Tarmac Multipurpose Mortar is formulated to deliver reliable performance for a variety of masonry applications. Its factory-produced nature means consistent quality in every bag, which is crucial for achieving strong, durable bonds and attractive finishes.
Preparation: Ensure your mixing container is clean and free from contaminants. Measure the desired amount of dry mortar.
Water Addition: Gradually add clean water to the dry mix while stirring. Info needed: [Specific mixing ratio or recommended water volume per 5kg bag for optimal consistency]. Aim for a workable, plastic consistency – not too stiff, not too runny. A good test is if it holds its shape on a trowel without slumping.
Mixing: Mix thoroughly for 3-5 minutes, either manually with a shovel or using a mechanical mixer, until a consistent, lump-free paste is achieved. Allow it to stand for a few minutes (slake) then remix briefly.
Surface Preparation: Ensure all surfaces to be mortared are clean, free of loose material, dust, and excessive moisture. Dampen highly absorbent substrates to prevent them from drawing too much water from the mortar too quickly.
Application: Apply the mortar using a trowel for bricklaying, pointing, or patching. Work in manageable sections, as the mortar will begin to set.
Batch Size: Mix only as much mortar as you can use within the working time (typically 60-90 minutes, depending on temperature and humidity) to prevent hardening.
Temperature: Avoid applying mortar in extreme hot or cold temperatures. Ideal application temperatures are generally between 5°C and 30°C.
Curing: Proper curing is critical for strength development. Keep freshly laid mortar damp for at least 3-7 days, especially in warm or windy conditions. This can be done by misting with water or covering with plastic sheeting.
Cleaning: Clean tools immediately after use with water before the mortar hardens.
To begin using your Tarmac Multipurpose Mortar, gather the following:
Mixing Equipment: A clean bucket or mortar tub, and a shovel or mechanical mixer.
Measuring Tools: For accurate water addition.
Application Tools: Trowel, hawk board, pointing tools, brushes.
Safety Gear: Essential for protection during handling and mixing.
Eye Protection: Safety glasses or goggles to prevent dust and splashes.
Gloves: Durable work gloves to protect skin from alkaline mortar.
Dust Mask: P2 or P3 respirator to prevent inhalation of fine dust particles.
This multipurpose mortar is generally compatible with common masonry materials, including:
Clay bricks
Concrete blocks and bricks
Natural stone
Rendered surfaces for patching
Always perform a small patch test on an inconspicuous area if you are unsure about compatibility with specific or unusual substrates.
Unmixed Mortar: Store the unopened 5kg bag in a cool, dry, and frost-free environment. Ensure the bag remains sealed to prevent moisture ingress, which can cause premature hardening. Keep off the ground on pallets if possible.
Mixed Mortar: Once mixed with water, use the mortar within its working time. Do not attempt to re-temper (add more water to re-soften) mortar that has begun to set.
Cured Mortar: Protect freshly applied mortar from rapid drying, frost, and heavy rain for at least the first 24-48 hours. Proper curing ensures maximum strength and durability.
