Installing Parquet Flooring

First thing to consider is sub floor preparation. The flatter the the floor the less chance of gaps and obviosly the flatter the finished floor will be. Concrete floors can be leveled with self leveling screed like stop gap 3oo or ply for wooden floors. All floors should be tested for moisture and moisture should be lover than 4 %. Mark out the border with a chalk line always allow for exspansion gap of 12mm and block border including inlay. Then glue out and lay parquet floor blocks, always lay out a spine first consisting of two rows of blocks going down the length of the room make sure these are presion laid . Then allow a few hours to dry please mark sure these are striaght. Always glue out to chalk line but lay blocks over the line ready for being cut. After you have finished laying blocks leave to dry . Then mark out exactly where border is going and cut out with a festool skill saw or normal skill saw . Festool saw is reccomend as it doesn't chip blocks, then glue out and lay border. Thats it for laying the floor onto finishing, only thing i will say is if laying new floor use a polymer adhesive like silka or if it is a old floor then use a bicthem glue like f21 it will react with the old bitchem.
