Project Profile – Beauty on the Beachside

Posted in Mer-Ko Decking Solutions  |  April 25, 2024

In Redondo Beach, California, a lovely beachside condominium community, Casa Bahia, overlooks a stunning ocean view. Throughout its 40+ years standing, the building underwent several maintenance upkeeps and repairs, especially regarding protection against the misty ocean breeze. 


Addressing the Issue/Challenges 

The building’s 4000 square foot courtyard deck required waterproofing resurfacing. Westcoat rep Bill England worked with Craig Schlumbohm of Pacific Construction Analysts to find the perfect solution. Originally, the project specified Westcoat’s MACoat system; however, after removal of the entire deck system, applicators WICR Riverside discovered concrete precast panels with wood-filled large expansion joints. Bill initially recommended full removal of the concrete panels and a split tab waterproofing system be installed to better suit the unusual substrate. However, considering budget constraints, the HOA, Pacific Construction Analysts, and WICR needed a more cost-effective solution.  


The Solution – Mer-Ko® Weather Deck 

Mer-Ko’s Weather Deck emerged the next best option. Not only was it a financially viable choice, but its ability to also “float” over the substrate presented a seamless solution. Prior to Weather Deck installation, new door pans, deck to wall flashing, and significant sloping with MK-10 Underlayment Cement were required. Once these preparatory measures were in place, WICR Riverside was able to proceed with the system application.  


Residents of Casa Bahia can now walk with confidence knowing that their safety is ensured and recognized as a priority.

Shur Deck – The Affordable Housing Solution

Posted in Mer-Ko Decking Solutions  |  May 26, 2020

Exterior of affordable housing

The need for space-saving, affordable housing complexes is not diminishing anytime in the near future. In fact, low income, and multi-family apartment complexes are rapidly outnumbering single-family, new construction homes in the United States – a trend that doesn’t seem to be slowing. Part of protecting these huge new investments include going the extra mile to ensure your new endeavor performs to the best of its ability.

Protecting balconies, walkways, decks, rooftops, and stairways from destructive elements can greatly increase the lifespan of your substrate and can save time and money on future damage and potential repairs. Because affordable housing complexes are constructed with a budget in mind, it is important you can attain both quality and cost-effectiveness when choosing waterproofing solutions.

Shur Deck – The Affordable Housing Solution

The Shur Deck Waterproofing System is a multi-layer, cementitious system designed for use over plywood or concrete substrates. This system consists of reinforcing metal lath (when installed over plywood), cementitious filler, and a reinforced flexible latex waterproofing membrane. This waterproofing membrane incorporates an anti-microbial component that inhibits the growth of mold and mildew on the membrane surface and in damp settings – perfect for coastal or rainy environments.

An acrylic, matte topcoat available in 9 opaque colors, finishes the system leaving it protected from harmful UV rays and is chemical resistant. The durable surface allows for regular daily maintenance and won’t degrade with scrubbing or cleaning solutions.

Some great advantages to the system:

• Cost-Effective
• Seamless & monolithic
• Excellent adhesion to plywood substrates
• Will not soften under high temperatures
• Resists degradation from UV, ozone, and weathering
• Outstanding long-term durability and performance
• Solvent-free / Environmentally friendly
• One Cement System

The Shur Deck System has some important ratings and reports, too!

• One-Hour Fire Resistance Rating
• Class A Fire-Retardant Roofing System
• IAPMO Evaluation Report # 517

The Shur Deck system is not only top of the line for waterproofing and protection but also looks great. Aside from standard trowel finish, the system can also be textured by using design options such as skip trowel texturing, trowel knock-down, stippling, and stenciling. This wide array of finish options provides unlimited aesthetic design.

The system comes standard with a 5-year warranty, with longer warranties also available. Shur Deck Underlayment is additionally available for use under laminate or tile. Versatile and powerful, the Shur Deck system is a great asset to your investment and is a perfect way to add appeal to your affordable housing properties.
