Merlex Stucco Keeping it Premium since 1963


Introducing the Merlex System for Improved Smooth Stucco

Introducing the Merlex system for improved smooth stucco

We learned from our customers that cracking is the single biggest complaint with smooth-troweled Santa Barbara Finishes.  And we learned how our most skilled craftsmen were reducing cracking by up to 90 percent.  So we designed a new product made specifically to produce great looking Santa Barbara Finish without the same cracking problems.

Introducing Basex polymer-modified base coat.  Applied over brown coat with Merlex 4-ounce mesh embedded, Basex is a crack-resistant surface.  So, when you apply Merlex Santa Barbara Finish on top of Basex, cracking of the finish is reduced by up to 90 percent.  To realize the full benefits of the system, you must follow these steps:

  1. Apply one coat of Basex and immediately embed Merlex 4-ounce mesh in the second coat of Basex.  Let dry 24 hours.
  2. Apply Merlex Superhold EVA bonder by brush, roller, or spray over the Basex.
  3. Apply Merlex Santa Barbara Finish over Basex prepared with Superhold following normal product directions.  Merlex Acrylex acrylic admixture may be used at a rate of 1/3 gallon per 90 pound bag of Santa Barbara Finish to improve crack-resistance and bond.

Basex is available in #20, #30, and #60 grit, and is also suitable to repair existing stucco.  

Basex is specially formulated to reduce cracking in smooth-troweled Santa Barbara Finish.  It consists of the same top-quality sand, cement, and polymers that has made Poly Prep the choice for coating and embedding mesh with architectural foam shapes.  Plus, Basex has a high polymer content for flexibility, fibers for flexural and tensile strength (crack resistance), and proprietary additives for working time and workability.

NOTE:  The Merlex system should not be expected to completely eliminate cracking, and must be used in its entirety (Basex, Superhold and/or Acrylex, and Merlex Santa Barbara Finish).  Major structural forces acting on the plaster assembly may crack through the Merlex system, even if all product directions are followed.
