1/ NEW CONCRETE SLAB
The Armtec new slab waterproofing system is ideal for new slabs and has been designed to handle normal movement and settling of a new concrete slabs. Screed levels needs to be checked for adequate water flow before preparations. Make sure the area to be waterproofed is clean and that all loose debris have been removed.
2/ PRIMER/BINDER - PENETRAR
Coat the entire slab area to be waterproofed with Penetrar. Penetrar binds dustiness, enhances the substrate and promotes adhesion for the waterproofing.
3/ MEMBRANE - ARMTEC MESH
The Armtec Mesh is an alkali-resistant glass fibre mesh used to reinforce waterproof protection layers, antifracture membranes and cementitious smoothing and levelling layers.
4/ ADHISION - BASE
Use BASE to embed the Armtec mesh into the surface of the concrete slab. BASE is a combination cementitious admixture emulsion and is used to achieve the required adhesion of the Armtec mesh to the concrete slab.
5/ FILLER - CAVITY FILLER
For a smoother finish, the entire surface can be coated with Cavity Filler before waterproofing is applied. Cavity Filler has extreme adhesion properties to most substrates like tiles, wood and metal, including bituminous systems like touch-on.
6-8/ WATERPROOFING - HYDROSEAL HF
Apply 3 to 4 layers of HydroSeal HF over the entire concrete roof slab. HydroSeal HF is a co-polymer, high-performance universal waterproofing membrane.
9/ FINAL COAT - HYDROSEAL
For highly trafficable areas it is advisable to do the & final coat of waterproofing with HydroSeal, which will produce a harder finish than HF.
