System For The Treatment Of Rising Dampness
Summary of application
Step 1: Remove paint from the plastered surface.
Step 2: Application of Damp Seal.
Step3: Repaint / Finishing of the surface.
Detailed description
Rising dampness is a common problem. There are usually requirements from projects that minimum amount of breakage and work need to be done when it come to such issues, A Simple solution with minimum effort is usually required.
It is for this reason a single product (Damp Seal) and easy to apply solution is proposed for plastered walls facing issues of rising dampness.
Step 1: Removal of paint / surface finish from the plastered surface
All the damaged paint coatings and surface treatment should be removed to expose the base grey plaster. It is recommended to scrape out the paint / finish using appropriate mechanical or manual means. It is also recommended to remove the surface treatment 1 feet above the affected area to ensure proper performance of the subsequent layer of Damp Seal in this case
Step 2: Application of Damp seal
Damp Seal is an epoxy-based dampness protective material. It is a three-part material which comprises of Part A (Base), Part B (Hardener) and Part C (Diluent). Mix part A with Part B to form a thick paste suitable for brush coating and apply a minimum of 2 coats of Damp Seal over the surface. If the paste becomes very viscous and not fit for brush applications (specially in cold weather) it is recommended to add Part C (Diluent) in the mix to get the brush applied consistency. Addition of Part C is optional and only required to adjust the viscosity of the mixing material (Please refer to the product datasheet for further information). Once the coating of Damp Seal has been cured, a plastic like film is formed over the plastered surface.
Step 3: Repaint / Finishing of the surface
Over the cured surface of Damp Seal, a variety of paints and other surface finishes can be applied.
Note: Damp Seal is a film forming treatment and does not integrally treat the capillary structure of the affected area. There may be chances of dampness re-appearing above the treated surface of the Damp Seal, therefore it is recommended to apply Damp Seal at least one foot above the affected area.
