Drybase Universal Mortar

When restoring & waterproofing damaged concrete, masonry and stonework, mortar resilience is paramount. For subsurface structures such as basements, swimming pools and lift pits, the outside stresses put on mortar are even higher.

Repair mortars are used in some of the harshest environments and weakest points of a structure. You need a repairing and waterproofing mortar that can handle such a demanding situation.

Safeguard Europe has carefully developed Drybase® Universal Mortar - a pre-blended cementitious waterproofing & repair mortar to maintain and renew the integrity of indoor and outdoor structures.

Waterproof and repair existing structures

Mortar Joint

Drybase® Universal Mortar's cement and graded quartz sand based composition gives it strong resistance to abrasion & frost and makes it waterproof.

It is perfect to protect critical points such as floor-to-wall junction fillet seals, to repair damaged concrete or even shutter tie holes. Reprofiling can be achieved through a layered application until the surface is smooth.

Frost and abrasion resistant

Drybase® Universal Mortar's resilience makes it more than suitable for general repairs, levelling and re-profiling.

It is resistant against frost and de-icing salt, making it great for use in colder external environments such as concrete step repairs.

Damp-proof in a single breathable coat

breathable protection

Drybase® Universal Mortar can be used as a single-coat tanking slurry and damp-proofing barrier. Keep wind-driven rain and outside water sources from causing penetrating damp with Drybase® Universal Mortar.

Vapour permeability is important to allow for healthy vapour passage, especially in damp and humid areas. Drybase® Universal Mortar is vapour permeable as well as fully waterproof. Maintain comfortable humidity levels in demanding environments like basements and tunnels.

Implement small fixes, fast

Swimming pool

Eliminate leakage and water ingress in lift pits and swimming pools. Application can be made in 6-12mm layers on horizontal, vertical and overhead surfaces. Choose your layer thickness depending on the scale of the project. Complete small projects like drinking fountains, lift pits and ponds quickly and efficiently with thinner layers of mortar. Carry out smaller repairs and fixes as needed.

Drybase Universal Mortar is non-slump and high-build, ensuring ease of application and stability as it cures.

Pave the way for Drybase® Tanking Slurry

Drybase Tanking Range

Drybase Universal Mortar can be used to create a suitable application surface for Drybase Tanking Slurry or Drybase Flex Membrane as the first part of the Drybase Tanking Treatment. Also compatible with Dryzone Renovation Plasters.

Drybase Universal Mortar comes ready-mixed and pre-bagged for ease of use and to minimise waste. It can be used to repair concrete, masonry and natural stonework and is applied with a trowel or render spray equipment. It can be used on horizontal, vertical and overhead surfaces.

Application

Drybase Universal Mortar is applied with trowel or suitable spray equipment. Apply a minimum of 6 mm (approx. 12 kg/m2) and a maximum of 12 mm (approx. 24 kg/m2) in one working cycle. For small areas such as coves, fillets, local repairs and shutter tie holes Drybase Universal Mortar may be applied in layer thicknesses exceeding the above value.

Pour Drybase Universal Mortar over horizontal surface, then compact and strike off. After initial hardening it can be trowelled or given a ‘brushed’ finish to provide a non-skid quality.

Apply Drybase Universal Mortar to vertical surfaces like normal render. If several coats are required it is recommended to apply the next coat whilst the previous coat is still damp at the surface.

The waiting time before applying the following coat depends on local climatic conditions such as humidity, temperature, etc. The previous coat must be textured by suitable means (such as a soft brush) whilst still plastic to form a key.

To maintain workability of the material do not add water, simply re-stir the mixture.

Do not apply at temperatures below 5 °C, or to a frozen substrate.

Trowel Application

Apply a scratch coat first for maximum adhesion to the substrate. Ensure that all cavities in the substrate are filled in order to exclude any trapped air.

Spray Application

Drybase Universal Mortar can be applied with a suitable mortar spraying device. For maximum spray pattern it should be possible to adjust volume of product as well as air pressure and volume.

The nozzle diameter is approx. 10 mm. The first layer of Drybase is applied in a circular motion with the spray nozzle held at a 90° angle to the substrate. The material is then flattened and trowelled or keyed for a further layer.

Curing

Keep damp for at least 5 days and provide suitable protection against extreme weather conditions (e.g. sun, wind, frost) while setting. The freshly treated surfaces should be protected from rain for a minimum period of 24 hours.

Plastering/Coating

Surfaces treated with Drybase products which are to be coated or painted should be left to cure for 4 weeks. When a plaster or render finish is required on top of a Drybase treatment it is essential to apply a rough cast of sand and cement on the final Drybase coat while it is still tacky. Onhardened Drybase surfaces apply an appropriate bonding agent, such as SBR before rendering. Coatings on top of a nDrybase treatment have to be alkali resistant. Decorative coatings applied on the negative water pressure side should be water vapour permeable.
