About RAL Sealants

RAL Sealants is a UK specialist supplier of RAL coloured silicone and sealants for trade, commercial and domestic projects.

We help installers, fabricators, contractors and homeowners find a precise colour match for windows, doors, cladding, aluminium frames and general finishing work, with fast UK delivery and specialist service.

Standard white or grey sealant can spoil an otherwise carefully finished window, door or cladding job. That's why we colour-match our silicone sealant to the RAL Classic range, so the sealant line blends into the frame or panel instead of standing out against it.

Our range

We stock 65 of the most popular RAL colours ready to order online, and offer a Custom Made Silicone service for any RAL, Farrow & Ball or Dulux Heritage colour we don't hold as standard stock — made to order and matched to your exact reference.

Who we work with

We supply trade installers and fabricators ordering regularly or in bulk, alongside homeowners and DIY customers completing a single repair or renovation — every order gets the same colour accuracy and service, whatever the size.
