Parchem Fosroc Nitoproof 210

High performance water based rubberised bitumen waterproofing membrane with root inhibitor

$16-18/m² (2 coats)

Coverage: 1.5 L/m² (2 coats)

Nitoproof 210 is a high performance single component water based bituminous rubberised waterproofing membrane with root inhibitor ideal garden beds, planter boxes, retaining walls, basements and building foundations.
  • Overview

    Why we like it:  Nitoproof 210 is a cost-effective solution for small planter boxes and below ground areas with the added advantage of root inhibitor. It is easy and quick to install: self-priming (on porous substrates) and can be recoated in 4 hours.

    Bond breaker: Fosroc Nitoband Tape System
    Primer (concrete & masonry): Fosroc Nitoproof 210 diluted 1:1 (by volume) with water.
    Primer (metals & plastics): Fosroc Nitoprime 115
    1st coat: Fosroc Nitoproof 210 (0.75 mm WFT) (4 hours drying time @ 23 degrees Celsius until 2nd coat)
    2nd coat: Fosroc Nitoproof 210 (0.75 mm WFT) (3 days drying time @ 23 degrees Celsius until backfilling)
    Protection Board: Proofex Protection Board PP or Proofex Sheetdrain 81

    Drying Times


    Nitoproof 210 shall be diluted at 1:1 by volume with water as a primer on porous substrates. Apply 1 coat of primer achieving a coverage between 0.4 - 0.8L/m2 depending on the porosity and condition of the substrate.

    Then Nitoproof 210 should be applied in a 2 coat application achieving a minimum coverage of 1.5 L/m2 (total) for general waterproofing applications. For heavier sealing properties, total coverage can be increased to 2 L/m2 with subsequent coats. Approximate total coverage: 1.5 - 2L/m2 on primed surface.

    Minimum Wet film thickness per coat: 0.75mm (750 microns)

    Total Dry film thickness: 1 - 1.3 mm



    Substrates must be primed, prior to the application of Nitoproof 210.

    Nitoproof 210 is self-priming on most porous surfaces. Dilute Nitoproof 210 1:1 by volume with water, stir until homogeneous and then apply using a brush or a roller. Always add water to Nitoproof 210 and do not dilute more than 1:1.

    For non-porous substrates, such as metals and plastics, Nitoprime 115 may be selected (see Nitoprime 115 technical data sheet for further details)

    Damp surfaces - entrapped moisture

    Seek technical advice from Parchem.


    Cracks larger than 2mm or structural shrinkage cracks must be firstly filled with a flexible polyurethane type sealant such as Nitoseal PU250 or Nitoseal PU400 and then a 50mm wide polyethylene tape placed over the crack prior to the application of Nitoproof 210. Alternatively the cracks can simply be covered with the Nitoband Tape system. See Nitoband system technical data sheet.

    Fillets and small repairs

    Nitoproof 210 mixed with sand and cement can be used to create corner fillets and repair small voids/minor damage to concrete before membrane is applied. Mix equal parts of fine clean sand and cement, dampen with water then mix in Nitoproof 210 until a smooth paste is achieved. Apply this paste to primed concrete; allow to stiffen before applying the Nitoproof 210 membrane.

    Nitoband Tape, Corners and Detailing Accessories

    The Nitoband Tape System has been specifically developed by Parchem as a superior bond breaker system to traditional sealants and bond breaker tapes. The Nitoband System includes tape (for change of direction – such as wall/wall and wall/floor joints etc.), both 270o external and 90o internal corners, an adjustable internal corner as well as three (3) size variations on pipe detailing squares (suitable from 6mm to 150mm pipe diameters). If being used in tanking and waterproofing applications, the Nitoproof 210 requires a suitable bond breaker at all substrate junctions. Parchem nominates the Nitoband Tape System which includes tape, corners and pipe penetration detailing squares or equivalent bond breaking methods compliant with local waterproofing standards and building recommendations.


    Nitoproof 210 membrane should be lightly stirred before using.

    Membrane Application

    Ensure the surface has been appropriately prepared in accordance with this product data sheet.

    Nitoproof 210 may be applied with a roller (12 mm nap recommended), brush or standard airless sprayer (piston pump unit, 21 - 25 thou tip size) - thoroughly mix product before spraying. Its smooth texture and non-sag formulation makes it suitable for vertical and horizontal application.

    The Nitoband System should be installed first. Apply the mixed Nitoproof 210 across the substrate joins extending approximately 70mm either side of the join.

    Whilst the Nitoproof 210 is still in a wet state install the Nitoband Tape / corners and accessories ensuring that all air voids are expelled. Nitoband Joint corners should be placed in first followed by the Nitoband Tape.

    The Nitoband Tape, corners and pipe detailing squares can be joined via a 50mm overlap, sandwiching a small amount Nitoproof 210 liquid membrane between the overlapping faces. Each successive coat should be applied at 90 degrees to the previous coat.

    Nitoproof 210 is laid onto the surface continually in one direction; maintain wet film thickness. Brooms, brushes etc. should be regularly washed during the operation and at any breaks as follows: Keep available a container filled with sufficient strong detergent / water solution to fully cover the broom or brush. Soak the brush in the solution and shake out before use. As work progresses, rinse the brush at frequent intervals to prevent it clogging, and again shake out before resuming. During any breaks in work the brushes should be left to soak in this solution.

    Allowing a drying time of 4 hours between coats.

    Conduct a final inspection on the surface of the membrane prior to commencing back-filling to ensure no pinholes exist. A further coat may be required if imperfections or pinholes are present in the membrane.


    Nitoproof 210 may be recoated 4 hours after previous coat has been allowed to dry.

    Shorter times may be acceptable in good drying times.

    Key joints and dowel bars

    Nitoproof 210 is suitable as a coating on key joints and dowel bars. Provided the Nitoproof 210 is allowed to dry prior to pouring the next section of concrete, it forms an effective slip layer and so allows relative movement between sections.


    Where the membrane is to be back filled, such as with basement applications, Nitoproof 210 should be protected from mechanical damage with Proofex Protection Board PP or Proofex Sheetdrain 81 drainage/protection system also available from Parchem.


    Splashes of Nitoproof 210 on paintwork etc. should be wiped off immediately using a cloth dampened with water and a strong detergent solution. Brushes and brooms etc. should be soaked in a strong detergent solution immediately after application has finished. Hands and skin may be cleaned using a proprietary waterless hand cleaner, but prevention of soiling is better practice by wearing gloves and overalls.

    Where Nitoproof 210 has been allowed to dry on equipment or surfaces it may be removed using either Fosroc Solvent 10 or mechanical means.
