DIY Rising Damp Kit


Our DIY Rising Damp Kit provides you with everything you need to combat Rising Damp. You don't need any specialist skills or equipment to undertake this simple task.



Installation of this Damp Proof Course requires drilling of a series of 12mm holes into the mortar bed of your property into which DampOut+ Damp Proof Cream is injected. The Damp Proof Cream diffuses and waterproofs the pores in the masonary blocking the route of rising damp. Our How to Install Damp Proof Cream document provides simple step by step instructions for successful installation of the damp proof course and is included in the DIY Rising Damp Kit.

The DIY Rising Damp Kit Contains:

  • Applicator gun.
  • 10 x DampOut+ Damp Proof Cream (400ml).
  • Ultimate Pro Integral Waterproofer Premium Water-Proofing Additive (5L).
  • PVC Gloves.
  • 2 Certified Armeg Drill Bits (12 x 300mm and 12 x 160mm).
  • Safety Goggles. 
  • Instruction Leaflet.
  • Health and Safety Leaflet.

The Armeg drill bits are the correct diameter for damp proof course installation, and will no doubt become a staple item in your toolbox that can be used again and again.

Relevant Information:


Rising Damp:

Rising Damp is the common term for the drawing up of water from the ground vertically through a permeable wall structure. The water rises through the pores in the masonry.

In order to combat rising damp, more modern buildings often have impermeable membranes installed during construction which prevent the upward movement of water through the walls. However, such impermeable membranes can fail as a result of age, chemical breakdown of the damp proof course, bridging or movement in the walls to name a few. Older buildings are unlikely to have had a damp proof course installed, leaving them vulnerable to Rising Damp. 

Does your property suffer from Rising Damp?

Rising Damp can generally be identified by the very definite tide mark or damp line which can be seen on the internal surface of the wall, together with the use of a Damp Detector (Product Code: N03800). If you property is suffering from rising damp, the moisture reading taken above the damp line or tide mark will be considerably lower than the readings taken below the damp line or tide mark.

Semi-soluble salt and mineral deposits can often be found on the surface of the wall. These are drawn up with the rising water molecules and are deposited on the wall when the rising damp evaporates from the surface. Also, please be aware that rising damp may result in moisture in timber skirtings if they come into direct contact with the wall. This can be tested using a Wood Moisture Meter (Product Code: N03120).

Rising Damp Treatment:

Rising Damp can be treated by using Chemical Damp Proofing Creams. These products can be used to install or reinstate a barrier to stop the Rising Damp through the walls of your building.

Damp Proof Creams are installed by injection into holes drilled into the mortar course of buildings suffering from rising damp. Once the the Damp Proof Cream is installed, active constituents in the Damp Proof Cream disperse through the mortar spreading a waterproof resin that prevents a barrier to rising water.


If the Rising Damp resulted in salt or mineral deposits on the plaster of your walls, it will be necessary to replace the contaminated plaster. If not replaced, the salts in the plaster will absorb moisture from the air resulting in the appearance of damp, independent of structural dampness. When re-plastering, it is important to use an integral waterproofing additive. A suitable product is included in our DIY Rising Damp Kit (Product Code: N00081) or can be found separately by clicking here.

Preparation for the Damp Proof Cream:

1. Repair or install drains to carry away surface water.

2. If internal floors are below external ground level form trenches along the external face of the walls at least 150mm below the proposed Damp Proof Course level (where foundation depth allows). If approach is not feasible the Damp Proof Course must be placed 150mm above external ground level and the internal walls tanked below the damp proof course to prevent lateral migration of moisture/salts.

3. Remove skirtings, fixings and render/plaster to expose the line of the proposed Damp Proof Course (mortar bed).

4.Internal plaster which may be contaminated with hygroscopic salts should be ‘cut back’ a minimum of 1m above the Damp Proof Course line or 300mm above the highest signs of dampness/salts.

5.Check flooring timbers for signs of fungal decay and repair/replace as appropriate.

6. Ensure wall cavities are cleared of debris.

Application of the Damp Proof Cream:

7. Walls vary in thickness and type of construction so it is essential these factors are taken into account before deciding on an appropriate drilling pattern.

8. Older properties may consist of several different styles of construction and the specification of drilling and injection should be carried out accordingly.

9. Damp Proof Course height should always be at least 150mm above the external ground level.

10. Vertical Damp Proof Courses should be provided to connect horizontal Damp Proof Courses where ground levels change and to isolate untreated wall areas (adjoining properties, garden walls etc.)

11. In most cases solid brick walls may be drilled/injected from one side only.

12. For cavity walls each leaf may be dealt with as separate 155mm thick wall. Alternatively, if preferred, drill through the selected mortar course, across the cavity, then drill the other leaf of brickwork to a depth of 90-100mm and inject in one continuous process (the physical properties of the Damp Proof Course ensure the Damp Proof Cream remains in contact with the surrounding mortar bed).

13. Always ensure the cavity is clear before treatment.

14. In random stone and rubble infill walls, as far as practically possible, follow the mortar course at the appropriate level. However, if the stone is of a porous type, it may be possible to vary the drilling location (mortar/stone) as long as the mortar bed perpends are treated 

15. In the walls of greater than 350mm thickness it is recommended that drilling is undertaken from both sides at corresponding height.

16. In the case of drill holes becoming blocked these should be re-drilled just prior to injection or a new hole drilled nearby to ensure than an adequate volume of Damp Proof Cream is introduced

17. Drill 12mm diameter holes horizontally in the mortar bed at centres no greater than 120mm. The depth of hole required for various sizes of wall is shown in the table. For walls of intermediate thickness the depth of holes should be pro rata. Where the masonry is irregular, ensure the horizontal drilling pattern targets the base of all perpends of the course selected. 

Injecting the Damp Proof Cream:

18. If wall is dry you MUST pre-treat the wall with water. A couple of hours before application fill the holes with water.

19. To inject the Damp Proof Cream use either a caulking gun or hand pump.

20. Use the gun/pump to establish a positive pressure. Insert the lance of the Damp Proof Cream application gun into the full depth of the pre-drilled hole. Squeeze the gun trigger and back fill each hole fully with Damp Proof Cream to within one centimetre of the surface. When treating cavity walls from one side make certain that the holes in each leaf are filled.

Finishing the Job:

21.On external faces of walls drill holes can be re-pointed using a matched mortar or plugged with plastic caps of a suitable size and colour.

22. On internal faces holes can be left open and plaster stopped short of the Damp Proof Course or covered with skirting boards.


23. The removal and replacement of internal salt contaminated plaster is an important part of effective damp proofing work (salts left by rising damp are hygroscopic and cause future staining independent of structural dampness). It is essential, therefore, to follow specific guidelines drawn up for dealing with the particular challenges posed by damp/salt affected surfaces. It is advisable to leave walls injected with Damp Proof Cream to dry for as long as possible, and for at least 14 days, before removing excess salts and commencing re-plastering.

24. An Integral Waterproofing Additive should form part of the re-plastering specification.
