Butyl tapes and strips are extremely popular sealing materials used in construction, industry, automotive applications, and plumbing systems. However, their effectiveness depends not only on product quality but also on proper application. In this article, we outline the most common mistakes when applying butyl tapes and strips and offer tips on how to avoid them.
1. Unprepared Surface – The Enemy of a Proper Seal
Applying tape to a dirty, greasy, or damp surface significantly reduces the effectiveness of the seal.
🔧 How to fix it?
Always thoroughly clean and dry the surface before applying the tape. Butyl tapes and strips adhere best to clean, degreased, and dry surfaces.
2. Incorrect Application Temperature
Conditions that are too cold or too hot can negatively affect the adhesive properties of the butyl material.
🌡 Recommendation:
Apply butyl tapes and strips at a temperature between +5°C and +35°C, in accordance with the manufacturer’s guidelines.
3. Insufficient Pressure During Application
Inadequate pressure during installation can result in air gaps and poor adhesion, leading to leaks.
🛠 How to avoid it?
Always press the butyl tape evenly along its entire length – ideally using a pressure roller.
4. Choosing the Wrong Type of Tape or Strip
Not every butyl product is suitable for every application. Picking the “first available” tape often ends in failure.
📌 Best practice:
Select butyl tapes and strips that match the specific working environment – whether for indoor or outdoor use, UV resistance, or flexibility for moving joints.
5. Gaps and Leaks Between Tape Sections
Leaving gaps between tape segments is a common and costly mistake.
📏 How to avoid it?
Always apply butyl tapes continuously. If you need to join sections, make sure they overlap by at least 1–2 cm.
Summary
Proper application is crucial to the performance of any sealing material. Avoiding the most common mistakes ensures that butyl tapes and strips serve their sealing function effectively for many years – without the need for repairs or replacements.
