VASA™ Tile Adhesive Flex HP 230 is suitable for bonding ceramic tiles and large-format slabs to stable mineral substrates such as cement mortar, concrete and brick walls.
| Substrate Type | Recommended Tile Size |
| Stable substrates such as cement mortar, concrete and brick walls | Small – Large tiles |
| Substrates with significant deformation | Small-large tiles |
| Substrate Type | Recommended Tile Size |
| Stable substrates such as cement mortar, concrete and brick walls | Small-large tiles |
| Substrates with significant deformation | Small- medium tiles |
For the installation of large ceramic slabs with a thickness of up to 12 mm, a surface area greater than 1.62 m², or a long edge greater than 1500 mm, additional mechanical fixing brackets may be required, particularly in areas subject to significant movement or deformation.
VASA™ Tile Adhesive Flex HP 230 complies with the requirements of AS ISO 13007 C2TE S1 classification.

Actual consumption may vary depending on substrate flatness, tile size, trowel size and installation method.
Recommended tools include: electric mixer, mixing bucket, measuring cup, notched trowel, flat trowel, rubber mallet, level, tape measure, chalk line or laser level, tile cutter, sponge, tile spacers and other standard tiling tools.
Before installation, inspect the back of the tile and remove any mould release agent, dust or impurities that may affect adhesion.
The substrate must be:
Substrate flatness should not exceed 3 mm over a 2 metre span.
The prepared adhesive should be used within approximately 2 hours.
Apply a thin, firm layer of adhesive onto the substrate using the flat side of the trowel. Then apply an additional layer and comb the adhesive using a suitable notched trowel.
For tiles with large back ribs, uneven backs or tile sizes equal to or greater than 300 × 300 mm, the combined installation method is recommended. This means adhesive should be applied to both the substrate and the back of the tile before placing the tile into position.
During installation:
In hot, windy or highly absorbent conditions, tiles should be installed promptly after the adhesive has been applied.
Clean tools and tile surfaces with water while the adhesive is still fresh. Hardened adhesive must be removed mechanically.
Do not disturb the tiles, allow foot traffic or commence grouting for at least 24 to 48 hours after installation.
| Condition | Minimum Protection Time |
| Light traffic / grouting | 24 to 48 hours |
| General traffic | 72 hours |
| Heavy traffic | 7 days |
| Rain exposure | 72 hours |
| Freezing conditions | 21 days |
| Water immersion | 28 days curing required |
Handle with care during transportation to avoid impact, rain exposure or damage to the packaging.
Store the product in a cool, dry and well-ventilated warehouse. Keep away from moisture, direct sunlight and water contact.
Under correct transport and storage conditions, the product has a shelf life of 12 months from the date of manufacture.
