Step 1 of 8
What surface are you applying X-Bond to?
Coverage rates vary by substrate — from your tech sheet.
Concrete
60–75 sq ft per kit (2 gal Liquid + 1 bag Stone)
Painted surface
60–75 sq ft per kit
Ceramic tile
55–75 sq ft per kit
Vinyl tile
60–75 sq ft per kit
Natural stone
50–100 sq ft per kit
Metal
60–75 sq ft per kit
Step 2 of 8
Where is this surface?
Affects mix ratio — floors use 1:2½, walls use 1:3 (Liquid:Stone).
Floor / horizontal
1 part Liquid : 2½ parts Stone
Wall / vertical
1 part Liquid : 3 parts Stone
Step 3 of 8
Which X-Bond texture finish?
Smooth
Polished, ultra-refined — requires Microbond top coat before sealing
Natural
Textured, artisanal — sealed directly over X-Bond skim coats
Step 4 of 8
What is the total square footage?
Measure each area (length × width) and add them together.
300sq ft
505,000
Step 5 of 8 — Optional
Do you need SEMCO Liquid Membrane?
Yes — add Liquid Membrane
Waterproofing + crack bridging · 2 coats min · 5-yr warranty (10-yr non-traffic)
Wet areas · Cracks · Below gradeNo — skip Liquid Membrane
Dry interior surfaces in good condition with no cracks or joints
Step 6 of 8
What type of substrate are you waterproofing?
This affects how much Liquid Membrane you'll need per coat.
Open pore substrate
Unfinished concrete, masonry, stone — 25–50 sq ft per gallon
Closed pore substrate
Tile, plywood, cladding — 35–65 sq ft per gallon
Over X-Bond scratch coat
100–150 sq ft per gallon
Step 7 of 8
Which sealer system?
