Python PR

Python PR is a highly advanced styrene butadiene polymer designed to prime, stabilise and seal substrates prior to the application of Python tile adhesives and self levelling compounds.

Python PR increases the adhesion and prolongs the working time of tile adhesives and self levelling compounds. Python PR can be used on both absorbent and non-absorbent surfaces, internally and externally.

Surfaces must be sound and free from dust, dirt, grease, oil and any other contaminants. Any laitance or surface treatments must be removed before use. Concrete, sand/cement screeds, anhydrite screeds and power floated concrete must be fully cured and dust removed ideally by vacuum. The temperature of the surface must be above 5°C when the PR is applied. Underfloor heating must be switched off 2 days before application. Timber and over boarded substrates must be rigidly braced and sufficiently constructed to take domestic loading without movement.

Shake well before use. PR should be diluted accordingly for the relevant substrate, see page 3. Apply PR evenly to the whole surface to be treated with a paint roller, brush or sponge. Do not over apply as this can cause the primer to skin over, only a thin coat is required ensuring that you have 100% coverage. Wash tools after use with warm water.

The drying time of PR will depend on the porosity of the substrate and the ambient conditions/temperatures. In ideal conditions, PR will take 30 – 45 minutes to dry. Once primed, avoid trafficking the primed area.

The components of Python PR are not classified as hazardous. However, it is recommended that elementary health precautions be followed, including: wear protective gloves and glasses, ventilate working areas, if there is accidental contact with skin or eyes wash thoroughly with water. Do not allow the paste to dry on the skin. Keep out of reach of children.
