Soluguard Multi-Surface Biocide

SoluGuard Multi-Surface Biocide (HSE No. 9517)

SoluGuard Multi-Surface Biocide is a high-strength biocide for removing algae, fungi, moulds and moss growth from a wide range of surfaces. It is supplied ready-for-use in a 5 litre pack.

Surfaces that can be treated include internal walls, roof tiles, concrete surfaces, brick, stone, render and plastic. SoluGuard Multi-Surface Biocide is also suitable for removing algae and moss from driveways, patios and ornamental stone monuments. To greatly minimise regrowth SoluGuard Multi-Surface Biocide can be used prior to treatment with Stormdry Masonry Protection Cream. This will clear existing biological growth from masonry surfaces and also greatly minimise future growth of algae, moss, lichens and moulds that require a damp surface in order to flourish.

Product benefits of SoluGuard Multi-Surface Biocide include:

Each 5 litre pack of SoluGuard Multi-Surface Biocide will treat 10 m2 – 100 m2, depending upon the porosity of the substrate being treated. It can be applied with a brush, roller or by coarse spray. For best results the treated surface should be cleaned of dead growth after 72 hours or more have passed, using clean water and a pressure washer.

SoluGuard Multi-Surface Biocide Application

  1. Remove surface laitance with a masonry brush
    Remove any loose mortar, dust or other surface laitance using a masonry brush. When used on exterior surfaces, SoluGuard Multi-Surface Biocide should be applied in dry weather - ideally when no rain is forecast for the next 24 hours.
  2. SoluGuard Multi-Surface Biocide spray application
    Apply SoluGuard Multi-Surface Biocide in accordance with the application instructions [1]. For best results, the treated surface should be cleaned after 72 hours using clean water. This will remove deposits of dead biological growth from the treated surface.
  3. Before and after application of SoluGuard Multi-Surface Biocide
    For best results, the treated surface should be cleaned after 72 hours using clean water. Where appropriate a pressure washer can be used. This will remove deposits of dead biological growth from the treated surface.
