Improvement of the bonding properties of Ottoseal S70, S80, S117, S130 and S140 silicones for natural stone on marble and other natural stone, synthetic stone and cementitious stone. Improvement of bonding properties on some plastics (e.g. PVC) and finishes containing solvents. The surfaces to be grouted or bonded must be perfectly clean, dry and free of dust, grease, oil and old paint. Cleaning non-porous surfaces: clean with OTTO Cleaner T (drying time about 1 minute) and a dry fiber-free cloth. Cleaning porous surfaces: clean the surfaces mechanically, e..g with a steel brush or a smoothing disc to remove loose particles. Apply the primer with a clean cloth/felt pad or suitable paper towel; do not apply with a brush. Apply evenly and thinly; the excess material forms a film that could compromise bonding. Apply the primer very carefully and avoid wetting the natural stone surface next to the sides of the joint to prevent the formation of stains. Smooth substrates do not require long drying times. For structured or absorbent surfaces, allow for at least 15 minutes drying time. The waiting time between the application of the primer and the subsequent grouting can add up to several hours; avoid dust deposits. given the large number of factors which influence the treatment and the application of the product, the user should always perform a test treatment and application. • Spread the product at temperatures between 40°F and 95°F • In warm climates, keep the packaged product in a cool and dry place away from the sun before use • The primer has been created for adhesives and grouts to guarantee excellent adhesion in combination with the latter • Do not use the primer and cleanprimer beyond the joint edges and the bonding surfaces to avoid making them dirty or changing the appearance • For other groups of products, substrates or coverings which have not yet been mentioned, we suggest performing preliminary tests • The interaction and compatibility with the adhesives and grouts has been tested and approved by our technical Ready to use Primer to improve bonding on natural stone, metal and some plastic materials Suitable for interior and exterior floor and wall applications, even in severe operating conditions Des not require drying on smooth, non-absorbent surfaces Free from toluene Elastic grouts
