Left untreated, those fibres become airborne — creating a health hazard for building occupants and triggering legal obligations under the Asbestos Abatement Regulations 2020. Rhinoluxe Asbestos Fiber Lock asbestops encapsulation primer is a water-based, penetrating primer that soaks into the porous asbestos matrix, binds loose fibres in place and seals the substrate against moisture, moss and lichen without the disruption or cost of full removal.\u003c\/p\u003e\n\u003ch2\u003eKey Benefits\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePenetrating Fibre Lock-Down, Not Just a Surface Film.\u003c\/strong\u003e The low-viscosity formula travels into the pores and micro-cracks of weathered asbestos, creating a three-dimensional bond within the substrate itself. Bridging membranes sit on top of the surface and rely on adhesion alone. Rhinoluxe Asbestos Fiber Lock anchors from within, locking friable fibres at their source.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIntegrated Algicidal and Fungicidal Dry-Film Protection.\u003c\/strong\u003e Moss, lichen and algae use root-like structures called rhizoids to physically pry asbestos fibres apart. Asbestos Fiber Lock contains algicidal and fungicidal agents that remain active in the cured film, preventing biological regrowth from undermining the encapsulation layer over time. This is not a wash-off pre-treatment — the protection is built into the primer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWater-Based, Non-Flammable Handling.\u003c\/strong\u003e The product disperses in water and carries no flammable solvent classification. This simplifies storage, transport and on-site handling compared to solvent-based alternatives, particularly on occupied residential and institutional buildings where open-flame restrictions apply.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUniversal Bonding Stage for Multiple Topcoat Systems.\u003c\/strong\u003e Rhinoluxe Asbestos Fiber Lock creates the correct adhesion foundation for Shield waterproofing membrane, Fiber Coat fibre-reinforced coating and Premium Roof and Wall acrylic topcoat. One primer supports multiple finishing options depending on the project specification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEncapsulation at a Fraction of Removal Cost.\u003c\/strong\u003e Full asbestos roof removal in South Africa typically costs R300–R600 per square metre once demolition, disposal, replacement sheeting and compliance documentation are factored in. A Biocide treatment followed by a two-coat Rhinoluxe Fiber Lock system and finished with a protective topcoat delivers effective encapsulation at substantially lower cost, keeping the building operational throughout the process.\u003c\/p\u003e\n\u003ch2\u003eTechnical Overview\u003c\/h2\u003e\n\u003cp\u003eRhinoluxe Asbestos Fiber Lock is a water-based penetrating primer and sealer. The product is designed specifically for weathered asbestos-cement substrates including corrugated asbestos roofing sheets, flat sheeting, fascia boards and downpipes.\u003c\/p\u003e\n\u003cp\u003eThe chemistry provides two advantages over standard acrylic primers. The Asbestos Fiber Lock delivers superior alkali resistance, preventing saponification (chemical breakdown of the resin) in the highly alkaline environment of asbestos cement. The acrylic component provides flexibility, allowing the cured film to move with thermal expansion and contraction without cracking.\u003c\/p\u003e\n\u003cp\u003eThe product is thixotropic: it thins under spray pressure for maximum penetration into the substrate, then recovers its body once deposited on the surface. This prevents run-off on sloped corrugated roofing and ensures uniform coverage across peaks and valleys. The clear satin finish does not alter the colour of the substrate, making Rhinoluxe Asbestos Fiber Lock suitable as a transparent bonding stage beneath any approved topcoat colour system.\u003c\/p\u003e\n\u003cp\u003eThe product is classified as non-hazardous for transport and storage. The substrate is the hazard, not the primer. All asbestos-related work must comply with the Asbestos Abatement Regulations 2020 and be carried out by competent personnel using appropriate personal protective equipment including FFP2 respirators and disposable coveralls.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eProperty\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003ePenetrating Primer and Sealer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChemical Base\u003c\/td\u003e\n\u003ctd\u003eAcrylic Co-Polymer (Water-Based)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAppearance\u003c\/td\u003e\n\u003ctd\u003eClear Thixotropic Liquid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eSmooth Clear Satin to Medium Sheen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoverage\u003c\/td\u003e\n\u003ctd\u003e7–10 m²\/L per coat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSurface Dry\u003c\/td\u003e\n\u003ctd\u003e1 Hour\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHard Dry\u003c\/td\u003e\n\u003ctd\u003e4 Hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecoat Time\u003c\/td\u003e\n\u003ctd\u003e4 Hours minimum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpecific Gravity\u003c\/td\u003e\n\u003ctd\u003e0.991–1.031\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eViscosity\u003c\/td\u003e\n\u003ctd\u003e70–75 KU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNon-Volatile Content\u003c\/td\u003e\n\u003ctd\u003e33–35% by volume\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlammability\u003c\/td\u003e\n\u003ctd\u003eNon-Flammable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHazardous Goods Classification\u003c\/td\u003e\n\u003ctd\u003eNot Classified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable Substrates\u003c\/td\u003e\n\u003ctd\u003eAsbestos Cement Roofing, Flat Sheeting, Fascia Boards, Downpipes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication Method\u003c\/td\u003e\n\u003ctd\u003eAirless Spray (preferred), Brush or Roller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClean-Up\u003c\/td\u003e\n\u003ctd\u003eClean Water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackaging\u003c\/td\u003e\n\u003ctd\u003e5 L and 20 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eApplication Method Statement\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eStep 1 — Sterilise the Surface.\u003c\/strong\u003e Spray Rhinoluxe Biozide Steriliser onto the entire asbestos cement surface to kill moss, lichen, algae and fungal spores. Allow a minimum of 24 hours for the biocide to take effect.

Do not thin with water — dilution reduces bonding power and compromises fibre lock-down. Allow a minimum of 4 hours drying time between coats, then apply the second coat. The two-coat system ensures full penetration and saturation of the weathered cement matrix.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStep 3 — Apply Two Coats of Protective Topcoat.\u003c\/strong\u003e Once the second coat of Fiber Lock has reached hard dry (minimum 4 hours), apply two coats of your selected Rhinoluxe topcoat system: Shield waterproofing membrane, Fiber Coat fibre-reinforced coating or Premium Roof and Wall acrylic topcoat.

The TDS states clearly: do not dilute with water. Adding water reduces the polymer concentration in the film, weakens the fibre bond and produces a powdery finish that fails under tape-pull testing. Stir well before use to distribute the algicidal and fungicidal components evenly through the product.\u003c\/p\u003e\n\u003cp\u003eSpray application using an airless sprayer delivers the most consistent coverage on corrugated roofing. The thixotropic formula thins under spray pressure and recovers on contact with the surface, preventing sag and run-off on sloped sheets. Brush and roller application are acceptable for flat sheeting, fascia boards and small repair areas.\u003c\/p\u003e\n\u003cp\u003eAvoid application during cold, wet or excessively humid conditions. Damp substrates trap moisture beneath the primer film, causing blistering when the roof heats up in direct sun. Plan your application window for dry weather with surface temperatures between 10°C and 35°C. Bare asbestos cement dries quickly after rain, but check that no moisture is weeping from the underside before coating.\u003c\/p\u003e\n\u003cp\u003eRhinoluxe Asbestos Fiber Lock is not suitable for chalky or powdery surfaces where the cement matrix has degraded beyond recovery. Test a small area first: the primer should absorb into the substrate and dry to a clear satin finish. A white, powdery result indicates the surface is too far gone for encapsulation and professional assessment is required.\u003c\/p\u003e\n\u003cp\u003eThe product is not designed for use on metal substrates. Galvanised flashings, screws and ridge caps adjacent to asbestos sheeting require separate treatment with Rhinoluxe MultiPrime or ZP4 Zinc Phosphate Primer.\u003c\/p\u003e\n\u003cp\u003eAll asbestos-related work must comply with the Asbestos Abatement Regulations 2020. Personnel must wear FFP2 respirators, disposable coveralls, gloves and safety eyewear. Do not sand, grind or pressure-wash asbestos surfaces — these methods are prohibited because they release fibres into the environment. The penetrating nature of Rhinoluxe Fiber Lock eliminates the need for aggressive surface preparation.\u003c\/p\u003e","brand":"Rhinoluxe","offers":[{"title":"5L","offer_id":53855438307603,"sku":"R-AFL-5L","price":560.0,"currency_code":"ZAR","in_stock":true},{"title":"20L","offer_id":53855438340371,"sku":"R-AFL-20L","price":1880.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0657\/3434\/4938\/files\/20L_Plastic_Paint_Drum-Asbestos_Fiberlock_d0c63fb1-87ec-462a-aaaf-f0ffca43b1d3.png?v=1771854331","url":"https:\/\/rhinoluxe.co.za\/products\/asbestos-fiber-lock","provider":"Rhinoluxe","version":"1.0","type":"link"}
