Index Common Damp Problems

The lack of adequate waterproofing poses a very real threat to the structural integrity of homes and buildings. Needless to say, it poses a very real threat to their contents as well. Damp homes and buildings also pose a threat to the health of its occupants. It is unsightly and a constant source of annoyance.

The purpose of waterproofing therefore is to protect homes and buildings as well as their contents against the damaging effects of water. Waterproofing can therefore be defined as a material or system that prevents or resists moisture and water seepage through the masonry components of a home or building.

Having a little knowledge of the more common damp problems will help you prevent or remedy them, saving you great expense, time and aggravation.

Rising Damp Rising damp occurs as a result of capillary suction of moisture from the ground into porous masonry building materials such as stone, brick, earth and mortar. It potentially occurs where there is no damp proof course (DPC) or where the DPC has been damaged or bridged. The height to which the moisture will rise is determined by the evaporation rate and the nature of the wall. The normal limit for rising damp generally ranges from 0.5 to 1.5 meters above ground level. Rising damp may show as a stain on wallpaper and other interior finishes, blistering of paint and loss of plaster. Damp walls encourage the growth of mould, which with high humidity can lead to health problems for occupants. Externally, a damp zone may be evident at the base of walls and in extreme situations, with associated fretting and crumbling of the substrate.

Page 6

Falling Damp Falling damp is caused by downward water penetration from the top of porous masonry walls. This could be as a result of the top of a boundary wall (coping) not being adequately waterproofed, failed flashings, blocked or leaking gutters, joints that have lost their mortar and the build-up of dirt and moss on upper surfaces of stone or brickwork. Fallen leaves, bird manure, moss and dirt contain weak acids and salts, which if carried by water into masonry can promote decay.

Penetrating Damp Penetrating damp is a common form of damp. It occurs as a result of the horizontal ingress of water through gaps (sometimes tiny) in a building’s substrate. Penetrating or horizontal damp can be due to leaking water pipes and unprotected plaster or brick. Air-conditioning drips and hot water system overflows can also cause problems. Penetrating damp tends to produce localised patches of dampness and decay, whereas rising damp may affect the base of a whole building.

EfflorescenceEfflorescence is where an appreciable quantity of soluble salts is present in the masonry. It routinely occurs in masonry construction, particularly in brick and typically occurs during the initial curing of the cementitious product. Damp carries these salts up the masonry to where the damp evaporates. As the water evaporates, it leaves the salts behind as a white fluffy deposit. This deposit can normally be brushed off when dry. It usually disappears with time after rains or washing with water. Efflorescence is generally an aesthetic concern and not a structural one. However, where there is excessive efflorescence, the crystallizing salts within the pores of the masonry can disrupt even the strongest material, leading to the fretting and crumbling of the substrate.

Positive Side Waterproofing Positive side waterproofing prevents damp problems at its source whereas negative side waterproofing is a remedial solution only.

Positive side waterproofing is applied to water bearing surfaces of a building or structure – usually to the external walls. Positive side waterproofing is also applied to the walls of showers, bathrooms, kitchens and laundries to prevent moisture penetration into adjoining rooms and cupboards. In these instances, the surfaces are the water bearing side of the wall. Positive side waterproofing protects against, amongst others, corrosive soils which can attack masonry and concrete and even steel reinforcing. Water seepage as a result of a high water table, rain and even garden sprinklers is also prevented. In all new construction, positive side waterproofing must form an integral part of the building specification in order to ensure a problem free structure.

Negative Side Waterproofing The most common use of negative side waterproofing is where access to the outside face is inaccessible or where the source of the problem is impossible or difficult to reach. Examples include pits, shafts, basements, wine cellars, underground parking and retaining walls etc. Shells of ponds and pools are also susceptible to negative water seepage. Negative side waterproofing is generally a testament to poor building practices. Negative side waterproofing materials can also be applied to the positive side of a building. Membrane waterproofing systems are not suitable for negative side waterproofing as the external water pressure (hydrostatic pressure) can easily disbond the membrane from the substrate.

Product Overview

Coprox Masonry Waterproofing

• Preventative & Remedial Waterproofing for Water Bearing Positive & Negative Side Masonry Surfaces

• Waterproof Decorative Coating

• Suitable for Brick, Mortar, Screed and Plaster

Coprox Masonry Waterproofing is an easy and effective masonry waterproofing solution suitable for commercial and domestic applications. It prevents water seepage in new masonry structures and remedies damp problems in existing ones. Its unique properties make it effective for use on water bearing positive side or interior negative side above or below ground level masonry surfaces.

Its universal applications range from the preventing and remedying of rising, falling and penetrating damp to the waterproofing of structural, retaining and boundary walls; floors, showers, basements, wine cellars, underground parking, ponds, swimming pools, reservoirs and water features.

Wherever moisture is present, the crystalline properties of Coprox Masonry Waterproofing migrate into the capillaries and shrinkage cracks of brick, mortar, screed and plaster effectively impeding the progress of moisture in or out of the protected surface. There is no need to wait for damp to dry before treatment commences - the moisture assists in remedying the problem. Coprox Masonry Waterproofing will not allow the passage of water molecules. It will however, allow the passage of air, thus enabling the structure to breathe and dry.

In addition to its waterproofing qualities, Coprox Masonry Waterproofing eliminates the need for plaster and paint, providing an attractive and unique naturally aged, mottled and rustic finish which becomes more pronounced over time. It is available in a wide range of striking colours. Walls are decorated and waterproofed in one application.

Coprox Masonry Waterproofing also serves as an excellent waterproof plaster primer for conventional paint.

Coprox Cobond

Seamless Waterproofing Membrane System for Water Bearing Positive Side Masonry Surfaces (Coprox Cobond mixed with Coprox Masonry Waterproofing)

Suitable Surfaces• Sufficientlyagedandcuredvirginmortar,screed,concreteandcement

or pool plasters of recognised building mix standards • GoodqualityvirgincementandclaybricksIf in any doubt as to surface suitability, do a test area first.

Weather Conditions Do not apply to exterior surfaces if rain is imminent, in humid conditions, during high winds or freezing temperatures.

Surface Preparationa) Ensure the surfaces are free of any negative moisture. Should this not be the case, the

surfaces must first be treated with Coprox Masonry Waterproofing or if necessary, plastered with Coprox Waterproof Cement Additive added to the plaster mix, before proceeding with the application. This applies equally to swimming pools, ponds, reservoirs and water features where high water tables may be present. Surfaces such as boundary and retaining walls must also be treated in this manner before the application commences.

b) Remove any efflorescence whilst dry using a stiff bristle scrubbing brush.c) Where the application is being used for swimming pools, ponds, reservoirs and water features: (i) Remove algae and oils with a scrubbing brush using: • 1partofhydrochloricacidto20partsofwaterfortheentiresurface. • 1partofhydrochloricacidto10partsofwaterforthewaterlineandsteps. (ii) Neutralize the acid washed surfaces with copious amounts of water. (iii) Mop up the neutralized acid wash.d) Remove dust, dirt and all other foreign matter.e) Surfaces must be completely dry and free of any moisture before application commences.

Mixinga) Decant 5 litres* of Coprox Cobond into a clean plastic container and stir thoroughly. b) Sprinkle 5 kg of the desired colour Coprox Masonry Waterproofing slowly into the 5 litres

of Coprox Cobond preferably using a mechanical mixing device until smooth and free of lumps. Use immediately.

c) Stir the solution frequently throughout the application.

First Coata) Apply the first coat to the dry surfaces using a suitable brush. Brush strokes should be

applied in one direction to a thickness not exceeding 1,5 mm. b) Thoroughly cover depressions, fine cracks and pinholes. c) When bridging joints or abutments of slabs and walls, the application should cover the

joint by at least 75 mm on either side.

Second Coat a) Ideally, the second coat should be applied as soon as the first coat is touch dry,

approximately 30 minutes. If the second coat can only be applied later, ensure that the first coat is completely dry and free of any moisture before the second coat is applied.

b) Apply the second coat at right angles to the first coat, again to a thickness not exceeding 1,5 mm.

c) Keep the application protected from rain.d) Allow the application to dry for at least 48 hours before use.

Filling Swimming Pools, Ponds, Reservoirs and Water FeaturesTo minimize foaming when filling swimming pools, ponds, reservoirs and water features for the first time:a) Thoroughly hose down the surfaces several times with generous amounts of water 48

hours or more after the application has been completed. b) Mop up the foamy water.c) Proceed with the filling of clean water. Should any foam still be present after filling, the foam will dissipate with filtering or with changes of clean water.

ToxicityOnce dry, the application is non-toxic and therefore not harmful to human, animal or plant life. However, the water must be free of any foam and allowed to age sufficiently and treated chemically before introducing fish or plants. Consult your local pet shop or water authority in this regard. In the case of swimming pools, pH levels should be properly maintained. All chemicals should be added via the weir.

Bonding & Keying Agent For the better adhesion of plaster, screed or when using Coprox Waterproof Dualcoat as a trowel-on application, liberally brush Coprox Cobond onto the wall or floor surfaces and apply the plaster, screed or Coprox Waterproof Dualcoat to the surfaces while the Coprox Cobond is still tacky.

Additive To Coprox Waterproof Dualcoat To minimize crazing & cracking when Coprox Waterproof Dualcoat is used as a trowel-on application, substitute 1 litre of the water content with 1 litre of Coprox Cobond when mixing the Coprox Waterproof Dualcoat (see Coprox Waterproof Dualcoat instructions on page 21).

Cleaning Tools & EquipmentAll tools should be cleaned with water immediately after use. If not cleaned immediately, solvents such as benzene or paint thinners can be useful in removing the hardened product. Product and waste water containing product should not be discharged directly into drains and waterways.

Coprox Masonry Waterproofing & Coprox Waterproof Dualcoat

Coprox Masonry Waterproofing is brush applied, whereas Coprox Waterproof Dualcoat can be either brush applied as a textured finish or trowel applied as a skim coat finish. The trowel-on application instructions are described on page 21.

Surface PreparationWhen the products are used for decorative purposes, they are still applied in exactly the same manner as a waterproofing application as described on pages 18 and 20. For aesthetic purposes however, additional attention must be given to the surface preparation when using Coprox Waterproof Dualcoat. Where unpainted and painted surfaces adjoin each other, the unpainted surfaces should first be painted the same colour as the painted surfaces before application commences in order to minimize colour variations of the completed application. When used on dry wall partitioning, the joints should first be covered with jointing tape and then the entire surface primed with a suitable oil based primer.

ApplicationWhen using Coprox Masonry Waterproofing or Coprox Waterproof Dualcoat, the application should only start once all building or renovation work has been completed, as cement coatings cannot be easily touched-up once dry without leaving noticeable patch marks.

An entire wall from corner to corner should be completed without interruption. Cutting around window and door frames, light fittings and cornices etc. must be done as and when they are encountered and not prior to application.

Work in manageable sections. Do not allow previous sections to dry before continuing with subsequent sections - overlap marks will be noticeable if wet and dry edges of sections overlap each other. Work section by section and complete the entire surface area without interruption.

On high walls or large surface areas, one applicator should apply from the top down while another applies from the bottom up, or one applicator applies from the left side and another from the right.

Where a second coat is desired, the same colour must be used for both the first and second coat. The second coat may appear lighter than the first coat.

When being used in bathrooms, showers and kitchens the application should be sealed with Coprox Wall & Floor Clear Sealer to prevent staining.

Changing the Colour of an existing Coprox Masonry Waterproofing or Coprox Waterproof Dualcoat application

Surface Preparationa) Ensure your existing application has been allowed to properly cure for at least 24

hours and is dry before proceeding to change its colour.b) Remove dust, dirt and all foreign matter.

Mixinga) Pour 5 litres of clean water into a clean plastic container.b) Mix 50 ml of Cobond with the 5 litres of clean water and stir thoroughly.c) Sprinkle 5 kg of the desired colour Coprox Masonry Waterproofing slowly into the
