For dealing with MOULD GROWTH on walls, ceilings, window reveals, window frames, skirting boards, doors, etc.

STAGE 1: Use the RLT BACTDET 05 to kill and remove surface mould before preparation work.

Areas to be treated: Treat the whole area where mould can be seen. Extend the treatment one metre (3ft) beyond the infected area in all directions on the walls or ceilings. Carpets should be lifted, especially fitted carpets and the flooring cleaned using the RLT BACTDET 05 Solution.

Directions: Put 1 measure, by volume, of RLT BACTDET 05 into 4 measures, by volume, of warm water. Take a brush or clean cloth and wash off the mould.

When the solution becomes dirty, make up a fresh one. If the cloth becomes dirty, throw away and use a clean one.

Wallpaper surfaces must be washed prior to stripping. After wallpaper has been removed wash infected area again. All wallpaper removed should be bagged, sealed and taken from the premises immediately. Allow surface to dry before proceeding.

PREPARATION: Prepare surfaces, scrape off all loose or flaking paint and rub down. Previously painted surfaces must be etched using sandpaper or similar, before proceeding to Stage 2.

STAGE 2: Use the RLT HALOPHEN to sterilise and protect the surface.

Areas to be treated: Treat all areas of wall and ceiling surfaces where
RLT BACTDET 05 has been used.

Directions: Add 1 measure of RLT HALOPHEN to 4 measures of water, both by volume. When surfaces are dry, brush RLT HALOPHEN Solution well into the surface. If the mould was very bad apply a second coat. Allow surface to dry before decorating.

STAGE 3: MGC FUNGICIDAL ADDITIVES are specially formulated to protect the decoration from mould attack. They can be incorporated into Emulsion Paint, Primers, Undercoats and Gloss Paint, plus Wallpaper Paste, Size, Textured Paints and Grout.

Directions: Add the contents of one MGC FUNGICIDAL ADDITIVE to each 2½ litres of Emulsion Paint, Wallpaper Paste or Size.
Add the contents of one MGC FUNGICIDAL ADDITIVE to each 5 litres of Primer, Undercoat or Gloss Finish.
Thoroughly stir materials after adding contents of MGC FUNGICIDAL ADDITIVE.
Alternatively use BIOCHECK EMULSION - available in Matt or Silk Finish - on walls and ceilings and BIOCHECK WATER-BASED GLOSS on woodwork, metalwork, etc., the decorative finishes specially formulated to resist mould. Full details on both these products are available on request.

STAGE4: Use RLT CLEARMOULD SPRAY to treat Furniture, Textiles and Leathergoods.
WARDROBES AND OTHER FURNITURE - spray RLT CLEARMOULD SPRAY in wardrobes, cupboards and drawers, paying particular attention to corners and shelves. Wipe all areas with a clean damp cloth.
LARDERS - remove all food and treat as for wardrobes.
TEXTILES, CARPETS AND UPHOLSTERY - vacuum articles to be treated. Spray all areas thoroughly with RLT CLEARMOULD SPRAY. Treat both sides of carpets and the floor under carpets.
