Be Bold.
Investing in a new kitchen, bathroom, or upgrading your windows and doors involves a substantial commitment of both time and money for your home. Take your project from ordinary to extraordinary with a seamless finish.
Go wild with colour with no compromises.
Coloured silicone is the ultimate finishing touch for perfect results. Fix unsightly, draughty gaps with the perfect colour-match. Rainbow Coloured Silicone Sealants are designed for both indoor and outdoor applications and will bond to many different surfaces including window frames, metal, plastic, brick, and wood. Formulated with anti-mould properties, these sealants are particularly well-suited for high-humidity sanitary areas including kitchens and bathrooms.
Typical Applications:
Rainbow Coloured Silicone Sealants serve as a robust frame sealant,
catering to a diverse range of building and construction joints. These
sealants are ideal for various applications, including:
Sealing glazing units with powder-coated aluminium, ceramic, PVC, painted wood, metal, and brickwork.
Addressing joints with high movement between different building materials, such as timber frames.
Providing exceptional bonding strength for porous surfaces like brick,
block wood, as well as non-porous surfaces like ceramic tiles and glass.
Featuring anti-mould properties, making them suitable for areas with
high humidity, including bathrooms, showers, wet rooms, and kitchens.
Serving as an adhesive for cosmetic trims in sanitary, bathroom, and cleanroom applications.
Offering excellent adhesion around internal window and door frames to emulsion surfaces.

Our extensive colour range is accessible for purchase in any quantity, whether you require a single tube, half box, boxes of 24, or more. Additionally, we offer the flexibility to accommodate specific colour preferences through made-to-order options.

In order to form the most effective seal with your Rainbow RAL Colour Match Sealant, brush or wipe away any dust and debris from the area you are working with.
To ensure a precise, smooth bead of coloured sealant for tile, bathroom or exterior applications, apply masking tape to each side of the joint you’re sealing.
Prepare the sealant tube by cutting an aperture at the tip of its
application nozzle that is the same size as the joint. Cut it at a
45-degree angle.
Attach a sealant gun to the Rainbow tube and, gently squeezing the trigger,
steadily apply the colour sealant from one end of the joint to the
other.
Run a smoothing tool over the bead of freshly applied coloured sealant to give it a smooth finish.
Remove the masking tape after the silicone has cured.
