Sealer Preparation

The Number One Reason For Premature Sealer Failure Is Inadequate Preparation !!! 

Most hard surface building materials are porous and can easily absorb foreign liquids. To avoid such issues a sealer can be applied. Before applying any sealer it is absolutely essential that the surface be prepared thoroughly by removing all dirt, mildew, grease etc. Please find steps below in order to accomplish such a task:

Option 1 (manual)

Instructions:

1.  Sweep surface removing loose dirt, dust and debris.

2.  Saturate surface with garden hose.

3.  Add half a cup of dish washing liquid and half a litre of domestic bleach to a bucket of water. Test with bleach dilution rates dependent on your situation.

4.  Saturate the head of a stiff bristled broom and start scrubbing the surface.

5.  Once scrubbing is complete, rinse the surface thoroughly removing all dish washing liquid and bleach.

6.  If using a water based sealer simply wait approx 20 – 40 mins before applying the sealer. If using a solvent sealer allow the surface to dry for approx 24 hours.

Option 2 (mechanical)

Instructions:

1.  Use a blower on surface removing loose dirt, dust and debris.

2.  Saturate surface with garden hose.

3.  Add half a cup of dish washing liquid and one litre of domestic bleach to a bucket of water. Test with bleach dilution rates dependent on your situation.

4.  Using a pressure cleaner, insert the chemical injector hose or venturi hose into bucket.

5.  Using pressure cleaner on low rpm apply solution liberally across surface. Do not allow to dry.

6.  Optionally saturate the head of a stiff bristled broom and start scrubbing the surface.

7.  Pressure clean surface.

8.  Once pressure clean is complete, rinse the surface thoroughly removing all dish washing liquid and bleach.

9.  If using a water based sealer simply wait approx 20 – 40 mins before applying the sealer. If using a solvent sealer allow the surface to dry for approx 24 hours.
