What we particularly like about the Brewers sealant though, is how well it works even on damp surfaces. It’s also mould resistant and safe to use in food preparation areas. The sealant only comes in white, though and while it is paintable, we’d like to see it in a wider range of colours – or at least a clear version.

Key details – Size: 310ml; Colours: Clear, white and Manhattan grey; Suitable for: All-purpose; Application method: Sealant gun Use pressure – If you’re sealing two pieces of metal together, you’ll need to apply pressure to ensure the sealant forms a strong bond. We recommend using a vice or clamp to hold the pieces together firmly.Clean surfaces – Clean surfaces thoroughly before using sealant, as residues can prevent a solid bond forming. You should also ensure surfaces are dry before application. Use a primer where possible – Primers don’t have a very long shelf life, but they can help improve the adhesion of your sealant. Brewers’ sealant is our top all-rounder choice because there aren’t any surfaces it can’t safely be used on. What’s more, as it’s a combined sealant and adhesive, it has even more uses and eliminates the need for multiple products. It’s suitable for indoor and outdoor use, sealing joints around sanitary fixtures and can be used on perimeter joints around window and door frames too. You can use it for glueing panels, skirting boards, thresholds and insulation materials. It can also be used to seal and bond glass, porcelain, coated metal, epoxy and polyester panels, covered polystyrene, PVCu, stainless steel, anodised aluminium and finished wood. Phew.

Shelf life – Silicone sealants won’t keep forever in their tube as once the sealant is exposed to the elements. Keep nozzles attached at all times and if you live in a hot and humid environment, keep your silicone sealant in the fridge.
