ARDEX R3E Solvent Free Epoxy Primer and Bonding Agent is a two component, solvent free, epoxy resin for use on sound concrete, cementitious surfaces, calcium sulphate-based screeds and smoothing compounds.

Ardex R3E is known as a moisture tolerant epoxy primer which means that it can perform effectively on surfaces with less-than-ideal or uneven conditions. Including wet and dry weather conditions or from water spillages. Blind Ardex R3E with Ardex Fine Aggregate prior to the installation of polyurethane screeds and self-smoothing epoxy floor coatings.

When surfaces are porous we recommend using more than one coat of Ardex R3E to get the desired effect.

Please note that your order may need to be split into separate packages if over 30KG.

All of the above is based on UK Mainland deliveries, further charges may be incurred if the delivery address is outside of this.

We are also currently unable to deliver outside of the UK on our regular carrier so if you require delivery outside the UK please call or email the details to the office as we reserve the right to refuse service or refund orders based on this.

Guarantee next day delivery.

Some of our products have a note that states – if ordered before 1pm and being delivered to UK mainland on a next day basis.

Please note that given the current circumstances alot of carrier companies are struggling to keep up with demand and although we do book these deliveries as next day services, the carriers cannot always fulfil these and an extra day may be required.

A high percentage of our advertised goods are stock items but be aware that if you are taking very large quantities of stock that we may not be able to fill your order fully on first delivery. Please call the office to check to not be disappointed.

We are also an active trade counter and part of a larger network of companies so stock can be taken at any time but we will always aim to deliver your goods as soon as possible.

Also if ordered along side goods that we cannot guarantee next day delivery on, these will be delivered based on the schedule of the other item.

Signature required on delivery.

The carrier we currently use requires a signature for all deliveries as a proof of delivery. If you cannot guarantee someone will be home to receive this please leave delivery instructions for a safe place or neighbour to leave your goods with. Due to covid and new contactless deliveries, our carriers will not require a signature but will take down the recipients name as POD.

If no one is available to take the delivery, the courier will leave details at the address to rearrange delivery or may leave with a neighbour. Note we may need to make an additional handling charge for the return and re-delivery if a package is unable to be delivered multiple times due to no one being home to receive this. Due to covid our carriers are restricting the number of re-delivery attempts.

After three attempted deliveries our carrier will return the goods to ourselves and in this worst case situation, we may cancel the order and refund your money, excluding any additional charge for the return and re-deliveries.

Materials delivered from our own stock.

Normally 1 – 2 days (this can sometimes be longer if we are waiting for manufacturers’ stock to arrive into ours).

If the order is placed before 1:00pm and all of the items are in stock, then we will endeavour to dispatch your order same day for delivery the following day.

This still applies for deliveries out of our local area but please note that we use independent carriers so be aware that there may be external factors which we cannot control (e.g Far out postcodes or local traffic situations)

Materials delivered direct from the manufacturer.

There may be some occasions when it is more efficient or cost effective to have the materials shipped direct from our suppliers to the customer.

We will place the order immediately upon receipt of your order but this can sometimes take a few working days depending on the manufacturers production schedule or carrier used.

We will always endeavour to get the goods to the customer at the earliest possible date but if these are urgently required, please speak to us to check.

Ardex R3E is a two component Epoxy Resin Primer and Bonding Agent. Ardex R3E forms a primer/bonding layer on most dry substrates, especially smooth or dense surfaces in internal and external situations. It can be used to prime Ardex K301 or for Ardex Screed size.

It is suitable for use on sound concrete and cementitious surfaces that are damp, calcium sulphate based screeds and smoothing compounds.

Ardex R3E should be applied using a brush or a short to medium-sized pile roller. This will ensure coverage is achieved sufficiently.

*For advice on specific uses, please contact our helpful team.

Yes, once the product is mixed appropriately following the manufacturer's instructions, it can be applied using an appropriate brush or pile roller. One or more coats may be required to ensure that a uniform coating is achieved and to compensate for differences in surface porosity.

Ardex R3E Solvent Free Epoxy Primer can be used over dense surfaces and keyed to lay ARDEX Smoothing Compounds above 6mm.

The working time for this product is 20 minutes at 20°C. For walkability, you should leave 6-8 hours at the same temperature. The overcoat time is 8 hours, but it can be a maximum of 24 hours. You should ensure the material is cured before attempting to install cement or sand screed.

It has a storage life of not less than 12 months if stored in the correct conditions and in the original unopened containers.

Store in dry conditions in the original containers, ensuring they remain unopened until use.

No, this product should only be used on damp cementitious floors, and is not suitable for use on existing tile or flooring. Applying this on top of an existing tile or flooring surface may not provide a suitable bonding surface, leading to poor adhesion. However, it can be used as a primer or bonding agent when applying an Ardex Screed.

*For advice on specific uses, please contact our helpful team.

Before application can begin, you must ensure that the concrete or screed substrate is hard, sound and free of dust. Ensure any other barrier materials such as paint, lime coatings, plaster, curing agents, laitance, or adhesive residues are cleaned and removed beforehand to ensure no inhibition of adhesion to the substrate. To effectively remove polish, wax, grease, oil and similar contaminating substances, use Ardex DGR Degreaser. It is important that you brush and vacuum any dust and fines using the appropriate surface preparation equipment to ensure the surface is prepared to a suitable depth with a sound hard surface ready for treatment.
