Our exclusive DiaoSeal Standard Seal Service guarantees to STOP leaking showers and shower leaks at the source.

Step 1. The Appraisal

A fully trained and authorised DiaOseal waterproofing technician will assess the shower or area in question, and explain the DiaOseal waterproofing process to the owner, resident or representative.
(NB: if any tiles are drummy, cracked or require replacement, then this is a separate procedure and an additional cost).

Step 2. Plumbing

A FREE shower water pressure test will be carried out to determine if there any plumbing faults within the shower breeching piece. If the shower leakage is caused by a plumbing issue, our technician will make arrangements to seal the shower once a qualified plumber has rectified the plumbing problem.

A full tap service will be carried out if required on standard spindle assemblies. This includes: ‘O’ rings, fibre washers, jumper valves and reseat.
(NB: This step is not possible if a gravity-feed hot water system is installed or where ceramic disc ware or mixers have been fitted).

Next, the tile penetration will be sealed to prevent any water behind the tap flanges entering into the wall cavity or down behind the tiles.

Step 3. Shower Preparation

Any previous attempts to seal the shower will be removed. The floor waste (drain) will be inspected and cleaned, and if required, sealed. Any additional silicone to the inside of the shower screen will be removed and then cleaned for a high performance neutral cure silicone sealant designed to resist the growth of mould and mildew in high humidity.

Step 4. Grouting

The technician will assess the existing floor grout for deterioration, cracks and efflorescence. The grout will then either be topped up (if required) prior to sealing, or our DiaoSeal sealer applied directly to existing floor grout.

Any cracked tiles will be repaired using our product or the tile replaced as costed on appraisal.

The DiaOseal Standard seal normally involves regrouting the shower walls with a smooth, flexible, mould-resistant grout. (NB: if not cement grout, epoxy grout or an apparent risk of damaging the existing wall tile exists), however if the existing wall grouting is in excellent condition, this is omitted. If the walls are not regrouted, the technician will apply our DiaoSeal sealer as described in step 7.)

Step 5. DiaoSeal product Preparation

Our technician will prepare all wall tile and floor tile junctions along with any vertical internal junctions – using specially engineered diamond burs. This process ensures a clean product bond to the tile, instead of the product adhering to the glaze of the tile (as our competitors’ does).

Step 6. DiaoSeal Application

DiaoSeal will be applied to the prepared main movement areas. The application is in form of a 5mm coving. The product will be colour- matched to the shower to give a neat appearance. DiaoSeal has been specifically designed for wet area sealing and has the strength to withstand normal building movement. It will not crack, deteriorate or let water penetrate through the junctions. It does not dissolve and is not weakened by strong chemical cleaning agents.

Step 7. DiaoSeal Sealer

A clear sealer applied to the entire tiled surface area of the shower. This sealer deeply penetrates the grout, narrowing the pores, to help strengthen and seal it. Any micro fractures in the glazing of the tile will be sealed. This prevents any unnecessary tile removal.
