ThermTac offers two versatile primer options – Liquid Primer and Spray Primer – meticulously designed to ensure optimal adhesion and longevity for your preformed thermoplastic markings. Let's dive into the usage guidelines to help you achieve long-lasting installations every time!
ThermTac Liquid Primer:
- Ideal for installations on concrete, block paving, or worn/dusty bituminous surfaces.
- Begin by thoroughly cleaning the application area, removing all sand, dirt, and chemicals to ensure a pristine surface.
- Using a suitable propane torch, eliminate any moisture and preheat the area prior to treatment.
- Apply ThermTac Liquid Primer with a small, short/medium pile roller or brush, ensuring a thin coating covers the substrate where the marking will be placed.
- For concrete surfaces that absorb primer quickly, multiple coats may be necessary.
- Allow approximately 15 minutes for the primer to air dry, although drying times may vary depending on ambient temperatures.
- Once the primer is dry/tacky to the touch, you're ready to apply the markings on top using a propane torch.
ThermTac Spray Primer:
- Recommended for small applications or reinstatements with Rolls, providing additional adhesion in targeted areas.
- Follow the same preparation steps as with Liquid Primer, ensuring the application area is thoroughly cleaned and preheated.
- Apply ThermTac Spray Primer directly from the spray can, coating the substrate where the marking will be placed. Multiple coats may be required for desired coverage.
- Allow approximately 10 minutes for the primer to air dry, with drying times subject to ambient temperatures.
- Once dry/tacky to the touch, proceed to apply the markings on top using a propane torch.
FAQ:
- How long does primer take to dry?
- Liquid: Approximately 15 to 20 minutes.
- Spray: Typically 5 to 10 minutes, depending on the number of layers applied. Ambient temperatures may affect drying times.
- What type of concrete should be primed?
- All concrete surfaces should be primed before installing preformed thermoplastic markings.
- What type of Tarmac/Asphalt should be primed?
- Any old or worn bituminous surface rich in aggregates should be primed.
- How should I prepare the site?
- Ensure the site is clear of loose debris, dust/dirt, and surface chemicals. The substrate should be dry and free from moisture.
- Can I apply on Block Paving?
- While priming is essential, it's important to note that thermoplastic markings have a shorter lifespan on block paving due to movement between blocks and susceptibility to moisture ingress.
