We recommend the installation of Dryzone Damp Proofing Cream at a maximum temperature of 35°.
Thick, white cream
Silane and Siloxane
5 litre plastic bucket, 600 ml foil sausage and 310 ml mastic cartridge
Dryzone eliminates rising damp in masonry walls.
The patented and BBA approved cream is simply injected into holes drilled along a horizontal mortar course.
Once cured, the high-performance active ingredient will provide a dampness barrier, making that mortar course into a new damp-proof course.
Powerful water-repellent barrier
Outperforms competing creams in laboratory testing — Up to 4x stronger
Easy to apply, no pressure pumps or solvent-based chemicals required
BBA Approved — at least 20 years protection
Suitable for use in very damp walls
The World’s most extensively tested damp-proofing cream
High-strength formula with 80% active ingredient
Accredited for up to 95% wall humidity
Compatible with Dryzone System replastering specifications
Dryzone is the most rigorously tested and accredited damp-proofing cream on the market. It has been tested by numerous national and international testing houses:
Laboratory and field testing has also shown that Dryzone outperforms creams by competing manufacturers in walls with either low or high levels of moisture saturation.
The cream comes in both 310 ml mastic cartridges, for isolated areas of damp, or 600 ml foil-wrapped sausages, for large or multiple jobs using the Dryzone Applicator Gun. No special powered pumps or solvent-based chemicals are required.
There is also a range of Dryzone System Tools to help application go smoothly, including the Dryzone Drillbit and Dryzone Hole Clearing Tool.
Dryzone Damp-Proofing Cream is part of the Dryzone System for renovating internal walls suffering from rising damp. This means that it is fully compatible with both Dryzone Renovation Plasters and Dryzone Express Replastering. Full guidance to the use of Dryzone Damp-Proofing Cream and the full system is available in the form of our guidebook, Rising Damp and its Control.

Mark your drill bit to the appropriate depth for the wall you wish to treat. A Dryzone 12 mm Drill Bit is recommended for enhanced debris removal.
Set your SDS drill to rotary hammer mode and attach the suitably marked drill bit. Identify the lowest horizontal mortar course that is accessible and continuous and at least 150 mm above the outside ground level. Drill holes to the full recommended depth, at regular 120 mm intervals along the wall. As the drill bit approaches the final 40 mm of the intended hole depth, make sure to reduce the pressure to avoid damage to the far side of the wall.
Clear the debris from all the holes using the Dryzone Hole-Clearing Tool. Revisit each hole a few times to ensure they are as clear as possible. Then sweep the area clean of debris and dust.
310 ml: Remove the sealed tip of the cartridge using the Dryzone® Rod Cutter or sharp cutter. 600 ml: Insert a 600 ml sausage into the aluminium barrel of the applicator gun.
310 ml: Pull the plunger all the way back and insert the cartridge. Push the plunger back to lock in the cartridge. Screw on the blue nozzle and fit the clear delivery tube. 600 ml: Pierce the plastic casing of the sausage with a sharp knife to release the cream. Screw the nozzle assembly securely onto the aluminium barrel.
310 ml: Pull the trigger a few more times until the cream appears in the clear delivery tube. 600 ml: Pull the trigger a few times until the cream appears from the opening of the metal delivery tube.
Insert delivery tube of the applicator to the full depth of the pre-drilled hole. Squeeze the gun trigger and back-fill each hole fully with Dryzone Cream to within one centimetre of the hole opening.

Once Dryzone is installed, it diffuses before curing to form a water-repellent resin. This prevents the damp from rising up the wall.

We recommend the installation of Dryzone Damp Proofing Cream at a maximum temperature of 35°.
What is the minimum temperature that I can install Dryzone Damp Proofing Cream?
Dryzone Damp Proofing Cream should be installed at a minimum temperature of 5° and rising.
Do not create a chemical DPC using Dryzone Damp Proofing Cream if the temperature is due to drop below 5° in the next 5 to 7 days.
Do not install Dryzone Damp Proofing Cream in wet frozen walls, as this can affect the composition and dissipation of Dryzone DPC Cream’s active chemicals.
Can Dryzone Damp Proofing Cream be used in old and new concrete?
The alkalinity in concrete can cause an initial faster reaction time in Dryzone DPC Cream, which can reduce the spread rate.
New concrete tends to have a higher rate of alkalinity.
Old concrete tends to be less alkaline due to the carbonation process.
As we cannot exactly predict the alkalinity in a given section of concrete, we suggest that drilling and injection should be carried out with 100mm centres in all concrete.
