(5kg) Rempro White Damp Proof Paint Description

Rempro Damp Proofing DPM Paint White

Membrane damp barrier paint for walls & floors

Rempro Damp Proofing paint can be used for several applications, including damp walls, floors, and basement walls (internally and externally). This damp proof paint can be used as a primary waterproofing barrier on new build basement before installing Ultra GEO membrane and land drain, respectively.

It contains styrene-butadiene rubber (SBR), giving excellent waterproofing properties.

• Water-based compounds that can be applied even to damp backgrounds
• Quick-drying. Typically dry in 1 hour.
• Non-toxic, non-hazardous, solvent and plasticiser free
• Good bond too many substrates
• Low water vapour permeability
• Toughness, high flexibility, extensibility and good crack-bridging properties.
• Alkali resistant. It can be applied to alkaline surfaces.
• Resistant to silage acids
• Non-staining and stain blocking
• Brush or roller applied in two coats.

Uses include:

1. Basements: As part of a waterproofing system.
2. Floors: Under/above screeds to provide a damp proof membrane.
3. Ponds: Can be used for aquatic life in ponds as a waterproofing lining.
4. Walls: Can be used under render.
5. Water storage: The membrane performs well even when continuously immersed in water. 
6. Gas barrier: To minimise methane/radon transmission. 
7. Tiling: As secondary protection under tiles in wet areas, e.g. bathrooms, food processing areas, balconies, etc.
8. Silage storage: Protects concrete from silage attack.

Coverage

A minimum dried coating thickness of 0.6mm is necessary to provide a vapour barrier. This should be applied in a minimum of two coats. (i.e. 0.3mnn dry film thickness per coat for two applications) For the final dried membrane thickness to be 0.6mm, a coverage rate of 1.20kg/m2 is required (this is the total for all coats).

This corresponds to approximately 1 litre/m2.

The colour of the damp proof paint will differ slightly from the colour of the dried membrane. The colour shade may vary from batch to batch. The membrane dries to form a tough semi-gloss finish.

Application

The background surface should be smooth or have an even texture. Any masonry should be flush pointed, and defects in existing surfaces made good. The surface needs to be clean, sound and free from dust, loose material or free surface water.

The membrane should not be applied in wet conditions or where these conditions are likely to occur before the membrane has dried. The membrane should not be applied when the background temperature or the air temperature is below 7°c.

It is sometimes advantageous to pre-wet concrete or masonry backgrounds, so these are damp but free from any water glistening on the surface. Because of the wide variety of background types and site conditions, it is always advisable to check adhesion to the background by testing on a sample area before starting any job.

The membrane may be applied by brush, roller or airless spray. If necessary, the compound can be diluted with water up to 10% water; however, care should be taken to ensure that the correct dry coat thickness is applied. If two coats are being applied, it is recommended that the coats be applied at right angles to each other.

Before applying the second coat, it is necessary to let the first coat become touch dry. The time required to reach this touch dry condition will vary according to site conditions but will typically be in the order of 1 hour. It is preferable if the second coat is applied within 24 hours of applying the first.

After all, coats have been applied; the membrane should be left for at least 4 days before attempting any ponding tests. Under unfavourable drying conditions, this period may need to be extended.
