HydroFix 10kg damp-proofing plaster + DampStop 5L concentrated injection + application equipment in a single pack. The most practical option for first-time applicators. All equipment included — start right away.
DampStop is an injection-based waterproofing solution applied to stop rising damp and moisture in buildings. The guide below covers every step required to prepare and apply the system correctly.
The following equipment and materials should be at hand for a successful application. The kit already includes an injection gun, a funnel, a measuring jug and a 14 mm drill bit.
Warning: Injection carried out without removing the screed concrete or skirting board prevents the material from reaching the required level and from fully stopping the damp from rising.
The application sequence is critical, especially on walls built with hollow brick:
Note: If injection is done without scraping off the plaster, the brick cavities will open during scraping, so the material may seep out and the application will fail.
Important: The mix must be prepared in a clean plastic container, stirred until homogeneous and used immediately afterwards.
Consumption is calculated based on wall thickness and length in metres. The 5 litres of concentrate in this Complete Kit yield 50 litres of ready-to-use injection solution. Example consumption values (10 cm hole spacing and a wall of standard density):
On low-absorbency substrates such as aerated concrete and solid concrete, the material should be applied in several passes until saturation is reached. This Kit contains 5L of concentrate.
1 litre of DampStop concentrate + 9 litres of clean water = 10 litres of ready-to-use injection material. The 5L of concentrate in this kit gives 50L of solution.
After application, the injection material inside the wall should be left for at least 48 hours.
Yes. If the wall is not coated with HydroFix damp-proofing plaster after injection, complete drying and insulation cannot be achieved. This kit already includes 10 kg of HydroFix + 100 ml of liquid additive.
Yes, the kit contains all the equipment (funnel, measuring jug, drill bit) that makes DIY application possible. For professional applications, controlled injection with a low-pressure pump is recommended.
On internal walls facing external walls, the screed concrete should be chased out to a width of about 10–15 cm so the application reaches down to the main concrete floor. On internal partition walls, removing only the skirting board is sufficient.
It is enough to inject roughly 30–35 metres of a 10 cm wall or 20–25 metres of a 15 cm wall. The HydroFix is enough to coat 4.5–5 m² in a single coat or 2–2.5 m² in two coats.
