Bostik Thinset Calculator
Calibrated to official Bostik Technical Data Sheets. Calculates Bostik BAM (Graphene Infused), Big Tile & Stone, and BVO with GoldPlus system warranty compliance.
Select Bostik Product & Area
Bostik BAM's graphene reinforcement creates a nano-crystalline network that eliminates shrinkage and provides industry-leading shear bond strength (> 550 PSI).
Coverage estimates are planning figures calculated under TCNA standards and ANSI specifications. Actual mortar consumption may vary based on substrate flatness, troweling technique, tile back profile, and jobsite environment.

Bostik Graphene Nano-Platelet Simulator
See how microscopic graphene flakes prevent shear fractures under extreme commercial rolling loads.
Two-dimensional carbon graphene nano-platelets intertwine with calcium silicate hydrate crystals. Under heavy commercial forklift or scissor lift traffic, the graphene network absorbs tensile stress without cracking.

Bostik Mortar Quality Checklist
Ensure complete TDS compliance with Bostik technical standards.
Common Field Bostik Installations
300 sq ft (Bostik BAM)
Requires 9 bags of Bostik BAM Graphene. Withstands continuous commercial automobile and forklift rolling loads.
220 sq ft (Big Tile & Stone)
Requires 7 bags of Big Tile & Stone. Medium-bed non-slump formula prevents lippage on 12×24 tiles.
60 sq ft Over GoldPlus
Requires 2 bags of Bostik BAM over cured GoldPlus liquid waterproofing membrane.
5 Fatal Bostik Product Installation Mistakes
Forensic breakdown of improper Bostik mixing and application errors.
Bostik BAM's graphene nano-platelets and redispersible polymers require 10 minutes of quiet hydration. Skipping slaking prevents the nano-matrix from dispersing, cutting bond strength by 40%.
Bostik BVO is a standard thinset (max 1/4\" bed). Heavy 24×24 slabs sink into the bed overnight, creating hazardous lippage. Always specify Bostik Big Tile & Stone or BAM for large tiles.
Bostik GoldPlus applies as an off-white liquid and cures to a deep translucent gold. Applying mortar before it turns completely gold seals wet liquid under the tile, destroying the waterproofing seal.
Pouring water into stiffening mortar dilutes the Portland cement paste and disrupts ongoing polymer chain cross-linking. Remix dry to break false-set; never add water.

Graphene nano-reinforcement, medium-bed rheology, and GoldPlus system warranties.
1. Graphene Nanotechnology in Thinset Mortar
Bostik BAM represents a breakthrough in cementitious materials science through the incorporation of microscopic two-dimensional carbon graphene nano-platelets. Graphene has a tensile strength 200 times greater than steel. In thinset mortar, the nano-platelets interlock with forming calcium silicate hydrate (C-S-H) crystals, dramatically increasing shear bond strength to over 550 PSI and mitigating micro-fractures under heavy vehicle point loads.
2. Big Tile & Stone Medium-Bed Performance
Bostik Big Tile & Stone is classified under ANSI A118.4HT ('H' for Heavy Tile, 'T' for Thixotropic). Formulated with synthetic rheology control agents, it can be applied up to 3/4" (19 mm) thick without slumping under a 25-pound porcelain or natural stone slab, completely eliminating edge lippage.
3. Bostik Pro-Spec System Warranty Protocol
When an installation utilizes an unbroken chain of Bostik products—SL-150 / SL-175 self-leveling underlayment + GoldPlus waterproofing membrane + Bostik BAM or Big Tile & Stone mortar + TruColor or Hydroment Vivid grout—the project qualifies for Bostik's comprehensive Lifetime System Warranty covering materials and replacement labor.
