Adhesives for Construction in Namibia

A north-facing joint in Windhoek cycles through more thermal movement in a week than a European joint sees in a season — undersized joints and cheap sealants simply tear. Size joints for movement, use a proper silicone (our trade grades in black, grey, white), tool onto clean primed surfaces, and the joint lasts years instead of a summer.

Respect the substrate temperature: No More Nails on a sun-heated wall skins in moments, so work shaded elevations in the morning, apply to the cooler face, and get positioning right the first time. For exterior fixing in permanent sun, step up to epoxy anchoring — mounting adhesives have limits our climate finds quickly.

The 20-litre acrylic floor adhesive over a screed that is genuinely dry — and “genuinely” is the Namibian catch, because fast-dried surfaces hide wet cores that later blow the bond. Moisture-test, prime porous screeds, trowel at the specified rate, and roll the floor. Nine lifting-vinyl callbacks in ten trace to screed moisture, not adhesive.

For many repair and mounting cases, yes: Pattex Power Epoxy (Liquid Steel) bonds, fills and repairs metal-to-masonry connections, re-sets pulled anchors, and mounts fixtures where rebar or services forbid drilling. It is not a substitute for engineered structural anchors where those are specified — but for the daily site problems between those extremes, it is the toolbox answer.
