Rustins Professional Wood Filler is a two-part filler that provides a strong long lasting repair for all interior and exterior wood work. It hardens within 30 minutes at ambient temperature and produces a tack free surface. It is easy to sand and readily accepts Rustins Wood Dyes as well as Rustins paints and varnishes. Once fully hardened, it can be sanded, drilled, machined and planed and is particularly useful for carrying out repairs to the edges on joinery where high strength is needed. It is also suitable for marine applications.

• Preparation
  The surface must be clean, dry and free from all traces of oil, grease and dust. To provide good adhesion to timber, key the surface by lightly sanding with a medium grade of sand paper.
  
• Application
  Mix the filler with the hardener on a non-porous surface using an amount of filler the size of a golf ball to a pea-sized ball of hardener as the mixing ratio. Mix thoroughly until an even colour is obtained. Do not prepare more than is required as any excess will be unusable after 10 mins.
  
• Applicator
  Mix using the applicator provided or use a putty knife but apply using the applicator provided. Apply sufficient filler so that it is proud of the surface to allow a continuous smooth surface to be obtained by sanding.
