Techniseal WL5 Wet Look Paver Sealer and Joint Stabilizer

Why Contractors Ask for WL5 by Name

Resealing an existing patio is a different problem from sealing a new one. The old film has to be Techniseal WL1-2, WL4 or WL5 (or stripped first), and the joints have usually lost material over the years.

• Techniseal calls it the perfect recoating product for previously sealed areas. That is a specific endorsement, and it is why WL5 belongs on the truck of anyone doing maintenance and restoration work rather than only new builds.
• It stabilizes the joints while it seals. On a patio being resealed, the joints are usually the part that has degraded most, so treating both in one pass is exactly what the job needs.
• It works with polymeric sand and traditional jointing aggregates alike, which matters on older installs where you may not know what was originally used.
• Durable rich glossy finish. A full wet look rather than a satin or semi-gloss.
• Approved on porous natural stone (not granite, marble or dense stone) as well as concrete pavers, slabs, interlocking pavers, and wet cast pavers.
• Published coverage of 150 sq ft per gallon and 750 sq ft per 5 gallon makes estimating straightforward.

WL5 Specifications

Techniseal notes coverage varies with joint width and surface porosity. On a recoat, the old surface is often thirstier than a new one, so budget above the published figure on weathered work.

Where WL5 Works

WL5 is the maintenance and restoration sealer in this line.

• Resealing paver patios and driveways previously sealed with Techniseal WL1-2, WL4 or WL5
• Restoration work on faded and weathered installations
• Surfaces with degraded sand or aggregate joints
• Porous natural stone patios and walkways
• Wet cast paver installations
• Concrete slab surfaces
• New installs where a full gloss wet look is specified

How to Use WL5

Follow the official Techniseal instructions and safety data sheet, linked below. This is the shape of the job:

1. Clean the surface thoroughly and let it dry completely.
2. On a recoat, confirm the existing sealer is Techniseal WL1-2, WL4 or WL5; strip any other or unknown sealer first.
3. Top up any joints that have lost material.
4. Apply evenly per the technical data sheet, keeping a wet edge and avoiding pooling.
5. Observe ventilation and safety requirements throughout.
6. Respect recoat and cure times, and keep traffic off through the full cure.

On a recoat, knowing what is already on the surface matters more than anything else. An incompatible sealer over an old film can lift, cloud, or stay tacky, which is why Techniseal requires stripping any unknown coating first.
