All about Python LR
I’m Andy Parkin, Managing Director of the Multi-Award-Winning Speed Screed. Today I’m here to give you a little more insight into Python LR.
What is Python LR?
Python FL is an ultra-swift setting and drying, flexible self-levelling floor compound. It has been uniquely formulated using advanced binder technology and selected additives for a fast-track solution.
Python LR has exceptional flow and adhesion properties, making it sufficient for commercial and domestic applications. It is suitable for use over a broad range of substrates along with sand/cement screeds, concrete, flooring grade asphalt/bitumen, ceramic, porcelain and terrazzo tiles, epoxy damp proof membranes and plywood.
The uses of Python LR
Python LR is also excellent for encapsulating electric underfloor heating elements and for usage over underfloor heated screeds.
Python LR is quick setting, meaning ceramic tiles can be equipped after as little as 3 hours, and fancy floor coverings can be installed after 24 hours.
Under certain conditions, Python LR is good for use externally.

Always mix by adding the powder to water. Python LR is blended with a water content of 4.5 – 5.0 litres of water per 20kg of Python LR. In a neat mixing vessel, add the pre-measured water before slowly adding the powder component, blending with an electric paddle until a smooth and lump-free consistency is achieved. Once mixed, allow the product to stand for 2 minutes and stir again prior to application. Do not add water once mixed. More than 5.0 litres of water per 20kg will result in water bleed and then extended drying times and a weakened mix.
N.B. Once mixed, Python LR will remain doable in the bucket for 20 – 30 minutes at 20°C.
Pour a small quantity onto the prepared surface and trowel down lightly to a depth between 2mm and 50mm. The use of a spiked roller is recommended directly in thin applications in order to remove entrapped air and smooth outflow lines. Setting time will depend on atmospheric temperatures, it will be slowed by lower temperatures and accelerated by higher temperatures. If a depth greater than 50mm is required, allow the first application to dry and prime the surface with Python PR at a 3:1 ratio before putting a subsequent coat. Clean tools right after use with clean water. Python LR is ideal for pump application. Mix in accordance with the pump manufacturer’s direction and ensure that regular flow checks are carried out. Ensure the water content is precise and that there is no surface separation.
So, there you have it, a summary on Python LR.
