Dr. Fixit Triflex Glass Fleece
The purpose-built reinforcement fabric that turns a liquid PMMA coat into a genuine crack-bridging membrane — right where roof and terrace details actually fail.
What is it?
A white, micro-perforated 110 g/m² polyester fleece designed to be embedded wet-on-wet into Dr. Fixit’s Triflex PMMA resin to reinforce and crack-bridge critical waterproofing details.
Where is it used?
Parapet and upstand junctions, drain outlets, pipe penetrations, expansion joints and crack-prone RCC areas on terraces, balconies, podiums and large commercial or infrastructure decks.
Why use it?
At detailing points a liquid resin coat alone is only as strong as its ability to bridge micro-movement; the fleece adds tensile reinforcement without trapping air, because its micro-perforations let the resin pass through cleanly.
How is it applied?
Cut to length and width on site, laid into the freshly applied Triflex PMMA base resin, saturated and pressed down wet-on-wet to remove creases and air voids, then given a second saturation coat, with strips overlapped a minimum 5 cm using the printed lettering as an overlap guide.
About Dr. Fixit Triflex Glass Fleece
Every terrace, balcony or podium deck in Delhi NCR has the same weak points — the corner where a parapet meets the slab, the collar around a rainwater outlet, the hairline crack that opens up every monsoon at a construction joint. A liquid waterproofing coat by itself can only stretch so far before it splits at these spots. Dr. Fixit Triflex Glass Fleece solves that specific problem: a 110 g/m² micro-perforated polyester fabric, engineered to be laid into a wet coat of Dr. Fixit’s Triflex PMMA resin and saturated through, so the fleece and resin cure into one reinforced, crack-bridging layer rather than two separate materials sitting on top of each other. The micro-perforations aren’t cosmetic — they let the resin punch through the fabric cleanly, so you don’t end up with the trapped air pockets or dry patches that turn into blisters and pinhole failures later.
It’s a system component, not a standalone product — the fleece is engineered, and legally protected (Pidilite lists it as utility-model protected), specifically to work with the Triflex PMMA resin and catalyst, the fast-curing detailing system Dr. Fixit positions for large commercial and infrastructure projects where downtime matters. As an authorised Dr. Fixit distributor and applicator across Delhi NCR, Space Arc supplies the fleece alongside the Triflex resin and catalyst as a complete detailing kit, and our site teams are trained on the wet-on-wet embedding technique the technical data sheet calls for — because a fleece that’s laid dry, or saturated unevenly, won’t give you the tensile reinforcement the system is bought for in the first place.
The technical insight
One detail worth flagging for anyone specifying this off the datasheet: despite “Glass” sitting in the product name, Pidilite’s own technical property table lists the material form as “Perforated Polyester Fleece” — not woven glass fibre. That’s not a red flag; PMMA waterproofing systems have used “glass fleece” as a generic trade term for reinforcing fabric for decades, and the naming has carried over even where the actual fibre is polyester. But if a structural submittal or a client’s spec sheet specifically calls for glass-fibre reinforcement, it’s worth confirming this distinction with the Dr. Fixit technical desk before ordering. The other detail that matters on site: the printed “Triflex” lettering running along the fabric isn’t a logo, it’s an install aid — it marks the direction and the minimum 5 cm overlap the TDS requires at every strip transition, which is exactly where under-lapped fleece tends to fail first.
Where it is used
- Parapet-to-slab and upstand detailing on RCC terraces and balconies
- Rainwater outlet and pipe-penetration collars on roof decks
- Reinforcement across expansion and construction movement joints
- Crack-bridging over hairline and shrinkage cracks before the final Triflex resin topcoat
- Internal and external corner/angle reinforcement at wall-to-floor junctions
- Podium deck and basement waterproofing detailing under car parks and landscaping
- Fast-track waterproofing on large commercial, retail and infrastructure projects
- Detailing around AC ducting, rooflights and other roof service penetrations
Key advantages
- Micro-perforated design lets resin saturate fully through the fabric, avoiding trapped air and pinhole risk
- Light 110 g/m² polyester construction drapes cleanly around corners, collars and other awkward detail geometry
- Utility-model-protected perforation pattern — purpose-engineered for PMMA, not a generic construction scrim
- Printed directional “Triflex” lettering gives site crews a built-in overlap guide, cutting installer error
- Cures into one monolithic reinforced membrane with the resin rather than sitting as a loose mesh underneath it
- Genuine tensile/crack-bridging capacity at the movement-prone junctions where liquid coatings alone crack first
- Narrow roll format is efficient for linear detailing work — cut to length, minimal wastage on joints and collars
- Backed by Pidilite’s Dr. Fixit technical desk and Space Arc’s trained on-site application crew
Limitations & considerations
- Only validated for use with Dr. Fixit’s own Triflex PMMA resin and catalyst — not a general-purpose reinforcing fabric for other waterproofing chemistries
- PMMA resin’s short pot life means this is a trained-applicator product, not something a site crew should attempt without prior Triflex-system training
- 0.52 m roll width means more strips and overlaps across a large open field area than a purpose-made wide-format sheet would need
- Named “Glass Fleece” but the technical data sheet lists the material as polyester, not woven glass fibre — confirm with Dr. Fixit if a spec strictly calls for glass fibre
- Positioned for detailing and critical junctions rather than blanket full-roof waterproofing, so it adds cost if specified beyond where it’s actually needed
- Public TDS doesn’t publish tensile strength, elongation or fire-rating figures — get project-specific data from Pidilite for formal specification submittals
Selection & best practice
The technical data sheet is explicit that this fleece is only ever used wet-on-wet — never dry-laid and coated over later. Prep the Triflex PMMA base resin coat per its own TDS and method statement, cut fleece strips to the actual detail length before you start (working time on PMMA resin is short), embed the fleece into the wet resin and press it down firmly to chase out every crease and air void, then run the second saturation coat while the first is still workable. Keep every overlap at a genuine 5 cm minimum, using the printed lettering as your guide, and don’t skip corners or pipe collars — these are exactly the points the fleece exists to reinforce. Because pot life and ambient temperature both affect PMMA working time, this isn’t a first-time DIY job; Space Arc runs this as a trained applicator crew rather than handing rolls to an untrained site team.

How we position Dr. Fixit Triflex Glass Fleece
Dr. Fixit Triflex Glass Fleece is sold and applied as part of the Triflex PMMA family — the Triflex base resin and Triflex Catalyst it must be embedded into — and Space Arc supplies all three together as a detailing kit rather than as isolated line items, which is how Pidilite intends the system to be used. For projects that need crack-bridging reinforcement but aren’t committed to a PMMA route, specifiers in Delhi NCR sometimes compare it against polyurethane or polyurea liquid-membrane systems from brands like Fosroc, which use their own compatible reinforcing fabrics; that’s a genuinely different chemistry with its own cure profile and cost, not a drop-in substitute for the Triflex fleece, so the choice usually comes down to project timeline and whether PMMA’s fast cure is worth the premium.
