Plas­ter­MaxTM is an extreme­ly hard min­er­al-based inte­ri­or plas­ter that is high­ly resis­tant to impact, abra­sion and oth­er abus­es and pro­vides out­stand­ing abuse resis­tance for high traf­fic and use build­ing spaces. This abuse-resis­tant inte­ri­or wall fin­ish is an ide­al fin­ish for many com­mer­cial and insti­tu­tion­al build­ings includ­ing edu­ca­tion, retail, med­ical, hos­pi­tal­i­ty, pub­lic safe­ty, cor­rec­tion­al facil­i­ties, and mul­ti-fam­i­ly hous­ing.

High impact and abrasion resistance At an incredible 8,500 PSI compressive strength, PlasterMax is one of the most durable interior wall finishes available today.
Non-combustible Does not burn and provides an additional layer of protection form fires and flame spread indoors. Meets NFPA 101 Life Safety Code.
Low shrinkage Mineral-based cement does not shrink during curing unlike Portland cement, reducing chances for cracking of the finish.
Low VOC Natural ingredients and low in volatile organic compounds for quality indoor environments.


Initial Pass
An initial base coat of material is troweled and spread evenly onto the wall.
Feiberglass 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.

Plas­ter­Max 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
  • Gyp­sum or cement wall board
  • Fiber or mag­ne­sium-oxide wall board
  • Con­crete Mason­ry Units (CMU)
  • Con­crete

Application Rates

Stuc­co­Max can be applied at dif­fer­ent thick­ness­es, but is typ­i­cal­ly installed at 316″ final thick­ness for Lev­el III (high­est) abuse resis­tance. Fol­low­ing are typ­i­cal yields for a 75 pound bag of Plas­ter­Max mate­r­i­al:

Coverage for 75 pound bag 40 sf
Weight per square foot 1.78 lbs

*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.



Interior Wall Coating System

Plas­ter­Max is man­u­fac­tured from all nat­ur­al ele­ments, con­tains no Port­land cement or sil­i­ca, and exceeds USEPA and Cal­i­for­nia indoor air qual­i­ty and VOC stan­dards. This inte­ri­or wall coat­ing sys­tem pro­vides a durable and attrac­tive fin­ish to any build­ing.

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