202 Vertical Surface Repair Mortar
Manufacturer: Rawlins Paints
202 Vertical Surface Repair Mortar is a fast setting epoxy repair mortar for vertical and overhead repairs providing a strong and durable, weatherproof repair for concrete, brickwork, stonework and steel substrates. Ideal for repairs to spalled or damaged concrete structures and cosmetic refurbishment of old stone and brickwork.
202 Vertical Surface Repair Mortar is a solvent free Epoxy resin system, together with specially graded lightweight fillers. The mixed mortar has excellent application characteristics, allowing overhead and vertical repairs to be easily accomplished.
202 Vertical Surface Repair Mortar is supplied as a three pack material, pre-weighed to allow easy onsite mixing and use. Surfaces must be primed with 405 Tack Primer prior to the application of 202 Vertical Surface Repair Mortar to ensure good adhesion and durability.

|Pot Life:||50 minutes @ 20°C|
|Compressive Strength:||45 MPa|
|Tensile Strength:||8 MPa|
Excellent resistance to 25% hydrochloric acid, 20% sulphuric acid, 10% citric acid, 40% sodium hydroxide, diesel and petrol. Very good resistance to 10% lactic acid, 20% phosphoric acid, Good resistance to many common industrial chemicals.
The substrate shall be sound, clean and free from laitance, dust, oil, grease and other contaminants.
Smooth substrates should be roughened by mechanical means to form a ‘key’ in order to optimise adhesion. Scabbling, grit blasting, high pressure water jetting or needle gunning are satisfactory forms of preparation.
Any corroded re-enforcing steel shall be abraded or grit blasted to remove all scale, rust, etc.
If application of the 202 Vertical Surface Repair Mortar is to be delayed then a coat of 404 Epoxy Metal Primer should be applied as an anti-corrosive holding primer for prepared steelwork.
Please consult our Technical Department for specific advice.
Mix and apply a coat of 405 Tack Primer in accordance with the product data sheet instructions.
Pour the contents of the CURING AGENT container into the BASE container and mix thoroughly by spatula or low speed drill/stirrer. The mixed resins shall be poured into a forced action mixing vessel, (Creteangle bucket or similar), and the FILLER added steadily whilst the mixer is in motion. Mix for 2-3 minutes until a uniform material is achieved.
- By Volume = 2.1 Base : 1 Curing Agent
- By Weight = 100 Base : 42 Curing Agent
Whilst the 405 Tack Primer remains in a ‘tacky’ condition, i.e. within 90 minutes of application, apply the 202 Vertical Surface Repair Mortar by wood float, ensuring good compaction, and then close and finish with a steel float. Where a roughened profile is required, finish with a plastic float.
202 Vertical Surface Repair Mortar may also be placed by gloved hand for comparatively inaccessible applications. Chequer board application is recommended for larger areas of rendering.
Application thickness of up to 50mm per layer may be achieved. If additional layers are required, scratch finish the first layer and then re-prime the following day prior to subsequent applications.
Clean equipment with 109 Tool Cleaner prior to curing of the mortar.
202 Vertical Surface Repair Mortar will have cured sufficiently after 24 hours @ 20°C to be put back into most kinds of service.
7 days cure @ 20°C will be required to ensure optimum mechanical properties and full chemical resistance.
- Do not apply to wet or uncured concrete surfaces.
- Do not apply at temperatures of 3°C or less.
It is your responsibility to read the Product Data Sheets (available below) before you place an order and prior to application of the product. The content of this website is our best recommendation and is not advice. Coverage rates quoted are approximate, you agree that coverage depends on the condition of the substrate, surface absorption, texture and application method. We ALWAYS recommend a trial area is coated to ensure the product meets your requirements before use.

Question: Does this need to be built up in layers?
202 Vertical Surface Repair Mortar can be applied to a thickness of up to 50mm per layer. If additional layers are required, scratch finish the first layer and then re-prime the following day with 405 Tack Primer prior to subsequent applications.
