not shrink as it dries, bonds strongly to almost any surface and sands well once cured. Mixed, the mass is beige to cream.

Application

Remove all paint in and around the repair down to the bare surface; the surface must be clean, grease-free and dust-free. On wood, cut or rout out rotten parts, at least 10 mm into the sound wood. Mix equal parts of components A and B on a mixing board or smooth plastic sheet until smooth and apply with a filling knife. First spread a thin layer on the surface, then fill the repair into the still wet layer, finishing slightly proud. Working time about 30 minutes, cured through after about 5 hours, sandable after about 24 hours (at 20 °C). Apply above 5 °C; the wood must not contain more than 18% moisture, stone no more than 4%. Do not thin. Can be painted over after about 24 hours.
