StoRend Systems

StoRend 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 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

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.

Acrylic render finish with aggregate (StoSuperlit)

Silicone resin render finish (StoSilco)

Self-cleaning render with Lotus-Effect® (StoLotusan)

StoRend Cote
