DESCRIPTION
Stonebond is a grey or white powder composed of cement, sands of selected granulometry, synthetic resins and special admixtures according to a formula developed in our company. Tilebond mixed with water, becomes an easily workable mortar, that can be applied even vertically without slumping and without letting the tiles slip. Stonebond after curing is hardens without appreciable shrinkage attaining a good resistance, adhering perfectly to all materials normally used in the building

APPLICATION PROCEDURE
Preparing the substrate
The substrates must be cured, mechanically strong, free of loose particles, grease, oil, paint, wax and sufficiently dry. Cement substrates must not be subject to shrinkage after tile installation. In mild weather, renders must have cured at least one week for each centimetre of thickness and cementitious screeds must have cured at least 28 days. Cool down with water surfaces that could become too hot due to exposure to sun light.
Preparing the mix
Stonebond mixed with clean water to obtain an homogenous paste free of lumps; after some minutes of resting, it must be re-mixed and the paste is then ready for use. The ratio of water to be used is 23-25 parts per 100 parts (by weight) equal to 5-6 litres of water for 25 kg of Tilebond
Applying the mix
Stonebond is applied with a notched trowel onto the substrate. Choose a trowel that will give a coverage to the back of the tiles of at least 65-70% for walls or for internal light foot traffic. For heavy traffic and for external application, the coverage must be 100%. To obtain good adhesion to the substrate the following system is recommended: first apply a thin coat of Stonebond using the smooth side of the trowel and immediately afterwards apply the desired thickness of Stonebond using the toothed side of the trowel.
