 Roof tile sealers

sealersSmartseal Roof sealer is a pre-mixed, colourless blend of high-grade acrylic resin polymers and aromatic solvents. It is available in 25 litre and 5 litre drums to trade or diy customers

The sealant is formulated to impregnate concrete roof tiles to give long term protection and durability. Smartseal roof sealer penetrates deep into the tile and can be coloured to give a complete transformation of the existing roof. Two coats of roof sealer are applied to give maximum resistance to the weather and restrict future moss growth.

Smartseal roof sealers are designed to give durable coloured coatings that are waterproof, flexible and resistant to UV deterioration. Their resistance to the weather ensures that re-introduced deep colouring is maintained. The roof sealers not only transform the roof's aesthetic appeal, but also improves the durability and resistance to mould and algae re-growth.

[img326-S-R]STEP 1: Roof Cleaning

The roof should be thoroughly cleaned by high pressure washing this will remove moss, algae, lichen, dirt and pollutants. Remember to take care during the roof cleaning process not to block existing gutters and downpipes.

STEP 2: Fungicidal Wash

A treatment of Smartseal fungicidal wash is recommended to eliminate the underlying active infestation of moss & lichen spores. This will help prevent future re-growth and minimise further maintenance.

STEP 3: Roof repairs

At this point it makes sense to repair any damaged areas on the roof. Defective mortar between crests, ridge and hip tiles can be hacked out and re-pointed using a fibre re-enforced polymer mortar. Also any loose ridges and crests can be re-bedded and damaged roof tiles replaced.

STEP 4: Roof Sealer Application
Ensure roof tiles are clean and dry prior to application of roof sealer. Apply Smartseal roof sealer with a sprayer unit, brush or roller. The first application must be applied to the surface and allowed to dry past tacky prior to applying the second coat. Avoid application in strong, direct sunlight and do not apply if rain is likely within 4 hours of application.
