Protecta FR Acrylic 4hr Intumescent Sealant, part of the Protecta Firestopping range, is designed to prevent the spread of fire and smoke through joints and openings in fire rated walls and floors including openings formed around building service penetrations. It will also maintain the acoustic design performance in walls and floors.
The sealant cures when it is subjected to atmospheric conditions, however it will retain a degree of elasticity for joint movement. Under fire exposure, it creates a robust fire seal by the formation of a durable intumescent char.
Protecta FR Acrylic 4hr Intumescent Sealant can be used with a suitable filling material, i.e. stone wool or Protecta Backing material in order to secure correct width to depth ratio and to reduce the shrinking of the sealant during curing. Minimum depth and maximum width of the joints are included in the installation instructions. Thermal activation takes place at about 180°C when the material will expand (intumesce) and prevent the passage of fire and smoke for periods up to and beyond 4 hours.
NEW - Eco-Foil System
The system works by inserting a 300ml foil into the reusable Eco-Cartridge, which fits into a standard skeleton gun. The cartridge has a double-ended plunger, so once the foil is empty, remove the cap and nozzle and re-fill the opposite end with a new 300ml foil. Simply replace the cap and nozzle at the opposite end, insert into the dedicated foil gun and the system is ready for use!
- One Eco-Cartridge can be reused a minimum of 60 times
- Reduces on-site waste by more than 90%
- The system fits into a standard skeleton gun
- 6 months longer shelf life than the same product in a cartridge

For linear seals without services, please refer below to Resistance to Fire – Linear Seals. For guidance on fire sealing ventilation ducts, please refer to Protecta FR Damper’s Technical Data Sheet.
Minimum separations and limitations:
Services can be sealed as specified in the detailed drawings. Minimum separation between services and also between services and the edge of the seal within each aperture should be 10 mm to allow for correct fitting of backing and seal depth. Minimum separation between apertures should be at least 30 mm. For larger joint dimensions or apertures other than described in the detailed drawings, Protecta FR Board or EX Mortar should be used. In areas with a high degree of humidity and/or in joints with excessive movement, Protecta FR IPT should be used.
Supporting constructions:
Flexible walls must have a minimum thickness of 75mm and comprise steel studs or timber studs* ) lined on both faces with minimum 1 layer of 12.5mm thick boards.
Timber walls must have a minimum thickness of 100mm and comprise solid wood or cross- laminated timber.
Rigid walls must have a minimum thickness of 75mm and comprise concrete, aerated concrete or masonry, with a minimum density of 650 kg/m³.
Rigid floors must have a minimum thickness of 150mm (except composite floors) and comprise aerated concrete or concrete with a minimum density of 650 kg/m³.
Timber floors must have a minimum thickness of 150mm and comprise solid wood or cross- laminated timber. The supporting construction must be classified in accordance with EN 13501-2 for the required fire resistance period.
*** Timber studs: no part of the penetration seal may be closer than 100 mm to a stud, and minimum 100 mm of insulation of class A1 or A2 according to EN 13501-1 must be provided within the cavity between the penetration seal and the stud.
- Before installing Protecta FR Acrylic ensure that the surface of all service penetrations and surrounding construction is free from all loose contaminants, dust and grease.
- Where Protecta FR Acrylic is to be installed against surfaces that cannot tolerate direct contact; appropriate surface preparation should be made (contact Polyseam/Rawlins Technical (0113 2455450, option 2 or [email protected]) for guidance in these cases). For paints sensitive to sealing compounds, priming with a PVA primer is recommended.
- As Protecta FR Acrylic is water based, in cases where corrosion protection is a problem; some metals may require a barrier between the sealant and the metal surface prior to this installation.
- When installing the sealant in gypsum boards, the exposed edges of the board can be wetted with water, or Protecta FR Acrylic diluted with water to prime the surfaces helping adhesion and preventing excessive joint shrinkage.
- When installing Protecta FR Acrylic in hollow floor slabs or boards, fire seals specified as single sided should be installed from the soffit side of the floor assuming there is sufficient thickness of concrete below the void to follow the installation guide. Where this is not the case, tubular voids should be filled with stone wool normally the same thickness as the depth of the floor slab. Alternatively, simply fire seal on both sides.
- When installing any backing material, cut this slightly oversize and insert into the gap ensuring a tight friction fit. Ensure correct depth is achieved.
- Fill the gap or joint with Protecta FR Acrylic to the required depth. Refer to the drawings on following pages 2 to 37 for guidance on joint design/dimensions. If installation does not have to meet any specific fire specification, it is recommended that a width to depth ratio of 2:1 is utilized, with a minimum depth of 12mm of sealant.
- Apply the sealant generously to prevent air bubbles. Finish the bead with a moist spatula, pallet knife or brush.
- Protecta FR Acrylic can be over-painted with most emulsion or alkyd (gloss) paints.

Protecta FR Acrylic complies with the requirements of GEV and the results correspond to the EMICODE emission class EC 1PLUS which is the best possible environmental and indoor hygiene health protection mark. Tested by Eurofins Product Testing, report number G12870B.
Analysis of cPVC Pipes e.g. BlazeMaster
Analysed using Fourier Transform Infrared (FTIR) Spectroscopy; examination of the sealant contact regions of the cPVC pipe after removal of the sealant showed no evidence of visible discolouration or changes at the pipe surface.
Protecta FR Acrylic has also been tested for chemical resistance of a sealant when applied to a cPVC pipe. The sealant does not affect cPVC pipes as the tests showed no difference between the control and exposed results at Yield.
Tested by Intertek, report numbers IWTN/W000009628ARL001 and WTN/W000009628RLM001.

Pipe End Configurations
When testing pipes, one can choose not to cap (or close) the pipe, or cap the pipe inside the furnace, or outside the furnace, or on both sides. The configuration chosen depends on the intended application of the pipe and/or the installation environment. The code defining if a pipe is capped is stated after the fire classification. For instance EI 60 C/U which means the pipe was capped inside the furnace, and uncapped outside the furnace. The test configuration defines the approvals possible.
