Lesson 1Parquet patterns: geometry, material yield, and visual effects of herringbone, chevron, and mosaicYou will study how herringbone, chevron, and mosaic patterns affect material yield, layout complexity, and visual impact. Learn to plan board sizes, waste factors, and pattern direction to suit room shape and light.
Herringbone geometry and layout fundamentalsChevron angle choices and directional emphasisMosaic and panel patterns for small spacesMaterial yield, offcuts, and waste calculationsPattern choice versus room proportions and lightLesson 2Physical and mechanical properties of common parquet species: oak, maple, walnut, ashThis section reviews density, stiffness, and movement behaviour of oak, maple, walnut, and ash. You will compare their structural performance, machining response, and suitability for different parquet formats and traffic levels.
Density and weight differences among speciesElasticity, stiffness, and deflection under loadWear layer performance in solid and engineered parquetMachining, splintering, and edge stability by speciesSpecies suitability for residential versus light commercialLesson 3Finish types: penetrating oils, water-based polyurethane, solvent-based polyurethane, hardwax oils — composition and performanceHere we compare penetrating oils, water-based and solvent-based polyurethanes, and hardwax oils. You will understand their composition, curing, appearance, and performance to choose the right system for each project.

You will assess risk of gaps, cupping, and adhesive failure under varying humidity.
Radial versus tangential shrinkage by speciesEngineered versus solid stability comparisonsMoisture limits for concrete subfloors and slabsVapor barriers, primers, and adhesive selectionSpecies choices for high humidity or slab‑on‑gradeLesson 5Durability and scratch resistance ratings; Janka hardness and impact on family living roomsHere we relate durability ratings and Janka hardness to real family use. You will learn how denting, scratching, and wear appear in living rooms, and how to balance hardness with comfort, acoustics, and budget.

Learn expected service life, sanding limits, and how species colour and grain influence visible repair results.

You will plan layouts that respect manufacturer limits and minimise on-site problems.

You will compare film-forming and penetrating systems for different use and maintenance profiles.

You will use decision criteria covering durability, warmth, cleaning effort, style, and long-term flexibility.

You will learn to predict oxidation, staining risks, and colour stability under light and daily use.
