SUMNER offers a selection of premium irregular limestones. These finishes are suited to top-end projects and discerning customers. Stonework can be fitted tightly so that their are minimal joints, or spaced out for mortared joints.

'L' shaped corner pieces are available for columns, chimneys and return walls. This ensures the stonework looks solid even though it is only 35-50mm thick. We hope you are inspired by these finishes and choose to use one of them on your project.

In 2014 SUMNER® became New Zealand's first and only CODEMARK certified supplier of stone veneer wall cladding. As industry pioneers, we were proud to have attained such a high level of compliance certification. However, over the next seven years CODEMARK proved overly restrictive. It prevented SUMNER® from adhering brick slip and porcelain tiles. It also prevented us from selling SUMNER® board and adhesives to projects not managed by us. So in 2021 we decided to change.

We retired CODEMARK in favour of a simple Product Technical Statement (PTS). Suddenly we could supply our board and adhesives to building merchants. Our range of products increased with the arrival of exciting recycled bricks, not previously posibile under CODEMARK. Moving to a PTS has enabled SUMNER® to better support the adhered masonry veneer industry and at the same time offer greater selection to New Zealander's.

Adhered masonry veneer remains a specialized industry. Our clients choose SUMNER® because they know it works and that it will look great for years to come. Why not let a SUMNER® professional help with your project.
