To celebrate, Unicrimp is offering the lucky winner a £250 multi-store voucher.

Leading cable accessories supplier and Scolmore Group company, Unicrimp, has acquired the rights to exclusively distribute the original, multi-surface sealant and adhesive brand, OB1, through the UK electrical wholesale channel.

OB1 is a market-leading, high-spec hybrid construction sealant and adhesive that has a tried and tested formulation which has been used by the trade for over 15 years.

What makes OB1 stand out is its versatility, flexibility and its 24-hour full curing time. It provides an alternative to mastics, wood and PU adhesives, silicones, acrylics and butyl rubber sealants. This one product is capable of bonding and sealing an extensive range of materials, including aluminium, wood and MDF, plastic, metal, steel, mirror, lead, concrete, glass, tile, polycarbon, PVC and felt. OB1 also works in damp conditions and even under water. It contains no solvents, so it will never crack or shrink, can be applied on wet surfaces, painted or moulded and it has a very high bond strength with resistance to fungal and bacterial growth.

OB1’s uses are wide ranging for both external and internal projects. It offers superior bond strength for kitchen worktops and, with its food safe formula – OB1 conforms to ISEGA Standards – it is perfect for use in kitchens and food preparation areas. It will bond and seal marble, granite and quartz worktops and is guaranteed not to attack or stain surfaces. For bathrooms, it features zero VOC’s, so it offers exceptional mould resistant sealing. It will bond skirting and architraves, as well as mirrors without the need for any additional fixings. Its weather-resistant properties make it perfect for outdoor repairs, including leaking gutters and slates, and it will perform flawlessly even when applied under water.

OB1 multi-surface construction sealant and adhesive is available in a 290ml tube, in a range of colours – white, clear, black, anthracite, grey, silver, brown, terracotta and beige.

Also available in the OB1 range is a multi-surface cleaner (aerosol 500ml) and a multi-layer paint and varnish remover (aerosol 500ml).
