Raincheck Limestone Sealer 5 Litre – Breathable, Colourless Water Seal for Limestone

Raincheck LS is a colourless water-repellent for limestone based on UV resistant silane-siloxane resins. The composition of Raincheck LS allows the water-repellent material to bond to the carbonates in limestone. Raincheck LS can be used on old and new buildings to protect against penetrating damp. The product is suitable for the treatment of absorbent limestone rather than very dense types. Benifits of using Raincheck LS: Rapid curing Can be used on old and new buildings to protect against penetrating damp and to keep limestone clean. Will not block the pores so water vapour is able to escape. Easy to apply by brush or by spray Penetrates 2 – 10 mm. Application One litre of Raincheck LS will cover 2-4m². Best applied when it has not rained for 24 hours. Application with brush or lambswool roller This method is recommended if the areas to be treated are small or if the wall has a large number of windows. Special care should be taken to ensure that sufficient Raincheck LS is applied (1 litre product per 2.5m² to 3.5m² per coat), since the success of the treatment depends on this. At least two coats should be applied wet on wet. Application by coarse spray This method is recommended when treating large areas. Application should start at the highest point working from side to side allowing ‘run down’ of the fluid for 15 – 30 cm. It is advisable to flood coat twice (Raincheck LS being applied wet on wet). On poorly absorbent surfaces one coat of Raincheck LS will usually suffice.
