Materials, calculations and practical guidance for floor renovation.
Calculators
Baseboard Calculator
Calculates baseboard length from a room perimeter, subtracts door openings and rounds up the number of pieces.
Floor area calculator
Adds up to three rectangular sections and shows the area of each section separately.
Insulation calculator
Estimates insulation volume, board count and packs for walls, floors or ceilings, including multiple layers where needed.
Laminate flooring calculator
Turns floor area into the number of laminate flooring packs and shows the allowance separately.
Lumber Calculator
Calculates the volume of one board, total lumber volume and board quantity by count or required coverage area.
Floor screed calculator
Turns room dimensions and screed thickness into a geometric volume without inventing a density for the mix.
Self-leveling compound calculator
Converts floor area and average layer thickness into layer volume and an estimated dry-mix weight.
Tile quantity calculator
Calculates the number of whole tiles from the surface area, tile size and cutting allowance.
Guides
Why Laminate Flooring Creaks
Creaking usually means that planks or locking joints are moving under load. Locate the sound and inspect the subfloor, underlayment and perimeter before trying a quick fix.
Why Laminate Flooring Needs Expansion Gaps
A floating laminate floor needs room for small dimensional changes. Leave the perimeter and other fixed details according to the flooring manufacturer’s guidance.
Why Laminate Flooring Joints Separate
Separating joints mean that the locking system is being moved or was not assembled correctly. Check the planks, subfloor, perimeter and moisture before forcing a repair.
Moisture-Resistant vs Water-Resistant Laminate Flooring
Moisture resistance may mean better tolerance of short spills, while water resistance depends on the specific construction and exposure limits. Neither label means unlimited waterproofing.
Can You Lay Laminate on Fresh Floor Screed?
Do not lay laminate just because fresh screed can be walked on. Moisture, strength, flatness and the flooring manufacturer’s requirements must be checked together.
Can You Lay Laminate on an Uneven Floor?
Laminate flooring does not correct a visibly uneven or flexible subfloor. Movement transfers into the locking joints, causing noise, gaps and early damage.
Can Laminate Flooring Be Used With Radiant Floor Heating?
Laminate belongs over radiant heating only when the flooring, underlayment and heating system are approved as a compatible build-up. Operating limits come from the system documentation.
How Much Extra Laminate Flooring Should You Buy?
Laminate waste depends on the layout and the number of cuts, not only on floor area. Plan the rows first, then choose a practical extra allowance.
How to Prepare a Subfloor for Laminate Flooring
A laminate subfloor should be sound, dry, clean and sufficiently flat for the chosen system. Underlayment is part of the system, not a substitute for preparation.
How to Choose Underlayment for Laminate Flooring
Underlayment supports the flooring system, affects sound and thermal behaviour, and may provide a moisture layer where appropriate. It does not level a badly uneven floor.
Why Does Floor Screed Crack?
A crack in screed may be a drying defect or a sign that the substrate and floor system are moving. Check its stability and surroundings before repairing or covering it.
How Long Does Floor Screed Take to Dry?
A screed can be firm enough to walk on while still retaining moisture. Mix, thickness, substrate and room conditions determine when it is ready for the chosen floor covering.
How Much Extra Screed Mix Should You Buy?
Screed reserve should follow measured area, average thickness, floor geometry and product data. Extra bags cannot compensate for an unsuitable thickness or weak base.
How Thick Should Floor Screed Be?
Required screed thickness is a system decision, not a single number. Average thickness helps estimate material, while local high and low points determine the construction method.
Why Tiles Crack: What to Check Before Replacing Them
A cracked tile is not always a defective tile. Movement below the finish, unsupported areas, impact and moisture can all create the same visible symptom.
How Tile Layout Affects Cutting Waste
Waste falls when you plan the visible axis, edge cuts, joint width, openings and pattern before fixing tiles. The goal is a balanced layout, not zero offcuts.
How Much Extra Tile Should You Buy?
The right extra tile allowance depends on the layout, room geometry, cuts and whether you want spare pieces for future repairs. There is no universal percentage.
How to Prepare a Surface for Tiling
A reliable tile installation starts with a sound, clean, sufficiently flat and cured substrate. Primer does not replace removing weak layers or fixing moisture.
Why Laminate Flooring Swells and What to Do
Laminate flooring can swell because of moisture, blocked expansion space, subfloor movement or damaged joints. Remove the cause before replacing boards.
Why Tiles Come Loose and How to Find the Cause
Loose tiles are usually a symptom of a weak or poorly prepared substrate, unsuitable adhesive, incomplete coverage or movement. Find the cause before retiling.
