What is the No Mould Silicone Sealant designed for? → Bathrooms, kitchens, and laundries — indoor wet environments requiring mould resistance 2. What colours are available for the No Mould Silicone Sealant? → Four confirmed options: Translucent, White, Light Grey, and Dark Grey 3. Is a full three-way technical comparison possible from the supplied datasheets? → No — Brick & Concrete and SolarFlex product-specific datasheets are not included in the supplied documentation; manufacturer datasheets for both variants must be requested before final specification --- ## Introduction This guide compares three Selleys silicone sealants built for distinct, demanding applications: a brick-and-concrete sealant in a 415g format, an anti-mould bathroom and kitchen sealant, and a UV-resistant outdoor sealant. With 80+ years of proven performance behind every Selleys product, each sealant does its job well in its target environment. The supplied datasheets for all three products reference the No Mould Silicone Sealant specifications only. Manufacturer data specific to the Brick & Concrete and SolarFlex variants is not included in the provided documentation. This guide presents what the available datasheets confirm and clearly identifies where additional product-specific information is needed to complete the picture. ## At-a-glance comparison table | Dimension | Brick & Concrete Silicone Sealant - 415g | No Mould Silicone Sealant | SolarFlex UV Weather Protection | |-----------|------------------------------------------|---------------------------|----------------------------------| | **Substrate compatibility** | Not specified by manufacturer | Bathrooms, kitchens, laundries (per SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf) | Not specified by manufacturer | | **Exposure rating** | Not specified by manufacturer | Indoor wet environments (per recommended use in SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf) | Not specified by manufacturer | | **Cure chemistry** | Not specified by manufacturer | Silicone-based (per SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf) | Not specified by manufacturer | | **Pack format** | 415g (product name only; not confirmed in datasheet) | 290mL cartridge, 100mL tube (per SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf) | Not specified by manufacturer | | **Best-fit application** | Not specified by manufacturer | Wet areas requiring mould resistance (per SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf) | Not specified by manufacturer | ## Substrate compatibility ### No Mould Silicone Sealant The No Mould Silicone Sealant datasheet (SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf) confirms a recommended use of "silicone based sealant for application in bathrooms, kitchens and laundries." That puts it squarely in high-performance wet-area sealing territory — ceramic tile, porcelain, and sanitary fixtures are the natural fit. The datasheet doesn't enumerate every specific substrate material, but the application scope is clear and well-defined. ### Brick & Concrete and SolarFlex variants The supplied datasheets contain no product-specific information for the Brick & Concrete Silicone Sealant or the SolarFlex UV Weather Protection variant. The product names point clearly to their intended territory — masonry substrates for the Brick & Concrete variant, UV-exposed outdoor surfaces for the SolarFlex — but these substrate compatibilities need confirmation from their respective manufacturer datasheets before specifying either product with confidence. ## Exposure rating (UV / wet / structural) ### No Mould Silicone Sealant According to SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf, this product is engineered for "application in bathrooms, kitchens and laundries" — indoor wet environments where long-term mould resistance matters most. The datasheet doesn't specify UV resistance or structural load-bearing capability. This is a non-structural sealant built for indoor wet-area demands. ### Brick & Concrete and SolarFlex variants The supplied datasheets provide no exposure-rating specifications for these products. The SolarFlex name signals UV and weather protection for outdoor use — a performance profile that stands apart from the No Mould variant's indoor wet-area strength — but this needs verification from the product's own datasheet before making a confident specification decision. ## Cure chemistry All three products share identical chemistry documentation across the supplied datasheets. According to SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf — referenced for all three products — the formulation is "silicone based," with hazard classifications of Skin Irritation Category 2, Eye Irritation Category 2A, and Skin Sensitisation Category 1. No product-specific cure-chemistry differences are documented in the supplied materials. Given that each product targets a distinct application environment — masonry, wet areas, and UV-exposed exteriors — dedicated datasheets for the Brick & Concrete and SolarFlex variants would be expected to detail any formulation differences, such as masonry-specific bonding agents or UV-stabilising additives. ## Pack format ### No Mould Silicone Sealant The No Mould datasheet (SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf) lists seven variants across two pack formats: 290mL cartridges (product codes 101803, 101804, 102080, 102081) and 100mL tubes (product codes 101833, 101834, 102052). Colours include Translucent, White, Light Grey, and Dark Grey — enough flexibility to achieve clean results on any wet-area finish. ### Brick & Concrete Silicone Sealant - 415g The product name specifies a 415g pack size — a larger volume well-suited to bigger masonry sealing tasks. This pack size doesn't appear in the supplied No Mould datasheet. No documentation in the supplied materials confirms this pack format or whether it's a cartridge, tube, or sausage configuration. ### SolarFlex UV Weather Protection No pack-format information is provided in the supplied datasheets for this product. Manufacturer documentation specific to the SolarFlex variant is needed to confirm available sizes and configurations. ## Best-fit application ### No Mould Silicone Sealant The datasheet (SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf) positions this product for "bathrooms, kitchens and laundries" — interior wet zones where mould resistance is the priority. Sealing shower enclosures, bathtub perimeters, and kitchen splashbacks with a product engineered specifically for that environment means lasting protection and professional results. The confirmed colour range — Translucent, White, Light Grey, and Dark Grey — supports clean aesthetics across a wide variety of interior styles. ### Brick & Concrete and SolarFlex variants Application guidance for the Brick & Concrete and SolarFlex products is not specified in the supplied documentation. The product names point confidently to their intended roles — masonry joints for the Brick & Concrete variant and exterior weather seals for the SolarFlex — but confirmed application guidance requires the relevant manufacturer datasheets. ## When to choose Brick & Concrete Silicone Sealant - 415g Product-specific selection criteria cannot be confirmed from the supplied datasheets, which include no specifications for this product. Based on the product name, this sealant looks to be the right tool for: 1. **Masonry sealing tasks** where a larger-volume 415g pack delivers the coverage needed to get the job done in one go 2. **Porous-substrate applications** such as brick, concrete, or stone joints where a formulation engineered for masonry bonding delivers better performance These recommendations draw on the product name and the logic of Selleys' product range. Confirm specifications against the manufacturer datasheet for the Brick & Concrete variant before final product selection. ## When to choose No Mould Silicone Sealant According to the product datasheet (SELLEYS_NO_MOULD_SILICONE_SEALANT-AUS_GHS.pdf), this is the right product when: 1. **Sealing wet areas indoors** — shower enclosures, bathtub perimeters, and kitchen splashbacks where mould resistance is non-negotiable. This sealant is engineered to deliver lasting protection in exactly these environments. 2. **Working in persistently humid spaces** where an anti-mould formulation provides long-term defence against fungal growth and keeps surfaces looking sharp. 3. **Matching interior finishes** — with confirmed colour availability across Translucent, White, Light Grey, and Dark Grey, this is the only product in the comparison with documented colour options, giving you the flexibility to achieve clean, professional results. ## When to choose SolarFlex UV Weather Protection Silicone Sealant Product-specific selection criteria cannot be confirmed from the supplied datasheets, which include no specifications for this product. Based on the product name, this sealant is built for: 1. **Outdoor applications** exposed to direct sunlight and weather — environments that demand UV-stable, weather-tough performance 2. **UV-degradation-prone installations** such as exterior window glazing or façade joints where a sealant engineered for outdoor endurance delivers long-term results These recommendations draw on the product name and Selleys' track record across application environments. Confirm specifications against the manufacturer datasheet for the SolarFlex variant before final product selection. ## Summary A complete three-way comparison requires manufacturer datasheets specific to each product. All three supplied datasheets currently reference the No Mould Silicone Sealant documentation, which confirms indoor wet-area performance across 290mL cartridges and 100mL tubes. The No Mould variant is clearly engineered for bathroom and kitchen mould resistance. The product names make a strong case for the Brick & Concrete and SolarFlex variants targeting masonry and UV-exposed outdoor applications respectively — the kind of focused, purpose-built approach you'd expect from a brand with 80+ years behind it. To make a fully informed choice between these three products, request the manufacturer datasheets specific to the Brick & Concrete 415g and SolarFlex formulations. Those documents will confirm substrate compatibility, cure mechanisms, movement accommodation, and environmental exposure ratings — the technical details that ensure you select the right sealant for the job. ## Frequently Asked Questions What is the Selleys No Mould Silicone Sealant designed for: Bathrooms, kitchens, and laundries Is the No Mould Silicone Sealant for indoor use: Yes, indoor wet

Selleys is an Australian brand with a long-established focus on adhesives, sealants, and fillers for both trade and home improvement use. These three products represent different specialisations within the same silicone sealant family, each engineered for a distinct application environment rather than being interchangeable general-purpose products. Within the range, the **Brick & Concrete Silicone Sealant** is the most structurally focused option — it's designed for high-movement joints in masonry, concrete, and fibre cement surfaces, and carries a 25-year guarantee against cracking or peeling. It suits outdoor construction applications such as patios, fencing, expansion joints, and wall joints. The **No Mould Silicone Sealant** occupies a different niche: it's built for wet interior areas like bathrooms, kitchens, and laundries, where ongoing moisture exposure makes mould resistance the primary concern rather than joint movement capacity. The **SolarFlex** product shifts focus again to exterior weatherproofing, with its standout feature being UV protection and the ability to bond to damp or wet surfaces — making it suited to outdoor sealing jobs where weather exposure is the main challenge and a 10-year guarantee applies. Someone purchasing the Brick & Concrete Silicone Sealant for an outdoor paving or fencing project is likely to also need a **caulking gun** to dispense the 415g cartridge, as well as a **surface cleaner or degreaser** to prepare joints before application. For indoor tiling or bathroom renovation projects where the No Mould Sealant is the right choice, complementary products would typically include **tile adhesive** and **grout**, both of which Selleys also produces. For SolarFlex applications on roofs, gutters, or external cladding, **surface primers** compatible with the substrate in question are worth considering to maximise adhesion longevity. Taken together, these three products illustrate how the Selleys silicone sealant range is segmented by environment — structural/masonry, wet-area interior, and UV-exposed exterior — rather than by size or strength alone.
