Important Considerations:
- Minimum can temperature for application: +10 °C.
- Maintain a can temperature within 10 °C of the ambient temperature for optimal foam quality.
- Protect can from direct sunlight and temperatures above +50 °C.
- Moisture is necessary for correct curing. Insufficient moisture can cause post-expansion.
- Do not completely fill hollow sections due to foam expansion.
- Not suitable for use on PE, PP, PTFE, silicone, oil, grease.
- Sika Boom FR is not UV resistant.
- Always read safety and technical recommendations on the can.
Application Instructions:
Substrate Preparation: Substrate must be clean, sound, homogeneous, and free of oils, grease, dust, and loose particles. Remove paint and cement laitance. Pre-dampen the substrate with clean water for proper curing and to prevent secondary expansion. Sika Boom FR adheres without primers.
Cleaning of Equipment: Clean tools immediately with Sika Boom Cleaner and/or Sika Remover-208. Cured material can only be removed mechanically.

Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
