Instruction Example 7.5.: Finishing and Sealing of Parquetry

Practising of parquetry finishing and sealing irrespective of the type of parquetry

Material

Parquetry sealing lacquer, thinner, joiner’s putty

Tools

Broom, brush, paint roller, abrasive paper, sandpaper block, pushing scraper, grinder

Auxiliary accessories

Bucket, can

Required basic knowledge

Handling a grinder, working with parquetry sealing lacquers and knowledge of their properties, coating methods

Sequence of operations	Comments
1. Once again cleaning parquetry thoroughly with broom, detecting small faults.
2. Reworking faulty spots, such as cracks, knots and defective edges with the help of scraper and joiner’s putty.	If - in spite of the careful selection of the parquetry-fillets - there should be deeper holes or defects, the joiner’s putty is applied in layers.
3. Smoothing the floor with the grinder in circular motions until an even and plane surface is achieved.	When grinding, make sure that no corrugations appear.
4. Sweeping smoothed floor carefully.	Do only walk with soft and clean shoes on smoothed floor.
5. Putting on the first layer of the sealing lacquer - along the edges with brush, in the middle with paint roller.	When applying the lacquer coat make sure that no foreign bodies, such as shavings or rough particles of dust, are left under the lacquer coat.
6. After the first coating has dried, smoothing minor imperfections such as wood fibres that were put upright by fine-grained abrasive paper. Removing grinding dust carefully.	First coat will have dried after approximately 24 hours.
7. Applying two other coats of sealing lacquer at the appropriate intervals.	If required, unevennesses can be smoothed again here and there.
8. Cleaning the working place.	Painting tools are washed in thinner.
