Product: Thompson's Water Seal Ultra

Surface Preparation and Application:

Thompson's Water Seal Ultra is recommended for use on all types of exterior brickwork and stone, which is above ground level and free from cracks exceeding 0.15 mm width.

APPLICATION PROCEDURE:

Thompson's Water Seal Ultra should be applied to clean surfaces which are free from moulds, fun- gal coatings and all other coatings which may interfere with the penetration of Thompson's Water Seal Ultra. Remove moulds and fungal growths by brushing with a stiff bristle brush. Eradicate any fungal or mould growth by treating affected areas with dilute household bleach solution (1 part bleach to 4 parts water) preferable applied in dry weather. Leave for 48 hours and rinse area thoroughly with water, and allow to dry.

Thompson's Water Seal Ultra is not recommended for use over painted areas. Carry out any repairs and fill any surface cracks prior to treatment. Thompson's Water Seal Ultra can be applied to dry and damp (but not saturated) areas. Ensure that the whole wall is treated, not just isolated areas. Application Shake the can vigorously before use. Apply using brush or roller in one continuous operation. On vertical surfaces, working from the bottom up, divide the area into approximately 1 metre sections. Each section should then be fully saturated. Best results are achieved by brushing/rolling in all directions, paying particular attention to mortar lines. Rework the section to ensure complete saturation. Finish each section before moving onto the next. On horizontal surfaces saturate well. After 15 minutes remove puddles by redistributing to dry areas. Use at full strength. Do not dilute.
