Sto Render
StoRend – Synthetic Render Systems
The StoRend range of Sto render systems allow you the flexibility to realise even the most demanding designs.
They can be flat or curved, concave or convex, white or vibrantly coloured.
By specifying Sto thin-coat synthetic renders, you avoid the problems associated with traditional cementitious renders, such as cracking and colour fading.
Sto renders feature greater durability, exceptional flexibility and are through-coloured to reduce maintenance requirements.
StoRend synthetic render systemsStoRend synthetic render systems assist in overcoming many substrate issues to provide an attractive, through-coloured and long lasting render finish.
Sto synthetic renders are available in a wide selection of textures and grain sizes, and in a range of up to 800 colours.
For Masonry, Brickwork & Blockwork
StoRend Sto Render systems for masonry, brickwork and blockwork substrates combine a levelling coat for correcting surface irregularities (up to 20mm) with an attractive synthetic render finish.
StoRend Flex Cote
Our flagship synthetic render system uses only the highest quality materials to provide exceptional crack resistance, weather protection and a durable,
good looking render finish. The cement-free StoArmat Classic reinforcing coat provides up to 15 times more crack resistance than traditional cementitious renders.

Self-cleaning render with Lotus-Effect® (StoLotusan)
For Porous/Smooth Substrates
StoRend systems for substrates with low adhesion use a fibre-reinforced levelling coat to provide a stronger bond with the substrate, and prevent unwanted surface defects such as crazing.
StoRend Fibre Plus
A high quality render system with a fibre-reinforced levelling coat combined with a tough, flexible reinforcing mesh to yield exceptional levels of crack resistance.
1. Substrate
Smooth/porous substrates (e.g. aerated concrete)

Self-cleaning render with Lotus-Effect® (StoLotusan)
StoRend Fibre
A modified, fibre-reinforced levelling system, designed for substrates with low adhesion and little risk of mechanical movement. If there is a risk, the StoRend Fibre Plus system should be used.
1. Substrate
Porous/smooth substrates (e.g. aerated concrete)
2. Levelling Coat
StoLevell Reno fibre-reinforced levelling coat
3. Primer
Sto-Primer intermediate coat for render finishes
4. Render Finish
