How to apply Butyl Tape?

Butyl seal tape is simple to apply. Firstly, ensure your surface is clean and grease and dirt-free. Once it is, please remove it from the liner, mould it into position and leave it to set. It is as simple as that.

How to clean / remove butyl tape residue

To clean butyl tape residue effectively, start by gently scraping off as much of the excess tape as possible using a plastic scraper or putty knife, being careful not to scratch the surface.

Next, apply a solvent such as rubbing alcohol, mineral spirits, or a commercial adhesive remover onto a clean cloth and dab it onto the residue. Let the solvent sit for a few minutes to soften the adhesive. Afterwards, wipe the area clean with a cloth.

If some residue remains, repeat the process. Finally, wash the area with soapy water and dry it with a clean towel to remove any solvent traces.

Always test the solvent on a small, inconspicuous area first to ensure it does not damage the surface.

What is Butyl made up of?

Butyl tape is a type of sealing tape used for various applications, including sealing, waterproofing, and soundproofing. It is made of a rubber-like butyl material, which is highly effective in creating an airtight and watertight seal.

Questions people have asked us about these butyl tapes

Product questions for our 100mm x 1.5mm x 20 Metre Flashing Tape

Question: I will be undertaking a self-build timber frame and timber-clad project. I intend to use Andersen 400 windows (an American company) with a nailing flange. In the instructions, they mention self-healing flashing and looking at various American websites, Tyvek Flex-wrap flashing for the sill and Tyvek straight flashing for sides and top are used. Whilst Tyvek flex-wrap is available in the UK, only 150mm width is available, not 250mm, and Tyvek straight flashing is unavailable. Can you recommend a butyl flashing for weather protection and air leakage, and that is self-healing butyl because some mechanical fixings on the vertical sections would penetrate the flashing? I look forward to hearing from you however if you need further information, please do not hesitate to contact me. - Stephen

Answer: Morning Stephen, I feel that [this] flashing tape would help with this application as the adhesive is self-healing and 1.5mm thick. We do stock lead and white finishes in 200mm widths - Ian, Product Support Manager

Question: I need flashing tape for sealing my poly carb roof to the wall. Is 200mm x 1.5mm x 10 Metres Flashing Tape the best choice? - Tony

Answer: Hi Tony, yes, the 200mm would be perfect for this application, then decide on a facing colour of either white or lead - Ian, Product Support Manager

Question: Can this product stretch to form corrugated roofing panels? - Live Chat

Answer: Hello, the product won't stretch as it is a butyl-backed foil. It is very conformable, though - Ian, Product Support Manager

Question: Will it bend sideways 90 degrees down the length of 100x125mm timber? i.e. form an upside-down U-shape, or will it crack or break at the bends? - Live Chat

Answer: Hello, and thank you for your enquiry. The product would be fine for this application - Ian, Product Support Manager

Product questions for our: 150mm x 1.5mm x 10 Metre Flashing Tape

Question: Hi, does this flashing tape do conservatories to brickwork? 99 % sure it does, just making sure, as it says washing machines and caravans - Wendy

Answer: Hi Wendy, yes, this is the primary application for the flashing tape - Ian, Product Support Manager

Question: Hi there. I am in the process of replacing the roof for my conservatory with new polycarbonate. This product is recommended for flashings for this type of work, which is great. I considered using DEKS KwikFlash or the Hambleside Danelaw FastFlash-type products for the ridge and abutment flashings. Still, is the HS Butyl Flashing the same specification as these products, i.e., its 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. 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? In addition to the flashing tape for protection against water ingress, I will dress over the flashings with Code 4 lead, which will also help weather the butyl flashing. Given that they are quite a bit more expensive, I am concerned that the KwikFlash or Fast Flash versions may be unnecessary 'specify' in this scenario. If the HS Butyl meets the required specifications for the task, then avoiding what may be considered unnecessary expenses would be good! I would be grateful for your thoughts regarding my enquiry, and any advice offered would be warmly welcomed. Many thanks and best regards - Laurie

Answer: Good Morning Laurie, Thank you for enquiring about using our flashing tape. I can confirm that this product is polycarbonate friendly and is commonly used for this application type. 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
