Objective 1.1. BEAL Testing Services were contracted by Original Stone Ltd to verify the adhesive capabilities of the SUMNER Grip adhesive to adhere to the back of large, low porosity MAXIMUM (Italian made) porcelain tile to be used as part of a cladding system with a fibre cement sheet base over battens. The tiles will be supported by stainless steel L brackets in addition to the adhesive. Testing was carried out to assess the flatwise tensile strength of the bond between the SUMNER Grip and the tile after 7 days curing, and again after 20 days thermal and humidity cycling. A third sample was allowed to sit for the same period of time as the thermal and humidity cycling and then submerged in water for 36 hours before testing. 2. Methodology 2.1.

Freeze Thaw (Thermal cycling) Test Procedure: BEAL Test Procedure 108 – Standard Test Procedure for the Freeze Thaw Conditioning Description: This consists of thermal cycling from -15°C to 70°C. A single cycle consists of 3 hours heating to 70°C, 3 hours off, 3 hours cooling to -15°, 3 hours off. A total of 40 cycles were carried out on the aged samples. Humidity is allowed to cycle naturally during the temperature cycles. 3. Criteria 3.1. A criterion was not set for these tests. The results are subject to review by an engineer or other suitably qualified party. 4. Sample Preparation 4.1. A clean piece of tile was adhered to a clean section of fibre cement sheet with the SUMNER Grip adhesive. The surfaces to be adhered were dusted off only, they did not receive any other type of cleaning. The adhesive was prepared in accordance with the supplier’s instructions. It was manually mixed with water in 1kg to 0.16L ratio for 3 minutes, rested for 2 minutes, and mixed for a further 1 minute. The Adhesive was then applied to the back face of the tile within 5 minutes with a smooth edged trowel. A plastic sheet was laid over the adhesive to control the drying rate. After 6 days of curing, the sample was cut into fifteen 50x50 mm pieces. Steel grips were adhered to the 50x50 mm faces with a 2-part epoxy for testing. Sample preparation was carried out on the 12/8/2016.

1. Objective
1.1. BEAL Testing Services were contracted by Original Stone Ltd to verify the adhesive capabilities of the SUMNER Grip adhesive to adhere to the back of large, low porosity MAXIMUM (Italian made) porcelain tile to be used as part of a cladding system with a fibre cement sheet base over battens. The tiles will be supported by stainless steel L brackets in addition to the adhesive. Testing was carried out to assess the flatwise tensile strength of the bond between the SUMNER Grip and the tile after 7 days curing, and again after 20 days thermal and humidity cycling. A third sample was allowed to sit for the same period of time as the thermal and humidity cycling and then submerged in water for 36 hours before testing.
2. Methodology
2.1. Tensile Strength Standard: ASTM C297 – Standard Test Method for Flatwise Tensile Strength of Sandwich Constructions Grip Separation Speed: 4 mm/min
2.2. Freeze Thaw (Thermal cycling) Test Procedure: BEAL Test Procedure 108 – Standard Test Procedure for the Freeze Thaw Conditioning Description: This consists of thermal cycling from -15°C to 70°C. A single cycle consists of 3 hours heating to 70°C, 3 hours off, 3 hours cooling to -15°, 3 hours off. A total of 40 cycles were carried out on the aged samples. Humidity is allowed to cycle naturally during the temperature cycles.
3. Criteria
3.1. A criterion was not set for these tests. The results are subject to review by an engineer or other suitably qualified party.
4. Sample Preparation
4.1. A clean piece of tile was adhered to a clean section of fibre cement sheet with the SUMNER Grip adhesive. The surfaces to be adhered were dusted off only, they did not receive any other type of cleaning. The adhesive was prepared in accordance with the supplier’s instructions. It was manually mixed with water in 1kg to 0.16L ratio for 3 minutes, rested for 2 minutes, and mixed for a further 1 minute. The Adhesive was then applied to the back face of the tile within 5 minutes with a smooth edged trowel. A plastic sheet was laid over the adhesive to control the drying rate. After 6 days of curing, the sample was cut into fifteen 50x50 mm pieces. Steel grips were adhered to the 50x50 mm faces with a 2-part epoxy for testing. Sample preparation was carried out on the 12/8/2016.
