Madewell's Crack-Bridging Laminate Lining Systems are designed to resist cracks within the substrate up to 1/16" in width and prevent corrosion of reinforcing steel in zoo and aquarium structures. This system performs well in above-ground aquaria where there is occupied space around or beneath the aquarium structures and where the consequences of leaks may be catastrophic. Typically this system will range from .126” (126 mils) to .191” (191 mils) depending on the number of layers of glass reinforcement applied and the amount of Madewell 806 Sprayable Flexible Underlayment or Madewell 1312P Sprayable or Trowelable Epoxy Surfacer & Void Filler used.

Madewell epoxy laminate lining systems may be installed in conjunction with Mainstay ML-72 or Mainstay ML-72F Sprayable Microsilica Mortar in cases where surfaces have been roughened by aggressive surface preparation. This system works well in subterranean structures or structures subject to high water tables and hydrostatic pressures. Mainstay ML-72 Microsilica Mortar is typically applied at a thickness of 1/2” to 2” depending on substrate roughness. Mainstay ML-72F is typically applied at a thickness of 1/8" to 1/2" depending on substrate roughness.

Benefits of Madewell's Crack-Bridging Laminate Lining Systems:

  • PREVENT LEAKS and resist cracks up to 1/16"

  • prevent corrosion of reinforcing steel

  • provide an attractive, durable finish

  • resist physical abuse

Madewell Crack-Bridging Laminate Lining System

Aquarium and zoo crack-bridging laminate system layers

  1. Madewell 1450 Aliphatic Polyurethane Coating, Madewell 1550 Fluorinated Polyurethane Coating, or both, depending on the application.*

  2. Madewell 1312S 100% Solids Epoxy Coating
  3. Madewell 1312E EpoxySaturant with fiberglass reinforced laminate - one layer of 1.5 ounces per square foot chopped glass mat and one layer of 9 ounces per square yard woven glass cloth saturated with Madewell 1312E Epoxy Saturant
  4. Madewell 806 Sprayable Flexible Underlayment for bridging cracks up to  1/16" in width or Madewell 1312P Sprayable Epoxy Surfacer for bridging hairline cracks, depending on the application. NOTE: Madewell 806 Trowelable Flexible Underlayment would be used in cases where a thick cross-section of flexible material is required (e.g. coving a wall/floor joint). Madewell 1312P Trowelable Epoxy Surfacer may be used for rougher concrete applications where a thick coat of material is needed to smooth the substrate.

  5. Madewell 927 Penetrating Epoxy Primer & Sealer

  6. Mainstay ML-72 Sprayable Microsilica Restoration Mortar at 1/2" to 2" thick or Mainstay ML-72F Sprayable Microsilica Mortar at 1/8" to 1/2" thick, depending on the application. NOTE: Mainstay ML-72 or ML-72F in combination with Madewell 1114 Water Based Primer/Admixture may be used if polymer modification is necessary or desired.

*Color stability and gloss of Madewell 1450 would be extended by the use of a clear coat of 1550 or in cases where chlorine is used for disinfection. Pigmented versions of Madewell 1550 do not perform well when exposed to both chlorine and strong ultraviolet light. For service conditions where both chlorine and strong ultraviolet light are present, a clear (unpigmented) coat of Madewell 1550 provides optimal performance.
