We know from experience that when it rains in Malta and Gozo, it really rains!!
When the water starts seeping its way in through inadequately waterproofed ceilings and walls, it is time to address the problem.
This is R.A & Sons guide on Waterproofing your property. Besides RALASTIC, we have four new products to be used effectively in waterproofing your home or building.
Planning & Preparation
It is essential to assess the substrate for humidity. This must be addressed first before commencing any work. If you are unsure of the humidity level then please ask for assistance from R.A & Sons.
The area must be cleaned properly. It is to be free from dust and any other loose particles. Any superficial imperfections such as holes or cracks must be filled with any suitable putty or touch up mortar and then smoothed.
Make sure any previously painted surfaces are in good condition and in case of need, remove the decaying, non-adhering and high thickness parts, by sandblasting or brushing them out, as well as any mould or algae present.
It is advisable especially on outside walls to use RAPRIMER. This allows a surface to harden, increasing the resistance in the absorption of the masonry, so that when RALASTIC is applied it can form an effective waterproof layer.
Leave RAPRIMER a minimum of 12 hours and up to 24 hours to dry dependent on weather factors.
After RAPRIMER is dry, apply two coats of RALASTIC. These layers must be evenly applied to allow proper compactness and coverage preventing water seepage between the membrane and backing. Seal all the corners and bends between the walls and floor.
RALASTIC can be applied by means of a hard bristle brush or a wool paint roller.
Let 24 hours rest between the 2 layers.
It is highly recommended to not use less than 1 Kilo per Sq Metre.
