Linseed Oil Putty 682 is a high quality putty in glazier quality, produced from pure linseed oil and selected chalks. The product is used for puttying of windows, repairing of rabbets and for filling of primed wood, indoor and outdoor. Also suitable for filling of nail holes. Linseed Oil Putty 682 has a high and protective adhesion to glass and wood. The putty is tixotropic and easy to apply.
Directions for use
Preparation: The surfaces must be clean and dry before application of the putty. Porous surfaces like wood, must be primed, so that the oil in the putty does not penetrate into the wood. If the oil in the putty penetrates into the wood in high degree, the putty may become dry and hard and can crack. The wood shall however not be primed more than the putty can get a grip in the surface of the wood. Shellac and acrylate primers shall not be used. Oil based primers possibly containing mineral spirit or other solvents must be completely dry and evaporated. Remaining solvents can create bubbles in the surface of the putty
underneath the paint.
Application temperature: Can be applied at temperatures from 5 °C to 40 °C. The minimum temperature of the day must not be below 5 °C during curing.
Application: Linseed Oil Putty 682 shall be homogenized before usage. Free oil film on the top must be incorporated into the putty. The putty is applied with a putty knife. If used indoor, it is important to assure sufficient ventilation around the putty (windows must be placed above floor level and in suitable mutual distance). This shall assure that a thick enough skin is formed which can support the painting process. When used outdoor, it must be assured that the putty is not exposed to heavy rain before skin formation. If possible it should be used in dry weather conditions, but never in direct sun light.
Curing: The putty forms a skin typically after 2-4 weeks. The putty shall be protected against further curing by painting it over.
Paint: Linseed Oil Putty 682 must be painted. Using pure linseed oil paint, it is possible to paint the putty – carefully – immediately after puttying. Using alkyd oil paints, acrylic paints etc, the putty should be painted as soon as it has dried up sufficiently on the surface to withstand the pressure from the brush and paint so the putty surface does not
become deformed and wrinkled. If the putty stands without paint for a too long period, it may develop cracks on the surface from too severe drying. Sufficient drying time is typically 2 – 4
weeks but can vary according to weather conditions. It is recommended to paint 1 – 2 mm onto the glass. The paint shall protect the putty against sun and rain and further drying. Therefore it is recommended to use a paint with high water resistance properties
The putty surface: The putty shall be protected from outer effects. However, many factors can disturb the surface both before and after painting. Linseedoil putty can have a smooth surface but can in
many situations get a wrinkled surface. Wrinkles come because the linseed oil cures and makes a skin which is fragile even to the smallest disturbances. A putty with wrinkles is not a sign of a failure in the putty but is a phenomenon which can come from moving the window frames, mounting, wind, finger marks or even just changes in humidity and temperature between in and out door. Wrinkles can occur in sections or on the entire surface.
Cleaning: Uncured putty can be cleaned with paper or dissolved with White Spirit.
