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 comes 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.
