Recommended Uses

Guard BT is used for water-proofing substrates including brick, stone, timber, concrete, metal and steel.

Drying and Curing Time

    • Touch Dry: 40 minutes

    • Hard Dry: 3-4 hours

    • Full Cure: 24 hours

    • Re-coatable: 2 hours

Drying times are based on temperatures of 20°C, lower temperatures will increase drying times. Please speak with our technical team before elevating temperatures or attempting to force cure any of our products unless already stated. Shop conditions such as having good airflow will optimise curing.



Bitumen products are not generally used as part of a system. If top coated the bitumen will likely bleed through.


Surface Preparation

    • Ensure surfaces are clean, dry and free from grease and other contamination before coating.

    • Thoroughly degrease and where applicable, abrade to remove rust and promote good adhesion of the coating. For optimum corrosion protection, mild steel should be blast cleaned to Sa2.5.

    • Complex structures may be more effectively cleaned by HPWJ (high pressure water jetting).

    • Minimal preparation is required compared to most coatings. Ensure surface is free from rust and contaminates then suitable abraded to give a key. See cleaning information.


Guard Solvent F



Guard Solvent F

Once painting has been completed, clean all equipment with above mentioned cleaning solvent. Spray equipment should be appropriately flushed through for 3-5 minutes (returning unused paint to the tin, unless thinned which should be stored in a separate tin) before replacing any used solvent with clean solvent to leave in the pump, gun and lines.

If over coating with itself, ensure surface is thoroughly cleaned and previous coating suitably abraded.

Safety Precautions

To avoid the risk of spillage always store and transport in an upright secure position. Materials are hazardous and can also be flammable therefore appropriate precautionary measures must be taken including the use of gloves, glasses and recommended P.P.E in accordance with the material safety data sheets (MSDS).
