When a membrane is fixed to a wall, every drilled fixing point creates a potential route for moisture transfer if it is not correctly sealed, and these washers have been developed to address precisely that risk. By sitting around the head of the fixing plug and compressing firmly against the membrane surface as the plug is driven home, they help create a reliable watertight seal around each fixing penetration. This is particularly valuable in higher moisture-risk damp proofing situations and in below-ground \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/collections\/platinum-basement-waterproofing\" target=\"_blank\"\u003e\u003cstrong\u003ewaterproof membrane\u003c\/strong\u003e\u003c\/a\u003e installations where fixing penetrations must be properly protected against water ingress.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eFlexible Compressible TPE Construction Compatible With Platinum Plug Range\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eManufactured from high-quality Thermoplastic Elastomer, Platinum Plaster Plug Sealing Washers provide a flexible, compressible seal that conforms closely around the plug head during installation, helping to maintain consistent contact between the washer and the membrane face.

Platinum Plaster Plug Sealing Washers offer a clean, repeatable and easy-to-control sealing method that provides a practical and consistent alternative to relying solely on mastic or rope sealants, making them a useful and dependable accessory for installers who need confidence in every fixing detail across the full extent of the membrane

When a fixing plug is driven through a membrane and into the substrate, the drilled hole can become a potential route for moisture movement if it is not sealed correctly. These washers sit around the plug head and compress against the membrane face as the fixing is installed. This helps block water or damp from tracking through the fixing point, supporting the overall integrity of the membrane system and giving installers a simple, repeatable way to improve protection around plug penetrations.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Which fixing plugs are Platinum Plaster Plug Sealing Washers used with?\u003c\/h3\u003e\n\u003cp\u003eA) Platinum Plaster Plug Sealing Washers are primarily used with \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/platinum-mesh-fix-plugs-damp-proof-membrane-fixings\" target=\"_blank\"\u003e\u003cstrong\u003ePlatinum Mesh Fix Mesh Membrane Plugs\u003c\/strong\u003e\u003c\/a\u003e when fixing \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/collections\/damp-proof-membrane-platinum\" target=\"_blank\"\u003e\u003cstrong\u003ePlatinum damp proof membranes\u003c\/strong\u003e\u003c\/a\u003e to internal masonry walls.

The washer is placed onto the fixing plug before the plug is installed through the membrane and into the drilled substrate. As the plug is hammered into position, the washer is squeezed between the plug head and the membrane surface. This compressive action helps the Thermoplastic Elastomer material conform around the contour of the plug head and the membrane face, reducing the risk of water or moisture passing through the fixing penetration. For the washer to work correctly, the plug must be installed firmly, the drilled hole must be suitable, and the membrane surface should be clean and properly seated.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) When should Platinum Plaster Plug Sealing Washers be used?\u003c\/h3\u003e\n\u003cp\u003eA) Platinum Plaster Plug Sealing Washers should be used where additional sealing around membrane fixings is required.

In standard low-risk applications, sealing may not always be necessary, but where moisture levels are higher, where the wall is more damp, or where protection around every fixing matters, these washers provide a clean and practical solution.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Are Platinum Plaster Plug Sealing Washers suitable for basement waterproofing?\u003c\/h3\u003e\n\u003cp\u003eA) Platinum Plaster Plug Sealing Washers can be suitable for selected basement waterproofing details, particularly when used with \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/platinum-brick-plugs-without-seals-membrane-fixing\" target=\"_blank\"\u003e\u003cstrong\u003ePlatinum Brick Plugs Without Seals\u003c\/strong\u003e\u003c\/a\u003e where a sealed fixing is required. In below-ground applications, membrane penetrations must be treated carefully because water pressure, damp masonry and moisture movement can make unsealed fixings a weak point. The washer helps create a water-resistant seal around the plug head, supporting the membrane installation. However, the full waterproofing system must still be correctly designed. These washers are only one part of the fixing detail, and they should be used alongside the correct membrane, plugs, drainage approach and installation method for the specific basement or retaining wall situation.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Are Platinum Plaster Plug Sealing Washers an alternative to Platinum Waterseal Rope or Newtonite 801 Mastic?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Platinum Plaster Plug Sealing Washers provide a practical alternative to \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/waterseal-sealing-rope\" target=\"_blank\"\u003e\u003cstrong\u003ePlatinum Waterseal Rope\u003c\/strong\u003e\u003c\/a\u003e and \u003ca rel=\"noopener\" href=\"https:\/\/www.platinumchemicals.co.uk\/products\/newton-mastic-sealant\" target=\"_blank\"\u003e\u003cstrong\u003eNewtonite 801 Mastic\u003c\/strong\u003e\u003c\/a\u003e in situations where a washer-based fixing seal is preferred. They are especially useful when installers want a consistent, repeatable seal around multiple plug fixings without applying mastic or rope around each fixing point by hand. The washer is fitted directly onto the plug and seals as the plug is driven home, which can make installation faster and cleaner. However, the best option depends on the detail.

They should be used only where the washer can compress evenly against the membrane face. If the substrate is uneven, the plug is poorly installed, the hole is oversized or the membrane is not sitting correctly, the seal may be less effective. They should also be selected as part of the correct damp proofing or waterproofing specification rather than treated as a universal solution for all leaks. In complex below-ground details, the full system design should be considered before choosing the sealing method.\u003cbr\u003e\u003c\/p\u003e","brand":"Platinum Building Chemicals Ltd","offers":[{"title":"Pack 100","offer_id":13118337384547,"sku":"BWA21","price":10.5,"currency_code":"GBP","in_stock":true},{"title":"Pack 25","offer_id":13118337417315,"sku":"BWA21-25","price":3.5,"currency_code":"GBP","in_stock":true},{"title":"Pack 50","offer_id":13118337450083,"sku":"BWA21-50","price":6.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/platinum-plaster-plug-sealing-washers-pack-100-waterproof-membrane-ancillaries-918.webp?v=1780826946","url":"https:\/\/www.platinumchemicals.co.uk\/products\/platinum-plaster-plug-sealing-washers-membrane-fixing","provider":"Platinum Chemicals","version":"1.0","type":"link"}
