Stuc­co­MaxTM is a min­er­al-based exte­ri­or stuc­co that pro­vides sig­nif­i­cant­ly high­er water, impact and abra­sion resis­tance than tra­di­tion­al or syn­thet­ic stuc­co sys­tems. Stuc­co­Max installs quick­ly over most wall sub­strates with­out the need for met­al lath. Stuc­co­Max is well suit­ed for appli­ca­tion over the Bau­tex Wall Sys­tem, mak­ing instal­la­tion fast and increas­ing the long-term per­for­mance of the build­ing.

High impact and abrasion resistance At 3,500 PSI compressive strength, StuccoMax is significantly more durable than conventional three-part stucco and modern EIFS stucco systems.
Non-combustible Does not burn and provides an additional layer of protection to the walls of any building.
Low shrinkage Mineral-based cement does not shrink during curing unlike Portland cement, reducing chances for cracking of the finish.
High water resistance Does not absorb water like traditional stucco systems, further protecting walls from water damage.
High sulphate resistance Not vulnerable to degradation caused by exposure to water with higher concentrations of sulfates.
High freeze-thaw resistance More resilient to freezing temperatures which can damage other finish systems.
Stucco Max-Layers


Initial Pass
An initial base coat of material is troweled and spread evenly onto the wall.
Fiberglass Mesh
An 11-ounce fiberglass mesh is worked into the base layer using a trowel.
Final Pass
A final coat is troweled onto the wall while the material is still wet and then worked to final finish.

Stuc­co­Max can be installed direct­ly over the Bau­tex AMB 20 line of air and mois­ture bar­ri­ers. Stuc­co­Max fin­ish options include (1) hard trow­eled to a smooth flat fin­ish, (2) worked with a sponge trow­el to reveal fine aggre­gate for a tex­tured fin­ish, or (3) worked with a tex­tured roller or sten­cil to cre­ate an orna­men­tal fin­ish.

Suitable Substrates

  • Bau­tex Block and Air & Mois­ture Bar­ri­er
  • Foam insu­la­tion
  • Con­crete Mason­ry Units (CMU)
  • Con­crete
  • Stuc­co

Application Rates

Stuc­co­Max can be applied at dif­fer­ent thick­ness­es, but is typ­i­cal­ly installed in a sin­gle coat from 18″ to 316″ final thick­ness. Fol­low­ing are typ­i­cal yields for a 75 pound bag of Stuc­co­Max mate­r­i­al:

Coverage for 75 pound bag 55 sf 45 sf
Weight (lbs/sq.ft) 1.13 lbs/sf 1.67 lbs/sf

*Prod­uct yields may also vary due to water con­tent and sub­strate con­di­tions.

Finish Options

Concrete Sealer
Stuc­co­Max can be left a nat­ur­al tan col­or by sim­ply apply­ing a con­crete seal­er after the wall fin­ish has cured.

In cas­es where a sol­id col­or is desired, Stuc­co­Max can be paint­ed.

Concrete Stain
Stuc­co­Max will accept con­crete stains, but the result­ing col­or pro­file will tend to be more mut­ed and mot­tled than a paint­ed wall.



Exterior Wall Coating System

Stuc­co­Max is man­u­fac­tured from all nat­ur­al ele­ments, con­tains no Port­land cement or sil­i­ca, and does not emit any pol­lu­tants. This exte­ri­or wall coat­ing sys­tem pro­vides a durable and attrac­tive fin­ish to any build­ing.

* Stuc­co­Max is man­u­fac­tured by and is a trade­mark of GigaCrete, Inc.
