Lanka Bloc White

Description

Usage & Installation

We recommend installing the BLOC SERIES stacked / straight joint: If it is to be installed broken joint there are issues that must be considered and approved by both the installer and the final owner before proceeding with installation.

Bloc may have “cupping” where the tile rises in a slight hill and the center of each piece is higher than the edges. The issue is made more evident on the 4 x 16 size because of the production method. It is made by pre-scoring and cutting the 8 x 16 (leaving one cut edge and three pressed edges on each tile). The pressed edges are softer and more rounded, while the cut edges have less cushion. When a cut edge is placed next to a rounded edge, the cut edge appears to be higher than the pressed edge, even on flatter pieces.

PLEASE NOTE THE FOLLOWING:

• It is not an issue if the material is installed with a straight joint, and this is our recommendation.

• It is not advisable to install the tile in a subway, brick pattern, with alternating rows offset by 50%. A broken joint with an overlap of one-third (1/3) or less is possible, but would still need to be worked out by the installer. Contractors should be made aware of this. Most manufacturers recommend a maximum offset of one-third (1/3) of the length of the tile on all large format tiles when setting a running bond. Please refer to ANSI requirements for setting large format tiles, ANSI A 108.2 Section 4.3.8.

• The issue is more evident in horizontal installations and less visible when the tile is installed vertically. It is exacerbated by down lighting which can even make flat tile look like it has cupping because of the way the shadows fall.

Bloc series is unrectified. When mixing sizes and finishes, it is advisable to do the layout with actual tiles before installation. Shade variation may occur between field sizes and between field and trims due to the shape of trim pieces and nature of trim production.

Bloc is intended for interior walls. If installing with a cement-based adhesive, it is recommended to use a flexible setting material. All substrates should be properly reinforced to be sure there is no movement. Wood studs need to be dry and properly braced with a minimum depth of 3 1/2”. For mortar installations, the mortar bed has to be cured (less than 2% humidity) and has to have proper reinforcing.

Rectified 6 x 24 & 12 x 24

These sizes are rectified, but maintain the small cushion that is characteristic to this series.

Trim

Please also note that if a Pencill Bullnose is needed, the 1/2 x 8 Pencil Bullnose in Lanka Dune (LADU–/PBN18) should work well as coordinating trim.
