Lesson 1Parquet designs: shapes, wood use, and looks of herringbone, chevron, and mosaicYou study how herringbone, chevron, and mosaic designs change wood use, how hard to lay out, and how they look. Learn to plan board sizes, waste amounts, and design direction to fit 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 2Strength and qualities of common parquet woods: oak, maple, walnut, ashThis part checks weight, bend strength, and swelling of oak, maple, walnut, and ash. You compare how they hold up, how they cut, and if they fit different parquet sizes and busy areas.
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 kinds: deep oils, water poly, solvent poly, hardwax oils — makeup and how they workHere we look at deep oils, water-based and solvent-based polyurethanes, and hardwax oils. You understand what they are made of, how they dry, look, and work to pick the right one for each job.
Penetrating oils: solids content and curingWater‑based polyurethane layers and additivesSolvent‑based polyurethane and film hardnessHardwax oils: wax fraction and open timeVisual look: sheen, depth, and grain highlightingLesson 4Water swelling and size steadiness by wood type; good for concrete basesHere we check water swelling and size steadiness for main wood types and how it changes putting over concrete. You judge risks of gaps, bending, and glue fail under different wet air.
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 5Toughness and scratch hold levels; Janka hard test and use in home sitting roomsHere we link toughness levels and Janka hard test to real home use. You learn how dents, scratches, and wear show in sitting rooms, and balance hard with soft feel, sound, and cost.
Understanding Janka hardness test proceduresHardness versus denting from furniture and toysScratch resistance from pets, sand, and chair legsBalancing hardness, comfort, and acoustic behaviorSpecies selection for busy family living roomsLesson 6Care and refinish ways for each wood typeYou compare how oak, maple, walnut, and ash take cleaning, wear, and refinish. Learn how long they last, sand limits, and how wood colour and lines change repair looks.
Routine cleaning needs by species hardnessSurface wear patterns and gloss loss over timeSanding limits for solid and engineered parquetColor change impact on patch and board repairsRefinishing intervals in typical home conditionsLesson 7Design lay limits: board sizes, tongue-groove way, and cut space needsThis part tells how design pick limits board sizes, tongue-groove way, and cut space. You plan lays that keep maker rules and cut site troubles.
Board length and width rules for herringboneChevron angle, leg length, and factory millingTongue‑and‑groove direction and reference linesExpansion gaps and border framing strategiesCutting allowances and waste for complex layoutsLesson 8Finish qualities: rub hold, yellow turn, VOCs, air pass, recoat ease, fix easeThis part shows how finish makeup drives rub hold, yellow turn, VOC out, air pass, and fix ways. You compare coat and deep systems for different use and care needs.
Abrasion resistance and traffic class ratingsYellowing behavior of oils and polyurethanesVOCs, indoor air quality, and regulationsFinish breathability and moisture bufferingRecoatability, spot repair, and blending limitsLesson 9Picking wood type, design, and finish for customer wants: toughness, warm feel, clean ease, classic look (pick list guide)This part gives a clear way to match wood type, design, and finish to customer hopes. You use pick rules on toughness, warm, clean work, style, and long change ease.
Clarifying client lifestyle and traffic patternsPrioritizing durability versus visual warmthCleaning effort, stain tolerance, and sheen levelClassic, modern, and rustic style preferencesDecision checklist for final parquet specificationLesson 10Look, lines, and colour hold: tannins, air change, stain waysThis part checks how lines, colour, and natural bits like tannins change parquet look over time. You learn to guess air change, stain risks, and colour hold under light and daily use.
