Product Questions

  • I am repairing a caravan roof where the end panel meets the main roof panel. I presume the product is self-adhesive. In what sort of temperatures can it be applied? Although he caravan is covered in the wet winter months, it is left uncovered in the summer months and water can sit on the roof. How long will it be before the product becomes ineffective due to the water. Will it last the whole year? - Geoff
  • Hello Geoff, Thank-you for your enquiry. This tape will do the job, and will last well over a year, as long as the tape is applied correctly - Matt, Product Support Manager
  • Hi does this flashing tape do conservatories to brickwork. 99 % sure it does just making sure, as says washing machines and caravans - Wendy
  • Hi Wendy, yes this is the primary application for the flashing tape - Ian, Product Support Manager
  • Hi there. I am in the process of replacing the roof for my conservatory with new polycarbonate. I see that this product is recommended for flashings for this type of work, which is great. I was looking at using something like DEKS KwikFlash or the Hambleside Danelaw FastFlash type products for the ridge and abutment flashings but wondered if you could tell me if the HS Butyl Flashing is the same specification as these products ie is it Aluminium stretch netting cast in polymer rubber for expansion and long term strength? I need a butyl backed flashing (definitely not bituminous!) that will not attack the polycarbonate sheeting. Am pretty certain this is the case with the HS Butyl but can you confirm for me, please? The abutment wall the flashing will go against is stone - again, can you confirm the HS Butyl will adhere satisfactorily to this, please? I should add that, in addition to the butyl flashing for protection against water ingress, I will be dressing over the butyl flashings with Code 4 lead, which will also help weather the butyl flashing. I am concerned, given they are quite a bit more expensive, that the KwikFlash or Fast Flash versions may be unnecessarily 'over specify' in this scenario. If the HS Butyl meets the required specifications for the task in hand then it would be good to avoid what may be seen as an unnecessary expense! I would be most grateful for your thoughts regarding my enquiry and any advice offered would be warmly welcomed. Many thanks and best regards - Laurie
  • Good Morning Laurie, Thank you for your enquiry into the use of our butyl flashing tape. I can confirm that this product is polycarbonate friendly and is used commonly for this type of application. The 1.5mm thick butyl adhesive is very aggressive and conformable, making it the perfect choice for creating a weather seal on uneven surfaces. The elasticity of the butyl will also allow for differential rates of expansion - Ian, Product Support Manager

Product questions for our: DISCONTINUED: Bondloc Plastic Weld Structural Adhesive (A different size of this product)

  • Hi, I need to adhere two sheets of PVC together to obtain a 100% bond (approxsize 500mmx150mm times x4) .Are you able to recommend one of you products? - Brian
  • Hello Brian, Thank-you again for your enquiry. Further to our telephone conversation, I would suggest the Plastic Weld product [this] - Best Regards Matt, Product Support Manager

I would give 5 out of 5 and would not go on a job without either the grey or white Butyl flashing in my tool box.

Excellent solution for repairing leaky conservatory roofs. Had tried everything else and this works a treat. Highly recommended even for the biblical rain weve had recently. Five Stars particularly as its available in white.

Used to seal the troublesome joint between metal and fibreglass on the motor home roof. Instant bonding, excellent adhesion, cured the problem. Would certainly recommend it.

I have used this on my Caravan roof and found it very easy to use. You must make sure the areas are clean and grease free. If you have. Followed the instructions it is a great product and has cured my long running issue with a leaky seam. Great product highly recommended.

Score 5 STARS for everything.
