Coverage, package sizes and field-tested buying tips — so quantities from our calculators translate to the right purchase.
Ceramic Wall Tile
Kiln-fired clay tile for walls and dry-area floors. Glazed face is water-resistant; body still needs waterproofing behind it in wet zones.
Concrete Pre-Mix (Bagged)
Bagged sand-gravel-cement mix; add water. For pads, footings and small slabs where ready-mix trucks aren’t practical.
Crushed Gravel (¾" minus)
Angular crushed stone with fines — compacts into a stable base for patios, driveways and paths.
Fiberglass Batt Insulation
Flexible mineral-fiber insulation for stud bays and attics. R-value depends on thickness and density; compression destroys performance.
Interior Acrylic Latex Paint
Waterborne paint for walls and ceilings: fast-drying, low-odor, soap-and-water cleanup. Sheen tiers (flat → semi-gloss) trade washability against flaw-hiding.
Laminate Flooring (AC3/AC4)
Fiberboard core with photographic wear layer and click-lock edges. Floats over the subfloor; never fastened down.
Pressure-Treated Lumber
Wood preserved for ground contact and outdoor exposure. Structural rating stamped on the board; treatment protects against rot and insects, not water and UV.
