Dryzone Hi-Lime Renovation Plaster contains a higher proportion of natural hydraulic lime and calcite, making it appropriate for use in traditional and heritage buildings. The high breathability of the plaster makes for a quick-drying application and ensure moisture vapour flow through the wall is not impeded.
Replaster after rising damp treatment, with Dryzone Damp-Proofing Cream or Dryrod Damp-Proofing Rods, in traditional or heritage buildings.
Dryzone Hi-Lime Renovation Plaster is an environmentally-friendly alternative to hard cement render. Its porous structure allows moisture to evaporate from walls to achieve a dry decorative surface.
Remove all skirtings and architraves which cover any contaminated plaster. Remove all damp and/or salt contaminated plaster to a height no less than 300 mm above the maximum level of visual rising damp.
Remove any timber fixing grounds that are present in the masonry, then proceed with the application of Dryzone Damp-Proofing Cream or Dryrod Damp-Proofing Rods as per normal.
Dryzone Hi-Lime Renovation Plaster should be mixed with a drill mixer. Pour 5.5 litres of water into a container, then slowly add all the plaster to the mix. Start mixing the product at a low speed to minimise dust generation. As the paste begins to form, the mixing speed may be increased. Mixing should take around 3-4 minutes until smooth.
For particularly high suction or dry backgrounds, first wet down the surface using clean water. Do not use other additives such as PVA. Dryzone renovation plasters are applied in two layers. The first layer is a rough coat of 5 - 10 mm thickness. This will act as an anchoring layer for the second layer, which should not be applied until the rough coat has become sufficiently firm.
Apply the second layer of Dryzone Hi-Lime Renovation Plaster to a minimum thickness of 15 mm. For more specific application instructions, please refer to the product datasheet.
Level the plaster with a simple straight edge or adjusters to maintain the thickness without using excessive pressure on the product.
Dryzone Hi-Lime Plaster can be left as a decorative finish. Any other finishing (e.g. application of a skim coat) is carried out once the curing process is complete, after at least 14 days. Dryzone Mould-Resistant Emulsion Paint can also be used as a finish.
1. | Thinner thicknesses may be used (e.g. when matching in with existing plasterwork) but maximum moisture salt resistance is achieved when the total plaster thickness is at least 20 mm (2 layers) |
Easy to use. Does what it is supposed to do.
After deciding to try this product I was not able to find a supplier in the local area but Safeguard Europe delivered it free and rapidly. The product comes with clear instructions and is easy for a DIY person to use. The plaster was easy enough to apply to the wall and I am happy with the result but as I have only just done the job I can’t comment on its effectiveness of stopping damp.
I had a serious problem with damp in three flats following a long term water leak. After drying out the timer was treated and the walls hacked off. The plaster system went on well and I finished it to a good standard. All signs and smells of damp have gone and recommend the products.
