• Ensure surface is dry and in sound condition – free from dust, rust, grease, oil, algae, fungus or any loose or flaking particles.
• Do not apply if rain is expected.
• Ensure each coat is dry before commencing next coat (if not dry this could lead to bubbling and wrinkling)
• Do not overspread or apply too thin.
• Regular maintenance coats will add and enhance the already existing film thickness.
1. Small cracks up to 1mm must be sealed with SealTite Crack Sealant.
2. Cracks larger than 1mm must be opened up to a width of 5mm and depth of 10mm. Fill with plaster-mixture mixed with SealTite C-Max. (See instructions)
3. If concrete or cement surface is powdery, loose or in poor condition, then first apply one coat of SealTite PremBond at a rate of 8m²/ℓ. Allow to dry for 2 hours.
4. Ensure surface is completely bonded and in sound condition before proceeding.
5. Ensure surface is even (if not, apply screed or thin layer of SealTite 550 using a squeegee or roller to even out surface).
6. Lay down SealTite Duramesh Membrane (1m wide roll) over whole surface to be waterproofed. Overlap membrane edges by 100mm. Cut membrane with scissors to required length.
7. Apply SealTite MaxPly straight onto SealTite Duramesh Membrane by using a block brush or roller. Apply at a rate of 2m²/ℓ.
SealTite MaxPly will penetrate through SealTite Duramesh Membrane and bond it to the surface. Ensure no bubbles or wrinkles in SealTite Duramesh Membrane during application.
8. Do not finish in corners. Do above application up sides and over the top of vertical parapet walls (where applicable). Cut and use separate SealTite Duramesh Membrane strips for top of parapet walls and vertical areas on parapet walls. Overlap membrane edges by 100mm.
9.Then apply SealTite MagMar as the topcoat.
