Ronafix Prepacked Render and Screed – Mortar for weatherproof renders

Ronafix Prepacked Render and Screed – Mortar for weatherproof renders. Ronafix Pre-packed Render / Screed is a pre-packed mortar supplied complete with dry powders and a bottle of polymer gauging liquid. Ronafix Pre-packed Render / Screed will provide a weatherproof mortar. Both are bonded with Ronacrete Standard Primer.


Applying the product:

As soon as the material is mixed it must be applied to the wet/tacky primer, using conventional plastering techniques, ensuring total contact with the substrate and ensuring the render does not slump or slide away from the surface. If applying two or more coats of Ronafix Pre-packed Render / Screed, each intermediate layer must be combed to provide a key for the next layer. The following layer should be applied, having first applied Ronacrete Standard Primer, after the previous layer has firmed up sufficiently to support its weight without slumping or pulling away. Keying and priming between layers is necessary to ensure total adhesion through the render.


As soon as possible after finishing the surface cure the surface with Ronacrete Curing Membrane. Alternatively use tight fitting polythene to prevent rapid moisture loss and surface cracking and crazing.

Working Temperatures

Ronafix Pre-packed Render / Screed may be used in most weather conditions and in a wide temperature range, typically from +3°C to 25°C and above. Note that at high ambient temperatures the working time of the mix will be reduced; it will be increased at lower temperatures. Ideally materials should be between 10oC and 20oC before use.
