Description

Watco Dampguard Advanced is a solvent free, penetrative, epoxy resin coating for damp proofing floors and walls in a variety of internal locations. Provides a hard wearing and chemical resistant surface which resists fungal or bacterial growth.

Recommended areas of use

Walls
Ceilings
Floors in hospitals
Kitchens
Food storage areas
Dairies, laundries
Cellars
Inspection pits and tunnels

Features

May be used in confined areas
Microporous to allow moisture vapour to escape from substrate
Can be used on walls or floors
Decorates and damp proofs in one
Virtually odour free

Emulsion paint can be applied to Watco Dampguard Advanced since it is generally permeable to moisture vapour. The Dampguard Advanced surface should be abraded to provide a key. Carpet may be laid over Dampguard Advanced but not bonded down since the adhesive will not allow the substrate to breathe.

Application

Surface preparation

Damp Surfaces - To ensure penetration, the surface should be as dry as possible, clean, sound and free of any loose material. On surfaces subject to hydrostatic pressure, it is essential that all previous coatings and surface weaknesses be removed.

Concrete, Brick and Masonry - Concrete to be treated should preferably be dry and at least four weeks old and free of any soft surface laitance and contaminants. Thoroughly remove all loose material by wire brushing. Very smooth concrete or concrete with soft laitance should be etched with Watco Etch & Clean and the area thoroughly washed off and allowed to dry. Grease or oil should be removed with Watco Bio D and the area thoroughly washed off and allowed to dry. Very porous surfaces may be primed with one coat of Watco Universal Sealer.

Surfaces with Algae or Fungal Growth - Remove all growths by wire brushing. Apply a fungicide to the surface allowing the surface to dry out between applications. Wash the surface thoroughly and allow to become as dry as possible. Failure to remove traces of the fungicide may result in poor adhesion of the Watco Dampguard Advanced.

Painted Surfaces - Remove all defective paint and create a key by rotary wire brushing, sanding etc.

Mixing

Each pack of Watco Dampguard Advanced consists of a container of resin and a larger container of activator. Stir and empty the complete contents of the resin into the activator and continue stirring with a wide bladed tool very thoroughly until an even colour is obtained.

Application

If appearance is critical we recommend the application of a small trial area first.

Best results are obtained in warm conditions with good ventilation (minimum 15°C). Do not apply below 10°C. Apply two liberal coats by pile type roller (not foam). Avoid over rollering.

The second coat should be applied within 24 hours. On high suction backgrounds or very damp surfaces a three coat system is recommended. In areas where the temperature exceeds 320°C and on high suction backgrounds it is advisable to dampen the surface first with water. Do not re-work areas of coating or attempt to even out areas which are starting to cure and showing differences in colour. Any colour differences should disappear when the coating is thoroughly cured.

In exceptional temperature conditions advice should be obtained from Watco’s Technical Department.

Useful information

Dampguard Advanced needs to be applied in two coats. It’s supplied as a tin of resin and a tin of curing agent. And when you mix the contents of the two tins together, it starts a reaction which causes the paint to cure.

If you’re painting an area of 30m², you’ll need four 3L tins (because, once mixed, a tin won't keep for the second coat).

Here’s how we work it out:

Area to be painted: 30m² with two coats (we recommend two coats for the best result)
Tins needed: 4 x 3L
Why: Use 2 x 3L for the first coat; and the same again for the second

Our Coverage Calculator works this out for you – that way you know you’re buying exactly the paint you need and can use, without unnecessary waste.
