Description
PCP EleRoof Universal 
PCP EleRoof Universal MMA Primer is a flexible, fast-curing liquid primer designed for use as part of the EleRoof PUMA waterproofing system. It prepares suitable substrates and provides adhesion for the subsequent waterproofing layers, helping create a reliable bond throughout the system.
Formulated for roofing and waterproofing applications, EleRoof Universal MMA Primer is suitable for a range of substrates, including damp and dry concrete, wood and metal. Its rapid-curing MMA formulation makes it suitable for projects where installation speed and reduced weather-related delays are important.
Key Benefits
- Universal MMA primer for the EleRoof PUMA waterproofing system.
- Flexible formulation.
- Very fast curing.
- Liquid formulation for straightforward application.
- Suitable for low-temperature applications, subject to manufacturer guidance.
- Designed to adhere to suitable damp and dry concrete substrates.
- Suitable for appropriate wood and metal substrates.
- Prepares surfaces for subsequent EleRoof waterproofing layers.
- Typical system application rate of approximately 0.4kg/m².
- Forms part of the complete EleRoof PUMA system tested to B-Roof T4.
- Suitable for new concrete aged 28 days or more.
- Supplied in a 20kg container.
Suitable Applications
PCP EleRoof Universal MMA Primer is designed for use within compatible EleRoof waterproofing systems on suitable substrates, including:
- Concrete roof decks.
- Concrete floor slabs.
- New concrete aged 28 days or more.
- Suitable damp concrete surfaces.
- Dry concrete surfaces.
- Wooden roof decks.
- Plywood roof substrates.
- Metal roof substrates.
- Balconies and terraces.
- Roof refurbishment projects.
Important: Bitumen and asphalt substrates may be treated differently within the EleRoof PUMA system. PCP's system information states that the PUMA membrane can be applied directly to suitable asphalt without primer. Confirm the correct system build-up for the substrate before application.
EleRoof PUMA Waterproofing System
EleRoof Universal MMA Primer forms the preparation and bonding layer of the EleRoof PUMA roofing system. It is used on suitable substrates before application of the reinforced waterproofing membrane and protective topcoat.
A typical EleRoof PUMA system build-up comprises:
- PCP EleRoof Universal MMA Primer: Prepares suitable substrates and provides adhesion. Typical application rate approximately 0.4kg/m².
- PCP EleRoof PUMA Membrane: Provides the flexible waterproofing layer, incorporating reinforcement fleece throughout the system.
- PCP EleRoof MMA Top Coat: Provides the protective finishing layer.
For maintenance walkways where foot traffic is expected, the manufacturer's system sheet describes a quartz-blinded topcoat followed by an additional topcoat to encapsulate the aggregate.
The complete EleRoof PUMA system has achieved a B-Roof T4 test pass. This classification relates to the tested system build-up and should not be interpreted as a standalone fire classification for the primer.
Application Guidance
Substrate Preparation
Substrates must be suitably prepared, sound and free from loose material, dust, oil, grease and other contaminants that could affect adhesion. Follow PCP's preparation requirements for the specific substrate.
Mixing and Catalyst
MMA products require the correct catalyst dosage to initiate curing. The catalyst quantity and mixing procedure must be taken from the manufacturer's current product instructions, taking account of the ambient temperature and application conditions.
Application
Apply the primer evenly to the prepared substrate using the appropriate application equipment and the manufacturer's specified application rate. PCP's EleRoof PUMA system sheet gives a typical primer application rate of approximately 0.4kg/m².
Allow the primer to cure as directed before applying the subsequent EleRoof waterproofing layers. Actual consumption and curing times will depend on substrate condition, temperature and site conditions.
Do not assume that all substrates require the same primer treatment. In particular, confirm the manufacturer's instructions for bitumen and asphalt surfaces before proceeding.

Frequently Asked Questions
1. What is PCP EleRoof Universal MMA Primer used for?
It is used as the primer layer within the EleRoof PUMA waterproofing system. It prepares suitable substrates and provides adhesion for the subsequent waterproofing membrane.
2. Can EleRoof Universal MMA Primer be applied to damp concrete?
Yes. The product information identifies adhesion to suitable damp concrete as one of its benefits. The substrate must still meet the manufacturer's preparation requirements.
3. What substrates can the primer be used on?
It is intended for suitable concrete, wood and metal substrates within the EleRoof system. Always check the manufacturer's guidance for the particular substrate.
4. Can it be used on new concrete?
Yes. The product information specifies new concrete aged 28 days or more.
5. How much primer is required per square metre?
The EleRoof PUMA system sheet gives a typical primer application rate of approximately 0.4kg/m². Actual consumption will depend on the substrate and site conditions.
6. Does the primer cure quickly?
Yes. It is described as a very fast-curing MMA primer. Actual curing times depend on temperature, catalyst dosage and site conditions.
7. Is the primer itself B-Roof T4 rated?
No standalone B-Roof T4 classification should be attributed to the primer. The complete EleRoof PUMA waterproofing system has achieved a B-Roof T4 test pass when installed in the tested system configuration.
8. Does bitumen roofing require this primer?
Not necessarily. PCP's EleRoof PUMA system information states that the membrane can be applied directly to suitable asphalt without primer. Check the current system guidance before application.
