Caring for your Plaster System

1.

The Sto plaster system must be regularly checked and washed at least annually.

Use water or mild chemical clean, and pay particular attention to non-rain washed areas. Most localised grime can be removed with a warm water /detergent solution, brushed on and rinsed off with fresh water. 

To clean, use a high-pressure hose. Only professional cleaners should use water blaster equipment.

Care must be taken to avoid damaging the surface, joinery seals, building components and adjacent surfaces.

2.

Living in coastal areas as we do, homes and buildings should be hosed down after storms to remove salt residue, which can erode surfaces.

3.

It is important to monitor the condition of the plaster system in relationship to the following; building sealants, joinery, material transitions, stress points, narrow widths, parapets & balustrade tops, dissimilar material junctions, handrails, roofs, gutters, decks for any deterioration or defects so as repairs / remedial action can be initiated immediately.

4.

Ground levels must be maintained in accordance with the Building Code (ground floor level 100mm to paved and 150mm to ground). Grass, moss and weeds must be cut or removed regularly. Interior floor levels must always be above ground level unless specifically designed with appropriate waterproofing.

5.

Vegetation should be trimmed back from wall surfaces to prevent physical damage and encourage light and air circulation to discourage mould growth on the surface. Areas beneath decks should be kept clear and cleaned at least annually.

6.

Tanking, foundations, paths and decks adjacent to the plaster system should be checked to ensure they are not damaged and all drainage points & clearances are clear. Paths & paving should be laid with against a slip layer to prevent settlement / contact damaging the plaster.

7.

All penetrations through the plaster system must be examined to establish that they are weather tight and any fixtures checked that they are secure. Any new penetrations and fixings must be in accordance with the Sto details.

8.

Physical damage must be addressed immediately to avoid any further damage, and must be repaired using the appropriate Sto Plaster System. Any areas of Cladding identified as faulty must be temporally sealed until a Sto Contractor can initiate remedial work.

9.

When recoating is required (in the eighth to tenth year) to maintain long-term film integrity this must be carried out using the appropriate Sto Coating System.

10.

Where a colour change is required, Sto / Quality Finishes should be consulted for a specific recommendation.
