Atlas Gemini RS Silicone Render — 25 kg, 400 Colours
Atlas Gemini RS is a professional silicone thin‑coat finish designed for durable, breathable render performance and flexible exterior protection. Moreover, it is particularly recommended for facades exposed to mechanical impacts (near playgrounds, gates, parking areas) and soiling (dusty or industrial settings). Therefore, Gemini RS suits both refurbishments and new builds, externally and indoors, delivering a highly aesthetic, long‑lasting surface.
Where it works best
Use Atlas Gemini RS in complete ETICS/EWI build‑ups with EPS insulation and on even, properly prepared mineral substrates such as concrete and cement/cement‑lime base coats. In addition, it is an excellent choice for high‑exposure elevations, plinth‑adjacent zones, entrances and circulation routes requiring impact resistance and easy maintenance.
Key technologies
- 4K application & texturing — very good adhesion to tools and walls reduces consumption; faster texturing without repeated trowel cleaning; full coverage with even aggregate distribution for a consistent, attractive facade surface.
- Atlas 3D‑Flex — high elasticity compensates thermal movements between seasons or during rapid weather swings (for example sudden rain on sun‑heated walls), helping to minimise micro‑cracking.
- Mirror Effect — high light reflectance lowers surface temperature, limiting thermal deformation; enhanced UV protection for resins/pigments; photocatalytic self‑cleaning initiates during exposure, extending service life.
- BIOSEC technology — controlled, long‑term release of biocidal protection; elevated concentration persists even during heavy rainfall to inhibit algae and mould.
- CLEAN hydrophobisation — high silicone resin content plus siloxanes create a durable, complex hydrophobic effect in the coating and on the surface. Consequently, rainwater and dust cannot penetrate; water quickly runs off and flushes loose dirt, keeping the facade clean for longer.
System integration (primers, mesh, basecoats)
For a reliable finish, pair Gemini RS with compatible system components. Specifically, prime with a quartz contact such as Ceresit CT16 Quartz Primer or Atlas Cerplast to even absorption and improve adhesion. Moreover, embed fibreglass mesh in a cementitious basecoat from Adhesives & Basecoats to achieve a flat, impact‑resistant substrate before finishing.
Colours, textures and finish
Choose from 400+ tinted colours with consistent, UV‑stable pigmentation for long‑term aesthetics. In addition, the thin‑coat texture supports crisp edges and uniform coverage across large elevations. For colour planning and sampling, consult the Render Colour Charts prior to ordering.
Applications & compatibility
Atlas Gemini RS is suitable for decorative and protective thin‑coat finishing on existing and new buildings, as well as interior accent walls subject to wear. Furthermore, it is compatible with ETICS using EPS boards and with sound, mineral substrates prepared to manufacturer guidance. For coastal or high‑exposure sites, this silicone finish provides hydrophobic, flexible protection and simplified cleaning.
How to apply (overview)
- Check substrate flatness, soundness and dryness; repair and level as required.
- Prime uniformly with CT16 Quartz Primer or Atlas Cerplast and allow to dry per TDS.
- Apply Atlas Gemini RS evenly as a thin‑coat layer using stainless tools; texture consistently, working wet‑on‑wet.
- Protect fresh work from rain, direct sun and strong wind during initial curing; avoid rapid temperature swings.

FAQ
Is Atlas Gemini RS suitable for high‑traffic or polluted areas?
Yes. The CLEAN hydrophobic system and BIOSEC protection help keep surfaces clean and resistant to biological growth, while the robust texture tolerates incidental contact.
Which primer should I use beneath this silicone finish?
Use a quartz contact such as Ceresit CT16 or Atlas Cerplast to equalise absorption and support an even texture.
Does it integrate with EWI?
Yes. Apply over a reinforced basecoat (mesh embedded) in approved Adhesives & Basecoats systems, then finish with Gemini RS.
How do I select colour and grain?
Plan colours using the Render Colour Charts. Choose a thin‑coat texture that matches existing details and site exposure; follow TDS guidance.
What maintenance is required?
Routine low‑pressure rinsing and gentle cleaning are usually sufficient. The hydrophobic, self‑cleaning surface helps facades stay cleaner for longer.
