Details
Acryl Fire Resistant is a single-component acrylic sealant consisting of acrylic polymers dispersed in a water base together with selected minerals. This formula gives the hardened product a high resistance to fire. When the product is applied, the water base evaporates leaving a flexible, plastic mass with excellent resistance to ageing. Acryl Fire Resistant adheres to damp surfaces, does not drip and is easy to smooth. It can be applied indoors or outdoors but only in places where there is no continuous contact with water. Acryl Fire Resistant can be coated with water-based paints or coatings. The product is certified as EC 1 Plus by GEV in terms of very low emissions of volatile organic substances.
Instructions for use
Joint size: Certified joints must follow the geometry given in the official product classification reports.
- The sides of the joint must be solid and clean. Acryl Fire Resistant does not require a primer. It is advisable to wet porous surfaces beforehand. During hot weather, wet the substrate. It is also advisable to prime critical surfaces with a primer coating consisting of one part sealant to 10 parts water. This will improve adhesion of the sealant. Deep expansion joints must be plugged with suitable pre-forms.
- Tape along the sides of the joint.
- Use a mechanical or a pneumatic gun loaded with the bag to inject the product into the joint. Use an extruder nozzle diameter which matches the joint to be filled.
- We recommend that you overfill the joint cavity with sealant.
- When you smooth the sealant apply pressure to force the sealant into the joint. This will ensure that the joint is filled fully without leaving any gaps and that the sealant adheres completely to the sides of the joint. Smooth off before the sealant has a chance to form a surface film.
- Remove the tape.
Cleaning
Tools used with Acryl Fire Resistant are easy to clean with water while the product is still soft. Hardened product can only be removed mechanically or by using an organic solvent (e.g. toluene, acetone).
Storage
Protect against frost. In the original unopened packaging and stored at temperatures between +5 °C and +35 °C, Acryl Fire Resistant is stable for at least 24 months. Not completely emptied bags can be stored for about 3 months, if closed properly.
Warnings
The material cures through water evaporation: the sealant loses its initial tackiness within 20 to 120 minutes, depending on environmental conditions. Low temperatures and high relative humidity will slow down hardening. High temperatures and low relative humidity will accelerate hardening. Do not apply Acryl Fire Resistant when it is about to rain: the applied sealant, not yet cured, can be washed away. Sealant that has not fully cured will be damaged by frost.
