Adhered Masonry Veneers including schist cladding, stone veneer, and brick cladding.

Many brick, stone and tile cladding options are available to consumers these days. The installation process can be as simple as gluing the decorative masonry to a wall. Wall tiles can be as thin as 4mm, bricks 11 to 25mm and stone approximately 20 to 60mm. The advantages of adhered masonry is it costs less than foot-loaded masonry, there is lower earthquake risk, and with our SUMNER® Adhered Masonry Veneer system it is easier to gain council consent. These three reasons have contributed to why adhered masonry veneers are so popular.

SUMNER Schist Cladding System

SUMNER® is the best system on the market for adhered masonry veneer.

For more than 15 years, our system has lined homes throughout New Zealand. During this time, more and more builders have turned to SUMNER®. Mainly for its reliability and the knowledge that our system protects their clients and projects from cladding failures. Customers looking for cost savings should select a less expensive stone rather than an inferior system.

SUMNER® also supplies the masonry finishes. Delivered ready to install, along with the adhesive, board, tape and components to complete your project successfully. You can see a photo of our SUMNER® System (left). We designed and tested every element to ensure installations are weathertight, structural and problem-free. We do not endorse product substitution, which may result in problems and failures. Our product technical statement ensures performance. To protect our clients and the industry, we always inform building control officers any system or product substitutions.

  1. Avoid Direct Fix - For years the tile industry direct fixed over membraned decks. The method had expensive weather tighness and repair issues, however, where councils were liable. Unsurprisingly this method was removed from the NZBC. Now cladding is following suit. Councils are rejecting consent applications where they would be responsible for direct fix cladding failures. This makes SUMNER's cavity over masonry an excellent solution to direct fix.
  2. Avoid unwarrantable precladdings. We recommend our SUMNER Board but not Hardies, BGC or Eterpan.
  3. We are dedicated to the commercial supply of adhered masonry veneers.
  4. Product Technical Statement for quality products needed for sucessful long lasting installations.
  5. SUMNER Board is denser than most fibre-cement boards, having a density of 1420 kg per cubic metre. The stone, adhesive and board are similar in their makeup and consequently have a similar linear coefficient of expansion and contraction -an advantage of using a system designed specifically for stone veneer.


SUMNER® Schist Veneer Applications

As you can see in our project gallery, SUMNER® adhered masonry is used on commercial and residential projects throughout New Zealand. Many installations include columns or chimneys which require external corners. To discuss this further we have an example of stone veneer columns which came up fantastic.


Stone Columns when using panels

There are two methods for cladding columns when using modular panels. In both instances, the structure needs to be built to the correct size as panels are in predefined modular lengths. Our instant quote lets you select either option and alerts you about the price difference to help you with your decision.


Solid L Corners

Solid L Corner units are preformed to wrap around the column. They are available in our Otago Series, Ledgestone Series, Traditional Series and some Bluestone Series products. This unit is slightly more expensive but well worth the cost.


Natural Ends

The following method uses Natural End panels to tile around columns. Install the first course in a clockwise direction. Adhere the first panel, so the natural end extends past the column's edge. Then continue clockwise by fitting the sawn end of the panel in behind the overhang of the first. Repeat until all four sides of the column have their first course of stone. We use the same methodology for subsequent courses but alternate the direction of orientation each time. The finished column will look similar using Solid L Corners but costs less.


Adhered masonry can create breathtaking features, such as the large stone chimneys of bespoke mansions or the entrance pillars to prestigious subdivisions whose initials monogram the stonewalls. Adhered masonry is in the entrance foyers of grand hotels and wraps around the warm interior stone fireplaces of family homes. Sturdy bluestone is a popular masonry veneer for boundary walls. Recently, we have even been using recycled red brick slip to recreate New York styled apartments' walls. The value of adhered masonry is in its appearance. However, if installed incorrectly, without using the correct products or method, then it can come unstuck. We highly recommend using SUMNER® adhesive products. Also, if you think your project will benefit from formal installation training, please contact us. The following photos are from some of our training days:
